1.3 Body electrical control functions 1.3.1 Door lock control (a) Power door lock When a lock/unlock signal is input from the driver's door key lock switch or the door lock manual switch, the BCM operates the front and rear door lock motors at the same time to lock or unlock the doors. (b) Keyless entry (vehicles without keyless start system) Keyless entry system consists of a BCM, transmitter, keyless entry receiver, door switches and door lock actuators (door lock assemblies). When the Lock or Unlock button of the transmitter is pressed, the transmitter sends a Lock or Unlock signal to the keyless entry receiver. A Lock or Unlock signal is sent to BCM from keyless entry receiver and then BCM verifies if the received signal agrees with the registered code. When BCM judges their agreement, it actuates each door lock actuator so that all door locks are locked or unlocked. Also, when the door lock is locked or unlocked via transmitter, BCM controls answers back using the hazard warning light and dome light. Note that both the following conditions must be satisfied. - Key is removed from the ignition switch - All doors are closed

The BCM receives the lock and unlock signals from the keyless entry receiver. (Refer to current service manuals for the location of the keyless entry receiver in other Suzuki models)

Figure 2: Door lock control diagram

Figure 3: Location of keyless entry receiver (1) (Suzuki Alto/Celerio)


(c) Door lock safety function The doors cannot be locked or unlocked with the keyless transmitter under the following conditions. - Key switch is ON (key is inserted into the ignition switch) - A door is open (d) Timer lock function If a door is not opened within 30 seconds after unlock operation was done by keyless entry transmitter, keyless start remote controller or door request switch, doors are automatically locked again. (e) Keyless entry registration In the keyless entry system, transmitters ID codes are also registered and stored in the BCM. The number of transmitters that can be registered at any once time depend upon the model of the vehicle. (f) Door lock cancellation function for airbag deployment When the BCM receives an airbag deployment signal from the airbag controller, it operates all the door lock motors to unlock the doors.

1.3.2 Trunk lid control function When an ON signal from the back door opener switch is input while the doors are unlocked after an unlock signal was output by the BCM, the BCM operates the back door opener motor to open the latch of the back door. The back door or trunk lid can also be opened by using the trunk release button in the instrument panel (if equipped) or by use of the trunk release button on the transmitter key.

Figure 4: Back door opener switch (1) (Suzuki Swift)


1.3.3 Interior light control When the interior lamp switch is at the DOOR position, the BCM judges the condition of each door switch and turns the room lamp on or off. a) ON conditions Any of the following conditions. A door is open Keyless entry (door request switch) is used to unlock the

doors Keyless entry (door request switch) is used to lock the doors

(when answer back is set to room lamp flashing)

b) Dimming OFF conditions Any of the following conditions. About 15 seconds pass after closing all the doors Room lamp flashing for the keyless (keyless start) answer

back is completed. Key or keyless entry (door request switch) is used to lock

the doors (when answer back is set to hazard lamp flashing)

Battery protection function operates

Figure 5: Interior light unit (Suzuki Kizashi A6B424)

Battery protection function When about 15 minutes have passed after the room lamp and door ajar warning lamp in the combination meter turn on because one of the doors is open, the BCM dims and then turns off the room lamp and turns off the door ajar warning lamp. This prevents the battery from running down and reduces power consumption.


1.3.4 Rear Wiper control When the ignition switch is ON, the BCM judges the condition of the rear wiper and washer switch and turns the rear wiper relay ON or OFF. This switches the rear wiper between continuous operation, intermittent operation and off. 1) Continuous operation When rear wiper and washer switch ON or ON + WASH is input to the BCM, the BCM turns ON the rear wiper relay. It keeps ON the rear wiper relay to continuously operate the rear wiper motor until the rear wiper and washer switch is turned to OFF, INT or WASH. 2) Intermittent operation When rear wiper and washer switch INT is input to the BCM, the BCM turns ON the rear wiper relay for about 1 second and then OFF for about 7 seconds. In this way, the rear wiper motor is operated intermittently in intervals of about 8 seconds. Ignition switch Rear wiper and Washer switch BCM Rear wiper Relay output

