2. The doors lock or unlock depending upon which sensor was touched on the handle. The unlock button is locatedon the inside of the handle and the lock button is located on the outside face of the handle. The rear doorhandles are only equipped with an unlock sensor.

3. The driver front door IA feature either unlocks the driver door (if stepped unlock is enabled) or all four doors (ifstepped unlock is disabled). The IA feature always locks all four doors when the lock button is touched. Refer toStepped Unlock Programming in the Workshop Manual for programming information.

4. The passenger front door IA feature always locks or unlocks all four doors.

5. The rear doors IA feature always unlocks all four doors.


LESSON ONE LECTURE

Intelligent Access (IA) Logic and Power Flow Ignition ON and Starting

Push Button Start Summary

1. When the start/stop switch is pressed, the RFA module starts key initialization sequence by activating the 3interior passive start antennas. The antennas transmit a low frequency signal in approximately a 3 ft. radiusof each antenna.

2. If the IA key is within range, the IA key activates.

3. When the IA key activates it sends the PATS identification code to the RFR via a high frequency signal.

4. The RFR interprets the high frequency signal from the IA key and sends the information to the RFA over theLIN (Kline) network.

5. If the RFA determines that a programmed IA key is inside the vehicle, it communicates this information to theBCM and the ignition transitions out of off.

6. When the ignition transitions out of off and modules initialize, the RF , BCM and PCM exchange theiridentifications

7. If each of the modules receive the correct identification from each other, PATS disables and allows the engineto start.


LESSON ONE LECTURE

Passive Entry/Passive Start (PEPS) Enhancements

Starting with the 2013 or 2013.5 MY all PEPS vehicles will introduce a new functionality that provides helpfulwarnings to customers when exiting their vehicle.

1. Ignition ON Alert

The new Ignition On alert provides a warning to the operator when the vehicle is parked with the ignition ONand the driver door is opened. A 10 second warning chime is sounded when the vehicle is powered up but notready to drive. The same warning chime will be sounded if the driver’s door is ajar and the vehicle is ready todrive. In this case, both a door ajar and an associated Engine ON or Ready to Drive message will be displayed inthe message center along with the warning chime.

2. Passive Key Not Found Alert

When the customer exits the vehicle with their passive key and the vehicle is powered up, a new Passive KeyNot Found alert will be provided when the last door closes. The alert consists of two horn chirps indicating theyare exiting their vehicle in a powered up condition.

All PEPS vehicles getting the new fuel economy feature will automatically shut down your vehicle if leftidling unattended for an extended period of time.

The automatic engine idle shutdown feature will monitor the state of the vehicle to determine when the engine ispowered with no user interaction for an extended period of time. When this condition is detected, the vehiclewill inform the operator that a shutdown is imminent and, if the driver does not intervene, the engine will shutdown. Along with shutting down the engine, the ignition will be turned off to conserve vehicle battery power.To start the vehicle, press the brake and the start/stop button.

Customer Feedback

Feedback is provided during certain stages of the shutdown:

1. The message center will display a countdown timer 30 seconds prior to engine shutdown.

2. After the engine is shut down, a message will indicate the vehicle engine was shut down to save fuel economy.

Customer Shutdown Override

The customer can prevent the shutdown of the vehicle several ways:

1. The engine shutdown timer will be reset when a customer interaction is detected (For example, pressing thebrake or accelerator pedals).

2. At any point in the ignition on cycle, the customer can navigate to a menu selection to temporarily disable theshutdown feature for that ignition cycle. The menu selection will reset itself to enable the shutdown featureagain at the next ignition cycle.

NOTE: There is no user ability to permanently disable the shutdown.

3. During the countdown prior to the engine shutdown, the customer will be prompted to press the OK or RESETbutton (depending on level of message center) to temporarily disable the shutdown feature for that ignition cycle.


LESSON ONE LECTURE

Automatic Engine Idle Shutdown Preconditions

The Automatic Engine Idle Shutdown feature will monitor certain user inputs to determine the vehicle has beenleft in a state that is appropriate for disabling the engine. These inputs are intended to detect whether the user isintending to operate the vehicle.

They include:

• Engine Running (gas and diesel vehicles). Engine Running or Auto Stop Mode (hybrid and stop/start vehicles).

