B1203-SRS WARNING INDICATOR CIRCUIT/PERFORMANCE


B1203-SRS WARNING INDICATOR CIRCUIT/PERFORMANCE (CONTINUED)For a complete wiring diagram Refer to Section 8W.

When Monitored:With the ignition on, the Occupant Restraint Controller (ORC) monitors the CAN B bus for a message from theInstrument Cluster containing the airbag warning indicator status. The ORC requests the warning lamp statusfrom the Instrument Cluster once every second.

Set Condition:This DTC will set immediately if the indicator status is LOW or HIGH.

Possible CausesINSTRUMENT CLUSTER ACTIVE DTCsORC

Diagnostic Test

1. CHECK FOR AN ACTIVE DTCNOTE: Ensure the battery is fully charged.NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery mustbe disconnected.Turn the ignition on, then off, and then on again.With the scan tool, read ORC DTCs.

Select DTC type.Active

Go To 2Stored

Go To 4

2. CHECK FOR INSTRUMENT CLUSTER DTCsWith the scan tool, read Instrument Cluster DTCs.

Does the scan tool display any Instrument Cluster DTCs?Yes >> Refer to the symptom list for problems related to the Instrument Cluster.

Perform the ORC VERIFICATION TEST-VER 1. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNO-SIS AND TESTING)

No >> Go To 3

3. REPLACE THE ORCWARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-utes before proceeding.WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure totake the proper precautions can result in accidental airbag deployment and personal injury or death.

RepairReplace the ORC in accordance with the service information.Perform the ORC VERIFICATION TEST-VER 1. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNO-SIS AND TESTING)


B1203-SRS WARNING INDICATOR CIRCUIT/PERFORMANCE (CONTINUED)4. TEST FOR INTERMITTENT CONDITIONWith the scan tool, record and erase all DTCs from all Airbag modules.If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-utes before proceeding.Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.Look for chaffed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, orcontaminated terminals.The following additional checks may assist you in identifying a possible intermittent problem.Reconnect any disconnected components and harness connector.WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.With the scan tool, monitor active codes as you work through the following steps.WARNING: To avoid personal injury or death, maintain a safe distance from all airbags while performing thefollowing steps.Wiggle the wiring harness and connectors of the related airbag circuit or component.If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.If only stored codes return, continue the test until the problem area has been isolated.In the previous steps you have attempted to recreate the conditions responsible for setting the active DTC in ques-tion.

Does the scan tool display any ACTIVE DTCs?Yes >> Select the appropriate diagnostic procedure from the Table of Contents in this section.No >> No problem found at this time. Erase all codes before returning vehicle to customer.

2. CHECK FOR ACTIVE DTC B1204 PASSENGER AIRBAG INDICATOR CIRCUIT LOW WITH SWITCH BANKCONNECTOR DISCONNECTED

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two min-utes before proceeding.Disconnect the Switch Bank connector.NOTE: Check connectors - Clean and repair as necessary.WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.With the scan tool, erase ORC DTCs.Turn the ignition off, wait 10 seconds, and then turn the ignition on.With the scan tool, read ORC DTCs.

Does the scan tool display active: B1204 PASSENGER AIRBAG INDICATOR CIRCUIT LOW?Yes >> Go To 3No >> Replace the Passenger Airbag On/Off Indicator Lamp in accordance with the Service Information.

Perform ORC VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNOSISAND TESTING)


B1204-PASSENGER AIRBAG INDICATOR CIRCUIT LOW (CONTINUED)3. CHECK (G104) PASSENGER AIRBAG INDICATOR DRIVER CIRCUIT FOR A SHORT TO GROUNDWARNING: If the Occupant Restraint Controller (ORC) is droppedat any time, it must be replaced. Failure to take the proper pre-cautions can result in accidental airbag deployment and personalinjury or death.WARNING: To avoid personal injury or death, turn the ignition off,disconnect the battery and wait two minutes before proceeding.Disconnect the ORC C2 connector.NOTE: Check connectors - Clean and repair as necessary.Connect the appropriate Load Tool ORC Adaptor to the ORC connec-tor.Measure the resistance of the (G104) Passenger Airbag IndicatorDriver circuit between ground and the ORC Adaptor.

Is the resistance below 100.0 ohms?Yes >> Repair the (G104) Passenger Airbag Indicator Driver cir-

cuit for a short to ground.Perform ORC VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/RESTRAINTS - DIAGNOSISAND TESTING)