1.3.5 Warning buzzer control The BCM judges the signals from the key switch, driver's door switch, lighting switch, speed sensor, shift switch (AT vehicles only), or the warning buzzer request signal from the keyless start controller. When all the following conditions are satisfied, the warning buzzer in the BCM sounds when: 1) Key reminder warning - Ignition switch is OFF - Key is inserted into the ignition switch - The driver's door is open 2) Light reminder warning - Lighting switch is in the small or ON position - Key is removed from the ignition switch - The driver's door is open 3) Reverse warning (AT vehicles only) - Ignition switch is ON - Selector position is "R 4) Parking brake reminder warning - Activated when parking brake engaged and vehicle speed is greater than 7km/h. Deactivated at speed below 3km/h. 1.3.6 Exterior lamp control a) Turn signal indicator lamps BCM monitors conditions of the turn signal switch or the hazard warning switch. When turn signal switch or hazard warning switch is turned ON, BCM operates the turn signal lights. The BCM also transmits the turn signal switch signal and turn signal buzzer request signal to the combination meter.


When turn signal switch is at ON position, the BCM monitors turn signal light bulb circuit. In the case where a fault exists in the turn signal circuit, the BCM controls turn signal light, turn signal indicator (also indicator in combination meter) and buzzer as follows. b) Setting the turn signal indicator For situations such as lane changes, it is possible to set the number of times the turn signal lights flash when turn signal switch is momentarily switched on and off. This setting can be selected using the SDT. The following setting options are available: 0: Turn signal lights flash once when turn signal switch is

turned on 1 time. +1: Turn signal lights flash 2 times when turn signal switch is

turned on 1 time. (+1 time on and off for 1 time switching on)

+2: Turn signal lights flash 3 times when turn signal switch is turned on 1 time. (+2 time on and off for 1 time switching on)

+3: Turn signal lights flash 4 times when turn signal switch is turned on 1 time. (+3 time on and off for 1 time switching on

c) Tail light control In some Suzuki models, the BCM also controls the operation of the tail lights. The BCM monitors lighting switch position. BCM turns ON/OFF the tail lamp relay according to the lighting switch position, in order to turn ON/OFF the following lamps: - Position lamps - Tail lamps - License lamp d) Fog lamps BCM turns ON/OFF the fog lamp relay according to lighting switch and fog lamp switch, in order to turn ON/OFF the fog lamps and fog lamp indicator.

The passenger seat sensor is integrated in the seat

cushion and the seat cushion must be replaced in case of a faulty passenger seat sensor.

When checking passenger seat belt SW on Data List in SDT, seat yourself on the passenger seat to turn on the item 31a

1.3.8 Shift lock control (A/T transmission) In automatic transmissions, the BCM also controls the shift lock function. When the shift lever is in the P position, the shift lock solenoid locks it in position to prevent unintended shift from the P position. In order to sift the selector lever out of the P position, the following inputs are used by the BCM:

: CAN bus


1.3.9 Security alarm control The BCM also controls the operation of the security alarm. The following components are the input of the BCM for alarm control: RF door ajar switch LF door ajar switch RR door ajar switch LR door ajar switch Bonnet switch (when equipped) Trunk lid switch (when equipped) Remote transmitter key Ignition switch The following outputs are then controlled by the BCM based on the status of the inputs. Security indicator light Horn Indicator lights Buzzer

Operation When the vehicle is locked using the transmitter key, the BCM actuates all door locks to lock all doors. NB: the BCM does not actuate the door lock mechanisms or activate the alarm in cases where the lock button of the transmitter is pressed and one of the doors is not closed.

Figure 7: Security alarm indicator light or Theft deterrent light (1) (Suzuki Swift AZH series)

When all lock conditions are met and the doors are locked, the BCM not activates the security warning indicator lamp. The indicator lamp flashes fast for about 20 seconds. During this time, the security alarm is not activated and the doors can still be opened without activating the alarm. After the 20 seconds, the security alarm starts flashing slowly. This is an indication that the security alarm is active. Security alarm mode selection The status of the security alarm can be changed from active to inactive and vice versa. When it is set to active, the security alarm function operates as described above. When it is set to inactive, the BCM switches OFF all security alarm functions. The security alarm mode selection can be selected using the SDT or by following the procedure below.