• Brake pedal not pressed.

• Accelerator pedal not pressed.

• Clutch pedal not pressed (manual transmission only).

• Vehicle speed low (below a threshold) to indicate the vehicle is not moving.

• Transmission in Park (automatic transmission only) or Neutral (manual transmission only).

• Power TakeOff (PTO) not active (if equipped).

• Emissions regeneration strategies are not active.

• Diagnostic test tool not connected to the vehicle.

Once these preconditions are met, a timeout will be started. When the predefined timeout period has been metthe automatic engine idle shutdown event will occur.


LESSON ONE LECTURE

Software Upgrades and Module Reprogramming

Types of module programming:

• Programmable Parameters

• Module Reprogramming (Flashing a Module)

• Programmable Module Installation (PMI)


LESSON ONE LECTURE

Module Programming and Reprogramming

When programming or reprogramming a module, use the following basic checks to make sure programmingcompletes without errors.

• Make sure the session is created Key On Engine Off (KOEO). Starting the vehicle before creating a sessionwill prevent some part number information from being inhaled by the IDS. This may prevent programmingof some modules.

• Make sure the 12 Volt battery is fully charged, or connected to the Rotunda® GR1190, before carrying out theprogramming steps. Connect the IDS to a power source.

• Inspect the VCM and cables for any damage. Make sure the scan tool connections remain connected throughoutprogramming.

• Do not use a wireless VCM during any type of module programming. (This is for VCM I only, VCM II can beused wirelessly).

• A hardwired internet connection is strongly recommended.

• Turn off all unnecessary accessories (ACM, heated seats, headlamps, all doors closed, interior lamps off,HVAC etc.).

• Disconnect any aftermarket accessories (remote start, alarm, power inverter, CB radio, etc.).

• Follow all onscreen instructions carefully, especially any key cycle movements the IDS directs you to perform.

• Disable the Microsoft® sleep mode, screensaver and hibernation modes on the IDS.


LESSON ONE LECTURE

Recovering a PCM/SJB when programming has resulted in a blanked module:

NEVER DELETE THE ORIGINAL SESSION!

1. Obtain the original IDS that was used when the programming error occurred during Module Reprogramming orProgrammable Module Installation (PMI).

2. Disconnect the VCM from the DLC and the IDS.

3. Reconnect the VCM to the IDS and then the DLC. Once reconnected the VCM icon should appear in the cornerof the IDS screen. If it does not, troubleshoot the IDS to VCM connection.

4. Starting with IDS release 71.01 and later, the IDS will highlight sessions with the failed programming in red.

NOTE: If the original session is not listed in the previous session list, click the Recycling bin icon at the lowerright of the previous sessions screen. This will load any deleted sessions and allow you to look through them.Double click to restore that session.

5. Once the session is loaded, the failed process should resume automatically.

6. If programming does not resume automatically, proceed to the Module Programming menu and select thepreviously attempted process, PMI or Module Reprogramming.

7. Follow all onscreen instructions to complete the programming process.

8. Near the end of programming, the IDS will prompt you to select certain parameters. It is important to make aselection for ALL parameters listed. If the correct selection is already highlighted, you must still click that selectionbefore clicking the Tick mark to complete the configuration.

9. The last screen on the IDS may list additional steps required to compete the programming process. Make sure thatall applicable steps listed on the screen are taken and in the order listed on the screen.


LESSON ONE LECTURE

Components that may need configuration after installation

Example:

• Rear view camera

Depending on the year and model the camera may be configured using:

• Scan tool

• Self configure after a period of time with the ignition on

Depending on the year and model of the vehicle, some components may not need to be configured.

Note: Gateway modules communicate on more than one network. This means they can pass the network testbut fail to communicate on another network. For example, a module that communicates with both HSCAN andMSCAN may only report out on HSCAN.

Note: Make sure that optional modules listed in the scan tool are actually equipped on the vehicle. One methodthat can be used to check is OASIS and review HVBoM.

Do all equipped modules show Pass?

Yes Go to HF2.

No Refer to 41800 Symptom Chart and perform the appropriate pinpoint test for a hard fault.


LESSON TWO LECTURE

HF2 PULL ALL CMDTCs

• Go to Self Test and select All CMDTCs.