1) Confirm that all doors are closed, all doors are unlocked and lighting switch OFF position. 2) Set ignition ON. 3) Perform the following steps within 15 seconds. a) Turn lighting switch to CLEARANCE position. b) Turn lighting switch to OFF position. c) Repeat Step a) and b) 3 times. d) Operate driver door lock knob (1) to LOCK position. e) Operate driver door lock knob to UNLOCK position. f) Repeat Step d) and e) once. g) Operate driver door lock knob to LOCK position.

Figure 8: Door lock knob (1) (Suzuki Swift AZH)

1.4 BCM monitoring functions The BCM also has monitoring functions. It monitors certain parameters such as alternator charge condition, outside air temperature, etc. This information is used by other control modules in the vehicle. 1.4.1 Monitoring of ambient air temperature The ambient air temperature is connected to the BCM and sends a voltage signal to the BCM. The BCM uses this voltage signal to calculate the temperature of the ambient air. This information is used by control modules such as the HVAC control module and the combination meter.

1.5 BCM diagnostic information

1.5.1 BCM self diagnostic information Description BCM monitors conditions of system components and its circuit when ignition is in ON. When an abnormality in the system occurs, BCM performs controls as follows. Self-Diagnosis Function When an abnormality in the system occurs, the area where that abnormality lies is stored in the memory of EEPROM in BCM. Fail-Safe Control When any of the following DTCs is detected, BCM enters fail-safe mode as long as malfunction continues, but that mode is canceled when BCM recovers normal condition. Monitored condition : CAN bus

1.4.2 Monitoring of A/C evaporator temperature The BCM monitors the temperature of the evaporator by use of a temperature sensor installed on the evaporator. The information on the evaporator temperature sensor is used to control operation of the A/C compressor. The sensor is connected to the BCM in the same way as the ambient temperature sensor (figure 9)

Lesson 2 Door locks & keyless entry

Learning outcomes The contents of this chapter will enable learners to: Describe the structure of the door lock function of the BCM. Describe the functions of the different components of the

door lock and keyless entry system.


2.1 Overview The door locks are mechanisms that electronically lock and unlock the front doors, rear doors and back door. When the driver's door lock switch that is linked to the driver's door lock knob is set to the lock side, all the door lock motors operate to lock the latches. When the switch is set to the unlock side, all the door lock motors operate to unlock the latches. In keyless entry, the door lock mechanisms operate when the BCM controller receives a signal from the transmitter.

2.2 Structure and operation 2.2.1 Components Power door lock system consists of: BCM, Door lock actuators and Power window master switch. The power door lock system is controlled by the BCM. Door lock actuators are integrated into door lock assembly (1), figure 1. Front door lock assembly also integrates the door lock switch. Door lock actuators are all covered for anti theft purpose.

The BCM controller analyzes the signals from the driver's door lock switch, the other door switches, the key switch and the keyless entry (transmitter). It actuates the door lock motors to lock or unlock the doors. 2.2.2 Parts functions 2.2.2.1 Drivers door lock switch This switch has 2 contact points (lock - unlock) that are linked to the driver's door lock knob.

Figure 1: Door lock actuator (1)


2.2.2.2 Door lock motor A door lock motor is installed inside each door. The polarity of the current that is output from the body electrical (door lock) controller is changed to switch the motor rotation between lock and unlock.

2.2.2.3 Transmitter unit A transmitter unit is installed in the key. It transmits a radio wave when the transmit button is pressed. 2.2.2.4 Key switch This switch is installed in the key cylinder. It detects whether or not the key is inserted in the key cylinder. The BCM prohibits operation of the power door lock via the transmitter unit whenever a key is in the ignition key cylinder.