• Erase codes and rerun test.

Note: Be aware that CMDTCs can be hard fault or memory (intermittent) codes. If an observable symptom ispresent (hard fault) but CMDTC does not return, the module’s predefined limits have not been exceeded.

Are there any CMDTCs present?

Yes If CMDTCs return or an observable symptom is present, Go to HF3.

If CMTDCs were present but do not return after being erased, Go to Intermittent Pinpoint Test.

No Go to HF3.

HF3 RUN ONDEMAND SELF TEST OF MODULE BASED ON SYMPTOM

• Run OnDemand Self Test for each module that reported a CMDTC or could be related to symptom (whenno codes are present).

Are there any ODDTCs present?

Yes Go to HF5.

No If CMDTCs were present, Go to HF4.

If no CMDTCs were present but there is an observable symptom, refer to the appropriate symptomchart(s).

HF4 ANALYZE CMDTCs

It is recommended to diagnose ODDTCs before CMDTCs.

• Determine which codes are relevant to the symptom

Note: Be careful when determining what codes are relevant.

• Do the codes involve modules related to the customer symptom?

• Based on code definition, could this cause the symptom?

Are all relevant codes from one module only?

Yes Go to HF6.

No Go to HF7.

HF5 DETERMINE IF RELEVANT ODDTC(S) ARE FROM ONEMODULE ORMULTIPLE MODULES

• Review relevant codes.

• Determine if codes are relevant to the symptom.

Note: Be careful when determining what codes are relevant




Yes Go to HF6.

No Go to HF7.


LESSON TWO LECTURE

HF6 ANALYZE CODES FROM ONE MODULE

• If there is one DTC, follow the appropriate pinpoint test.

• If multiple DTCs are present, review pinpoint tests to identify a potential common cause. If there is a potentialcommon cause, diagnose DTCs related to this first.

• If there is no apparent common cause, begin diagnosis with the first relevant DTC.

Was the cause of the concern found?

Yes Repair as necessary.

No Refer to Circuit Testing Diagnostic Aid when potential wiring concern may exist. If cause still cannotbe found, contact Technical Hotline with DTCs and symptom information.

HF7 ANALYZE CODES FROM MULTIPLE MODULES

Note: There can be a complex relationship when multiple modules are setting potentially related codes.

Taking the time up front and reviewing the interaction and looking for common items may help aid in diagnosisand save time in the end.

• Before any module is replaced, it is recommended to see if another related code would lead to the samecomponent

• Review pinpoint tests to identify a potential common cause. It is important to understand that all codesretrieved may not all be generated from a common source.

• When multiple modules are setting codes that appear to be related, there is usually one common cause. It isimportant to understand where messages originate and what modules receive a given message.

• If there is a potential common cause diagnose the first code of the module most related to the symptom.

• If there is no apparent common cause, begin diagnosis with the module most related to the symptom.



No Refer to Circuit Testing Diagnostic Aid when potential a wiring concern may exist. If cause still cannotbe found, Contact Technical Hotline with DTCs and symptom information.

INTERMITTENT MODULE OR NETWORK CONCERN

Pinpoint Test INT: Intermittent Module or Network Concern

Refer to Wiring Diagrams Cell 14, Module Communications Network for schematic and connector information.Normal Operation: Refer to the appropriate Workshop Manual sections for related systems

This pinpoint test is intended to diagnose the following:

• Wiring, terminals or connectors

• Inputs

• Outputs

• Modules

PINPOINT TEST INT: INTERMITTENT MODULE OR NETWORK CONCERN


• Request the customer complete the Customer Concern Identification Checklist or Write‐up Job Aid.• Attempt to verify concern (when test drive is not required).


• Perform quick visual inspection to identify obvious concern or aftermarket equipment.

• Refer to Circuit Testing pinpoint test for detailed testing information.

INT1 RUN NETWORK TEST

Note: Verification that optional modules are on the vehicle can be done by visual inspection, run OASIS andaccess the window sticker or search HVBoM by the base part number.

• Connect scan tool

• Establish vehicle session

• Run Network Test


Yes Go to INT2.