2.3 Power door lock operation The driver's door lock switch (1) inputs the signal into the input circuit (2) of BCM. The signal is processed in the control circuit (3) and amplified in the output circuit (4). It then actuates the door lock motors (5) to lock or unlock the doors.

2.4 Keyless entry operation The radio wave that is transmitted from the transmitter (1) is received by the antenna that is built in to the keyless receiver (2). The security code is verified and an operation command signal is generated. The signal is processed in the control circuit (3) and amplified in the output circuit (4). It then actuates the door lock motors (5) to lock or unlock the doors.

2.5 Keyless entry safety function The keyless entry safety function prevents the doors from being locked or unlocked using keyless entry while the key is inserted in the key cylinder, or while a door is open. There is also a timer lock function that automatically locks the doors if a door is not opened within 30 seconds of unlocking the doors using keyless entry. The timer lock function does not operate if a door is opened within 30 seconds of unlocking, the key is inserted, or the doors are locked using the driver's door lock switch.

2.6 Answer back function When the doors are locked or unlocked using keyless entry, the answer back function is activated to confirm the operation. When the doors are locked, the hazard lamps flash once and when the doors are unlocked, the hazard lamps flash twice. The following procedure can be used to change the answer back function from hazard lamp flashes to room lamp flashes, or from room lamp flashes to hazard lamp flashes.


Lesson 3 Keyless start system

Learning outcomes The contents of this chapter will enable learners to: Name the inputs and outputs of the keyless start system. Describe the functions of the keyless start system Describe the functions of each of the components

connected to the keyless start system Describe the communication process of the keyless start

control module and its components during door unlocking/locking operation.

Describe the communication process of the keyless start control module and its components during engine start operation.

Explain the different fail safe operation strategies the keyless start control module employs when there is a malfunction in the system or its components.

Describe the remote controller registration process for each of the vehicles equipped with the keyless start system.


3.1 Overview of keyless start system With the keyless start system, the driver simply carries the

keyless start remote control. The system has a door lock function where a door is locked or unlocked by pressing the door's request switch, and an engine start function where the engine starts without having to insert a key into the ignition switch. The system is also equipped with a normal keyless entry function, where the lock or unlock button on the keyless start remote control can be pressed to lock or unlock the doors.

The keyless start system uses radio waves. It verifies the security code using 2-way communication between the keyless start remote control and the keyless start controller.

An antenna for receiving the security code is built in to the keyless start controller. An interior antenna and luggage antenna for communicating inside the vehicle are installed in the center console and luggage compartment. Door antennas for communicating outside the vehicle are installed in the rear bumper and the outer handles of the driver's and front passenger's doors.

The keyless start remote control is equipped with an indicator lamp for confirming operations (or that the battery has run down). The indicator lamp turns on when there is a transmission from the keyless start remote control.

3.2 Structure and operation 3.2.1 Components The keyless start system is made up of a Keyless controller, Steering lock unit, Antennas (driver's door, front passenger's door, back door,

interior, luggage), Door request switches (driver's seat, front passenger's seat,

back door), Engine start knob and Keyless start indicator in the combination meter.

3.2.2 Functions of components 1) Keyless start controller This controller is installed in the instrument panel unit and uses CAN communication to exchange information with parts such as the BCM, ECM and combination meter. The controller monitors the condition of the door request switches, door switches and engine start knob. It uses this information to lock and unlock the doors and start the engine.


Keyless Start Control module Input/output diagram


2) Keyless start remote control This remote control receives request signals from the various antennas and transmits the security code to the antenna that is built in to the keyless start controller. It is equipped with an indicator lamp for confirming operations (or that the battery has run down), lock and unlock buttons for operating the keyless entry function, and a mechanical key that can be used to lock or unlock the doors and start the engine when the keyless start system will not operate, such as when the battery has run down.

3) Steering lock unit This unit is installed on the steering column. When power is supplied to the solenoid by the engine start knob release signal from the keyless start controller, the lock pin is pulled up, enabling the holder. This means that the engine start knob can be rotated. However, note that if the engine start knob continues to be pressed for longer than 5 seconds, power supply is prohibited to prevent the solenoid from generating heat. .