No If the module may be related to concern, refer to 41800 symptom chart and review appropriate pinpointtest for items that can cause this intermittent concern (hard fault was present at the time of this test butmay not be present during pinpoint test steps). If the module is not related to concern, Go to INT2.


LESSON TWO LECTURE

INT2 PULL ALL CMDTCs

Note: The presence of a CMDTC does not guarantee the fault currently exists.


• Record any reported code(s), including module and description.

Note: Screen prints can be done to capture information.


Were codes present?

Yes If code(s) return (hard fault), go to reporting module(s), run On Demand SelfTest and performappropriate pinpoint test.

If code(s) do not return (intermittent), Go to INT3.

No Go to INT22.

INT3 ATTEMPT TO DUPLICATE CONCERN

CMDTC codes that are erased and do not return indicate that fault is intermittent or that the module’s predefinedlimits have not been exceeded. For example, some codes are only set with ignition off or after a set amount oftime has elapsed.

• Attempt to duplicate the concern using the details provided by the customer about when the concern happens.

Was the concern duplicated?

Yes Go to INT4.

No Go to INT23.

INT4 PULL ALL CMDTCs AGAIN ANALYZE CODES


• Compare to previous codes to see what codes are the same.





Are relevant code(s) retrieved from one or more module(s) that are network related (missing messages,invalid network data or lost communication)?

Yes If the CMDTCs are UCodes, for lost communication or missing information, Go to INT14.

No Go to INT5.

INT5 DETERMINE IF CODE(S) ARE FROM ONE MODULE OR MULTIPLE MODULES

• Review relevant codes.

Are all relevant codes from one module?

Yes Go to INT6.

No Go to INT7.


LESSON TWO LECTURE

INT6 REVIEW POSSIBLE CAUSES: A WIRING CONCERN, AN INPUT OR OUTPUT, OR ACONCERN WITH THE MODULE

• Review the pinpoint tests for codes and the wiring diagrams for wires or components that could set the codes.

• Using an assistant, use the IDS datalogger feature to monitor PIDs during the road test and record the concern.If the concern is captured, analyze the recording by looking for abnormal fluctuations in PIDs. If the concernappears to be related to an input, attempt to induce concern using SGM function of IDS.



No Go to INT8.

INT7 LOOK FOR COMMON CAUSE

• When multiple modules are setting codes, there is often a common cause. CAN communication messagecharts in Workshop Manual sections 41800 and 41500 contain message information such as MessageDetails, network, sending and receiving modules. This can be important when trying to isolate the faultas an input/message, module or network concern.

• Review related pinpoint tests to look for shared inputs. Often an input is used by multiple modules. If an inputis suspected, proceed with careful inspection of all wiring prior to any component replacement.

• Inspect for damaged connectors.

• Loose pins.

• Unlocked terminals.

• Poor pin fit (use proper pin drag test).



No Go to INT8.

INT8 DETERMINE TYPE OF POTENTIAL WIRING FAULT

• Perform wiggle test and connector inspection to identify potential causes, such as poor pin fit.

• Note: Disconnecting connectors and wiggle testing wiring can sometimes temporarily correct the condition.Because of this, start by pulling on harness, then wiggle test and lastly, disconnect and inspect connectorsand pins. Use proper size test adapters from Rotunda Flex Probe Kit NUD105R025D, to check for pin fitwhen compared to other terminals in the connector.

• Wiring concerns can affect modules and networks in various ways.

Is a module logic power and ground circuit suspected?

Yes Go to INT9.

No For potential concerns with module communication circuits, Go to INT10.

For potential concerns with module input and output circuits, Go to INT11.


LESSON TWO LECTURE

INT9 CHECK MODULE LOGIC POWER AND GROUND CIRCUITS

• When there is an intermittent open in the module logic power circuit, the module stops operating almostimmediately and causes codes to set in other modules related to the missing information. If module PIDs arebeing viewed on IDS, they also flatline. Ground circuits faults may not show up as quickly and sometimeswill not show up until the module attempts to control an output. This is because ground may be shared formultiple circuits other than module logic.



No Go to INT12.

INT10 CHECK MODULE COMMUNICATION CIRCUITS

• Faults that exist for more than 5 seconds should set U codes for missing information in one or more modules.Faults lasting less than 5 seconds may not set codes. This depends on the network speed and length of fault. Amodule may be looking for information every 2 seconds and if the fault is present during this time, a DTCshould set. Using IDS Datalogger, multiple PIDs are likely to be affected. Depending on where the faultexists, one module may fail to communicate or multiple modules may be affected.



No Go to INT12.

INT11 CHECK MODULE INPUT AND OUTPUT CIRCUITS

• When a wiring concern exists related to an input or output, usually only one PID is affected and one code sets.The exception would be if other modules are relying on the input. Knowing the various types of wiring faultsthat can exist and the types of results that can be expected will be beneficial later if attempting to induce a fault.



No Go to INT12.

INT12 ATTEMPT TO INDUCE CIRCUIT FAULT

• WARNING: Never probe the electrical connectors on airbag, Safety Canopy® or side curtain assemblies.Failure to follow this instruction may result in the accidental deployment of these assemblies, which increasesthe risk of serious personal injury or death.

• For nonsupplemental restraints systems, attempting to induce a fault by creating an open or short by usinga fused jumper wire, may help isolate concern. Prior to creating any short, a careful review of the wiringdiagram must be done. The objective is to create a hard fault that matches the intermittent concern. If concernis duplicated, a targeted, thorough inspection can now be performed of the specific circuit or circuits thatcould be causing concern.



No Go to INT13.


LESSON TWO LECTURE

INT13 INSTALL TEMPORARY OVERLAY

• Temporarily overlay suspected circuit.

Was cause of concern resolved?

Yes Repair wiring using the least disruptive method. This may include a permanent overlay of the circuitwhen replacing circuit would involve significant vehicle disassembly.

No Take the appropriate next step from the list below:

• Contact the Technical Hotline with codes and symptom information,

• Release the vehicle back to customer with flight recorder

• Release the vehicle as No Problem Found. Refer to NPF Diagnosis and NPF Technician Checklist

• Replace the suspected input, output or module.

Note: Any component replacement at this time needs to be clearly documented as to what steps weretaken prior to this action.

INT14 ANALYZE U CODES

The root cause of intermittent network codes are usually caused by:

• an open or short in the twisted pair of communication wires for the associated network

• a high or low battery voltage

• a defective module

Note: Some network messages are shared between networks and therefore there may be codes in modulesfrom more than one network.

• Determine if all modules on a network are reporting intermittent lost communication. This would indicate asustained wiring or voltage concern. There can be situations where not all modules on a network report lostcommunication. Modules only monitor the health of modules they depend on to implement their feature.For example, the seat module does not need anything from the steering column module and will not set acode if that module drops off the network. Also, depending on the length of time the fault is present, somemodules may not have had time to flag a concern. Also, a module’s tolerance to voltage issues may vary.Lower than or higher than normal voltages may cause some modules on a network to lose communicationbefore other modules.

Are multiple modules reporting intermittent lost communication or missing information?

Yes Go to INT15.

No Go to INT20.

INT15 MONITOR VOLTAGE AT DLC

When diagnosing a suspected network wiring concern, a DMM or oscilloscope can be used to monitor voltageat the DLC on the suspected network. Normal voltages would range between 0.5 and 4.5 volts, depending onnetwork messages being sent.

Is the voltage between 0.5 and 4 volts during fault?

Yes Go to INT16.

No If voltage is above 3.5 volts, attempt to locate intermittent short to power, 12 volts or VRef 5 volts.

If voltage is less than 1.5 volts and not 0 volts, attempt to locate intermittent short to ground.

If voltage is 0 volts, attempt to locate intermittent open.


LESSON TWO LECTURE

INT16 CHECK FOR CAN+ AND CAN – SHORT TOGETHER

If CAN+ and CAN‐ short together, the voltage will be 2.5 volts (regulated value). This can be difficult to identifybecause the at rest voltages, (no messages being transmitted), is also approximately 2.5 volts. On MSCANnetwork it may be even harder to find due to MSCAN circuits have more at rest time than HSCAN. By using anoscilloscope you can identify the slight difference between normal at rest voltage and a short together.

Is a CAN+ and CAN – short together suspected?

Yes Attempt to locate source of intermittent short.

No Go to INT17.