4) Engine start knob This knob is installed on the steering lock unit. When the engine start knob is pressed, the internal switch (push switch) turns ON and transmits an ON signal to the keyless start controller.

5) Engine push start switch The push start switch is installed in the instrument panel. It is also equipped with a transceiver coil that enables communication to the transponder in the remote controller when the remote controller is used to start the engine. 6) Driver's door, front passenger's door and back door request switches These switches are installed on the door outer handles. The keyless start controller monitors the condition of the door request switches. When a door request switch is turned ON, it locks or unlocks the door depending on the door lock condition at that time. 7) Door lock switch The door lock switch is built in to the door lock assembly. It monitors the lock condition of the driver's door and the front passenger's door. It is OFF when the doors are locked and ON when they are unlocked.

3.3 Keyless start system door lock/unlock function When a door request switch that is located in the driver's door knob, front passenger's door knob or back door knob is pressed (5), the keyless start controller activates the interior antenna (10) and luggage antenna (9) to perform communication inside the vehicle. When it is judged that the keyless start remote control is not inside the vehicle, the door antenna (6) on the door whose door request switch was pressed is activated to transmit a request signal to the keyless start remote controller (4). When the keyless start remote control receives the request signal, it transmits the security code to the keyless start controller (built-in antenna) (11). If the keyless start controller (1) verifies this code against the registered security code, it uses CAN communication to output the lock/unlock request signal to the BCM (2) in accordance with the condition of the door lock switch at that time. This activates the door lock mechanism (3).

Figure 9: Door lock function (AZH412/414)


3.3.1 Keyless controller operating range For the door lock function to be certain to operate, the keyless start remote control must be within about 80 cm of a door antenna. [1] Right door antenna [2] Left door antenna [3] Rear end door antenna

Reference: The operation range may vary slightly according to

conditions in the area and transmitter battery condition. If 2 vehicles that are equipped with a keyless start system

are parked next to each other and their keyless start systems are operated at the same time, the door lock function may not operate.

If a keyless start remote control that has been registered and one that has not been registered are carried at the same time, the door lock function may not operate.

When the keyless start remote control is within the operation range of the driver's door antenna, the doors can only be locked or unlocked with the driver's door request switch.

3.3.2 Safety function The doors cannot be locked or unlocked with a door request switch under the following conditions. When the key switch is ON (when the key is inserted into

the ignition switch) When a door is open When the keyless start remote control is inside the vehicle

3.3.3 Vehicle lock-in prevention function for keyless start remote control This function prevents the driver from locking the doors and leaving the vehicle while the keyless start remote control is still inside. When the keyless start controller detects the locking of the driver's door or front passenger's door while the driver's door or front passenger's door is open, it activates the interior antenna and luggage antenna. If the controller judges that the keyless start remote control is within the detection area of one of these antennas, it outputs an unlock request signal to the BCM.

The vehicle lock-in prevention function may not operate correctly if the keyless start remote control is in certain areas of the luggage compartment, on top of the instrument panel, or inside the glove box or a door pocket. 3.3.4 Timer lock function If a door is not opened within 30 seconds of unlocking the doors with a door request switch, they are automatically relocked. The timer lock function is canceled if a door is opened within 30 seconds of unlocking, the key switch or the push switch of the engine start knob is turned ON, or the driver's door lock switch is locked. 3.3.5 Registration function In the keyless start system, up to 4 keyless start remote controls can be registered in one keyless start controller. Be careful of the following conditions. When registering a keyless start remote control, the

security codes are erased for all the remote controls that were previously registered. This means that registration must be performed for all the keyless start remote controls, and not just the additional one.

When registering a keyless start remote control, do not put remote controls other than the ones you want to register inside the vehicle.

A mechanical key for which immobilizer registration has been performed is required when registering a keyless start remote control.