INT17 CHECK FOR ONE MODULE TAKING DOWN NETWORK

• When analyzing codes, one thing to look for is a module concern that takes down a network. One sign of thisis one module on the network does not set lost communication codes and all other modules do. This can bebecause this is the module that is causing the concern.

• In the case of a gateway module, multiple networks may go down. The root cause of a module causing thisconcern can be an output ground concern of the module.

• A poor ground can cause module communication trouble, including blocking all network traffic.

Is one module suspected of taking down the network?

Yes Remove fuse or disconnect the suspected module and confirm the concern is no longer present. Replacemodule.

No Go to INT18.

INT18 ATTEMPT TO INDUCE CIRCUIT FAULT, MODULE LOGIC POWER OR GROUND

• WARNING: Never probe the electrical connectors on airbag, Safety Canopy® or side curtain assemblies.Failure to follow this instruction may result in the accidental deployment of these assemblies, which increasesthe risk of serious personal injury or death.

• For nonsupplemental restraints systems, attempting to induce a fault by creating an open or short by usinga fused jumper wire, may help isolate concern. Prior to creating any short, a careful review of the wiringdiagram must be done. The objective is to create a hard fault that matches the intermittent concern. If concernis duplicated, a targeted, thorough inspection can now be performed of the specific circuit or circuits thatcould be causing concern.



No Go to INT19.


LESSON TWO LECTURE

INT19 INSTALL A TEMPORARY OVERLAY



Yes Repair wiring using least disruptive method. This may include a permanent overlay of circuit whenreplacing circuit would involve significant vehicle disassembly.

No Take appropriate next step from the list below:

• Contact the Technical Hotline with code(s) and symptom information.

• Release the vehicle back to the customer with flight recorder.

• Release the vehicle as No Problem Found. Refer to NPF Diagnosis and NPF Technician Checklist



INT20 IDENTIFY SOURCE OF LOSS OF COMMUNICATION OR MISSING INFORMATION

• CAN communication message charts in Workshop Manual section 41800 and 41500 contain messageinformation such as Message Details, network, sending and receiving modules. This can be important whentrying to isolate the fault as missing information.

• Use IDS Datalogger to monitor PIDs that are reported as missing and look for potential in range faults. This isa fault that is not recognized by primary module, but another secondary module may set a code.

Does IDS Datalogger indicate a potential in range fault?

Yes Repair input as appropriate.

No Go to INT21.

INT21 CHECK FOR OPEN IN CAN + OR CAN TO MODULE

• If an open occurs in the CAN wiring to a module, only that module may set codes. This depends on when thefault occurs and what messages are sent and received by the module.


Was the concern resolved?

Yes Repair wiring using the least disruptive method. This may include a permanent overlay of circuit whenreplacing the circuit would involve significant vehicle disassembly.

No Take the appropriate next step from the list below:

• Contact the Technical Hotline with code(s) and symptom information.

• Release the vehicle back to the customer with flight recorder.

• Release the vehicle as No Problem Found.




LESSON TWO LECTURE


• Attempt to duplicate the concern using the details provided by the customer about when the concern happens.


Yes Go to INT24.

No Go to INT23.

INT23 OBTAIN ADDITIONAL INFORMATION

• If the concern cannot be duplicated, determine if additional condition details may aid in duplicating theconcern. If the original writeup was power windows do not work, details such as which direction, roadconditions and temperature may be valuable.

Was the concern able to be duplicated with additional information?

Yes Go to INT25.

No Contact the Technical Hotline with code(s) and symptom information, release the vehicle back to thecustomer with a flight recorder and/or release vehicle as No Problem Found.

INT24 REVIEW SYMPTOM CHART

• Review the appropriate pinpoint test for the system, check for possible causes and check all wiring andconnectors.



No Use the IDS scan tool Datalogger for the related system to check for in range faults.

INT25 REVIEW PINPOINT TESTS RELATED TO CMDTCs

• Review pinpoint tests to determine related circuits to perform an inspection or wiggle tests.

• Try to induce the fault.



No Contact the Technical Hotline with code(s) and symptom information.