3.4 Engine start function 3.4.1. Starting procedure (models with engine start knob) When the engine start knob (push switch) on the steering lock unit is pressed (1), the keyless start controller activates the interior antenna to transmit a request signal to the keyless start remote control (2). When the keyless start remote control receives the request signal, it transmits the security code to the keyless start controller (built-in antenna) (3). If the keyless start controller verifies this code against the registered security code, it uses CAN communication to output the keyless start indicator (blue light) signal to the combination meter (4). It also uses serial communication to output a steering lock release signal to the steering lock unit (5) to release the steering lock. This enables the rotation of the engine start knob. Also, when the engine start knob is turned to the ON position, the keyless start controller uses CAN communication to output an engine start permission signal to the ECM (6) that allows the engine to be started.

3.4.1.1. When starting is not possible If the keyless start remote control is not inside the vehicle or the keyless start remote control has not been registered, the keyless start controller uses CAN communication to output the keyless start indicator (red light) signal to the combination meter. This alerts the driver and prevents a steering lock release signal from being output to the steering lock unit. When the steering lock is not released, the engine start knob cannot be rotated and the engine cannot be started.

Figure 12: Engine starting function

3.4.1.2 Alert and warning functions


Reference: If the keyless start remote control is taken

outside the vehicle while the engine is running, and the driver stops the engine (engine start knob to ACC position) and then tries to restart it, although the starter motor operates, the immobilizer system prevents the engine from starting.

Keyless start remote control verification is not performed while the key is inserted in the key cylinder (key switch: ON). In addition, even when a registered keyless start remote control is being carried, the engine cannot be started with an unregistered mechanical key.

If a keyless start remote control that has been registered and one that has not been registered are carried at the same time, it may not be possible to start the engine.

When the immobilizer warning lamp flashes at the same time as the alert or warning function of the keyless start system operates, the engine cannot be started because the immobilizer system is operating.

3.4.2 Starting procedure (models with push start button) The method of starting engine is as follows. 1) When brake pedal is depressed with shift position in P or

N (CVT model) or when clutch pedal is depressed (M/T model), keyless start control module (1) sends request signal to combination meter (2) through CAN communication to display PUSH START SWITCH on the information display.

2) Push engine switch (3) with remote controller (4) being carried.

3) Keyless start control module activates mid inside antenna (5) to send request signal to remote controller.

4) Remote controller receives request signal and then sends ID code to keyless start control module via keyless entry receiver (6). 5) Keyless start control module compares ID code sent from remote controller with ID code registered in keyless start control module. If ID codes match, keyless start control module outputs a steering lock release request signal to steering lock unit (7). At the same time, it outputs engine start signal to ECM (8) and turns the starting motor control relay ON to activate the starting motor (9). This enables the steering lock to be released and the engine to be started. 3.4.2.1 Changing Ignition Mode When engine switch is pushed with remote controller inside

cabin and brake pedal (CVT model) or clutch pedal (M/T model) released, keyless start control module compares the ID code sent by remote controller with the ID code registered in keyless start control module. When these ID codes match, keyless start control module controls ON/OFF of the ACC, IG1, and IG2 relays according to engine switch operation for switching ignition mode from OFF ACC ON (engine not running) OFF. When mode is in ACC, IGNITION SWITCH POSITION ACC is shown on the display. When mode is in ON (engine not running), IGNITION SWITCH POSITION ON is shown on the display.

For CVT model, keyless start control module judges whether select lever is in P range or not by the state of P range switch. This prohibits ignition mode switching from ACC to OFF with select lever in any position other than P range.

Table below shows transition of ignition mode according to engine switch operation. One arrow indicates transition by pressing engine switch once.

3.5 Diagnostic function for keyless start system 3.5.1 Self diagnosis function Description The keyless start control module monitors conditions of the system components and its circuit. When an abnormality in the system occurs, the keyless start control module controls as follows: a) Self-Diagnosis Function Keyless start control module is equipped with self-diagnosis function that stores DTC for abnormalities detected in keyless start system, immobilizer control system and power window system. Stored DTC is saved until abnormality is corrected. b) Warning Function When a malfunction of keyless start system and immobilizer control system is detected, keyless start control module makes theft deterrent light or immobilizer indicator light turn on. Depending on the malfunction, a message is shown in information display to warn the driver (Kizashi) Warning function is not shown when a malfunction of the

power window system is detected. After detecting a malfunction, theft deterrent light and

immobilizer indicator light are turned on. However they are turned off when normal condition is judged.

c) Fail-Safe Control Keyless start control module operates fail-safe control when an abnormality related to keyless start system is detected and stops all control in order to protect system. Details of fail-safe control vary depending on the detected DTC.