Intermittent Diagnosis using IDS Oscilloscope

The IDS Oscilloscope

The IDS oscilloscope has three different setups that may be used. They are:

• Auto CAN

• Manual

• Manual with One Shot Trigger

All three use two channels to monitor the suspect network circuits. Each setup has advantages and disadvantages

Before you can use any of these setups you must connect the IDS to the vehicle. Once connected make thefollowing selections:

1. Choose the tool box tab.

2. Oscilloscope tools.

3. Oscilloscope.

4. Click the blue tick.

5. Follow the instructions for connecting the VMM to the IDS.



Auto CAN

Auto CAN traces for both data (+) and data () are taken simultaneously (2channel). While this is the easiest to setup and can be used to monitor basic network operation, there are two reasons this may not be adequate. First, theAuto CAN setup only shows the pattern, not the DC voltage. Second, depending on the length of the intermittentfault, the concern may be difficult to see on the screen.

Make the following selections to set up the oscilloscope for Auto CAN:

1. Click on Channel 1.

2. Click on Auto.

3. Choose CAN (+).

4. Close Channel 1.


6. Click on Auto.

7. Choose CAN ().

8. Close Channel 2.

9. Click on the little red man to begin recording.



Manual mode

Due to the limitations of the Auto CAN set up, it is generally recommended to use the Manual setup so the scopecan be changed from AC to DC. Using the manual set up allows DC voltage to be determined, but requires moresetup time.

Make the following selections to set up the oscilloscope for Manual mode:


2. Click on Manual.

3. Choose Sense.

4. Choose Red Probe.

5. Choose Scale.

6. Choose 1v/ div.

7. Choose Coupling DC.

8. Filter, Invert and Display remain at default.

9. Close Channel 1.


11. Click on Manual.

12. Choose Sense.

13. Choose Black Probe.

14. Choose Scale.

15. Choose 1v/ div.

16. Choose Coupling DC.

17. Filter, Invert and Display remain at default.

18. Close Channel 2.

19. Click on Time Base.

20. Click on Scale.

21. Choose 20 µs/ div.

22. Close Time Base.

23. Click on the little red man to begin recording.



Manual with One Shot Trigger

One Shot Trigger can capture a quick, intermittent fault, but does not show a pattern until a predetermined targetis exceeded. This set up is used to capture an intermittent fault that does not occur often and occurs briefly. Itdoes require more set up time.

After completing the Manual mode set up, make the following selections to set up the oscilloscope for One ShotTrigger:

1. Click on Trigger.

2. Set Source to Channel 1.

3. Click on Edge.

4. Select Rising or Falling.

Select Rising if you are trying to capture a voltage increase such as a short to voltage.

Select Falling if you are trying to capture a voltage decrease such as short to ground.

5. Click on Mode.

6. Choose One Shot.

7. Close Trigger.

At this point you will need to set the position of the trigger on the screen. In the lower right you need to selectthe trigger button. You would then move to the upper left to move the vertical trigger position up or down. Thisis accomplished by using the arrows. The double arrow moves it quickly and the single arrow moves it slowly.

8. Click on the little red man to begin recording

____________________________________________________________________________________________________________________________________________

5. Based on your results what network appears to have the concern? Why?

____________________________________________________________________________________________________________________________________________

•

INT14 ANALYZE U CODES

The root cause of intermittent network codes are usually caused by:

• an open or short in the twisted pair of communication wires for the associated network

• a high or low battery voltage

• a defective module

Note: Some network messages are shared between networks and therefore there may be codes in modulesfrom more than one network.

• Determine if all modules on a network are reporting intermittent lost communication. This would indicatea sustained wiring or voltage concern. There can be situations where not all modules on a network reportlost communication. Modules only monitor the health of modules they depend on to implement theirfeature. For example, the seat module does not need anything from the steering column module and willnot set a code if that module drops off the network. Also, depending on the length of time the fault ispresent, some modules may not have had time to flag a concern. Also, a module’s tolerance to voltageissues may vary. Lower or higher than normal voltages may cause some modules on a network to losecommunication before other modules.

Are multiple modules reporting intermittent lost communication or missing information?

Yes Go to INT15.

No Go to INT20.




____________________________________________________________________________________________________________________________________________

•

INT15 MONITOR VOLTAGE AT DLC

When diagnosing a suspected network wiring concern, a DMM or oscilloscope can be used to monitor voltageat the DLC on the suspected network. Normal voltages would range between 0.5 and 4.5 volts, depending onnetwork messages being sent.