Reference: When DTC B1194 is detected, immobilizer indicator

light stays on until normal condition is judged at least twice in a row.

When a malfunction of power window system and immobilizer control system is detected, keyless start control module does not perform fail-safe control. However, in power window system, each power window switch separately performs fail-safe control to stop AUTO mode

3.5.5 Remote controller registration The following remote controller registration procedure applies to the following Suzuki models: Kizashi (A6B424) Swift (AZH models) Registration procedure Register remote controller ID code using Immobilizer Key

Registration function in SDT. Remote controller registration is performed through

Immobilizer Key Registration, and this registers the immobilizer transponder code.

Performing Immobilizer Key Registration clears all of the ID codes already registered. Prepare all of the remote controllers.

It is possible to register 4 remote controllers in keyless start control module.

If the keyless start control module is replaced, replace all of the remote controllers (Swift AZH models only)

If the keyless start control module is replaced, register all of the remote controllers (Kizashi A6B424 only)

If all of the remote controllers are lost, register remote controllers after replacing keyless start control module.

The following remote controller registration procedure applies to the following Suzuki models equipped with keyless start systems: Swift (RS models) Grand Vitara SX4 If remote controller or keyless start control module is replaced or additional remote controller is necessary, register ID code(s) of remote controller. 1) Sit in driver seat and close all doors. 2) Check that door lock of driver seat is unlocked. 3) Insert ignition key (1) into ignition key cylinder. 4) Perform Steps a) through f) described blow within 25 seconds after Step 3). a)First push manual door lock switch (2) toward lock side (3) and then push it toward unlock side (4). b) Repeat Step a) 2 more times. c) Push lock side of manual door lock switch. d) Remove ignition key from ignition key cylinder once and then insert it again. e) Repeat Step d) 3 more times. f) Start engine and wait for 3 seconds. 5) Turn ignition switch to OFF position. When ignition switch is turned to OFF position, buzzer sounds twice and door lock is activated from lock position to unlock position. This operation indicates that keyless start control module has entered registration mode.

6) Push lock or unlock button of remote controller (within 30 seconds after Step 5) to be registered. When lock or unlock button of remote controller is pushed, buzzer sounds twice, door lock is activated to lock position and then to unlock position. This operation indicates that remote controller ID code has been registered in keyless start control module. If an additional remote controller needs to be registered, repeat the procedure of Step 6) within 30 seconds after Step 5). 7) To end registration mode, remove ignition key from ignition key cylinder or turn it to ON position. In case of vehicle equipped with immobilizer control system, if engine start function of keyless start system does not work after registration, check ECM if DTC P1615 is detected. If it is detected, go to DTC P1615: Steering Lock Unit Communication Error. If it is not detected, perform registration procedure again.

Figure 17: Remote controller registration


It is possible to register up to 4 remote controllers in keyless start control module.

Setting keyless start control module to ID code registration mode of remote controller will erase all remote controller ID codes that have been registered in keyless start control module. Therefore, when registering remote controller ID codes in keyless start control module, have all of those to be registered ready and execute their registration at the same time.

When registration of more than four remote controller ID codes is attempted, the oldest remote controller ID code will be erased and that inputted after the fourth one will be registered.

When keyless start control module which was used in another vehicle has been installed, register the ID code of the remote controller to the keyless start control module first and then the following code.

With immobilizer control system, register the ignition key transponder code for the immobilizer control system in ECM

Without immobilizer control system, register the steering lock unit ID code in keyless start control module. For registration procedure of that, refer to Keyless Start Registration.