Is the voltage between 0.5 and 4 volts during fault?

Yes Go to INT16.

No If voltage is above 3.5 volts, attempt to locate intermittent short to power, 12 volts or VRef 5 volts.

If voltage is less than 1.5 volts and not 0 volts, attempt to locate intermittent short to ground.

If voltage is 0 volts, attempt to locate intermittent open.

• Perform step INT15 using the Auto CAN, Manual and One Shot modes of the oscilloscope on the IDS.Also view the voltages using the DMM.

• Review the Workshop Manual section 418–00 Diagnosis and Testing Principles of Operation forexamples of oscilloscope patterns.

NOTE: If you are using a DMM to measure the voltage at the DLC. You will need to check each circuitindividually to ground.

7. What do your results indicate?

APPENDIX

Principles of OperationBoth the High Speed Controller Area Network (HSCAN) and the Medium Speed Controller Area Network(MSCAN) use an unshielded twistedpair cable of data (+) and data () circuits. The HSCAN operates at amaximum data transfer speed of 500 Kbps and is designed for real time information transfer and control. TheMSCAN operates at a maximum data transfer speed of 125 Kbps for bus messages and is designed for generalinformation transfer.

Controller Area Network (CAN) Fault ToleranceNOTE: The oscilloscope traces below are from the Integrated Diagnostic System (IDS) oscilloscope taken usingthe IDS preconfigured Controller Area Network (CAN) settings. The traces are for both data (+) and data () takensimultaneously (2channel) at a sample rate of 1 megasample per second (1MS/s) or greater.

Traces below are viewed at 500mV per division (vertical axis) and 20 microseconds (20μs) per division (horizontalaxis). Readings taken with a different oscilloscope vary from those shown. Compare any suspect readings toa known good vehicle.

Normal CAN Operation

The data (+) and data () circuits are each regulated to approximately 2.5 volts during neutral or rested networktraffic. As messages are sent on the data (+) circuit, voltage is increased by approximately 1.0 volt. Inversely, thedata () circuit is reduced by approximately 1.0 volt when a message is sent.

Successful communication of a message can usually be identified by the slight spike at the end of a messagetransmission. Any signals that are significantly different than the normal CAN waveform may cause network DTCs(Ucodes) to set or may cause a complete network outage.


APPENDIX

CAN Circuits Shorted Together

In the event that the data (+) and data () circuits become shorted together, the signal stays at base voltage (2.5V)continuously and all communication capabilities are lost.

CAN (+) Circuit Shorted To Ground

In the event that the data (+) circuit becomes shorted to ground, both the data (+) and data () circuits are pulledlow (0V) and all communication capabilities are lost.


APPENDIX

CAN () Circuit Shorted To Ground

In the event that the data () circuit becomes shorted to ground, the data () circuit is pulled low (0V) and the data(+) circuit reaches nearnormal peak voltage (3.0V) during communication but falls to 0V instead of normal basevoltage (2.5V). Communication may continue but at a degraded level.

CAN (+) Circuit Shorted To Battery Voltage

In the event that the data (+) circuit becomes shorted to battery voltage, the data (+) circuit is pulled high (12V) andthe data () circuit falls to abnormally high voltage (above 5V) during communication and reaches battery voltage(12V) for peak voltage. Communication may continue but at a degraded level.


APPENDIX

CAN () Circuit Shorted To Battery Voltage

In the event that the data () circuit becomes shorted to battery voltage, both the data (+) and data () circuits arepulled high (12V) and all communication capabilities are lost.

CAN Circuit Signal Corruption

Rhythmic oscillations, inductive spikes or random interference can disrupt the network communications. Thecorruption signal source may be outside electrical interference such as motors or solenoids or internal interferencegenerated from a module on the network. In some cases, an open in either the data (+) or data () circuit to a networkmodule may cause the module to emit interference on the one circuit which is still connected. The trace shown is anexample of a "sawtooth" pattern transmitted from a module with one open network circuit.

Other corruptions may be present when a module is intermittently powered up and down. The module on power upmay initiate communication out of sync with other modules on the network causing momentary communicationoutages.
