SRS Control Module (SRSCM) Repair Procedures

Removal

1. 1
   Remove the ignition key from the vehicle.
2. 2
   Disconnect the negative battery cable and wait at least three minutes before starting work.
3. 3
   Remove the floor console. (Refer to Body - Console)
4. 4
   Remove the bolt (A), then remove the rear ventilation duct (B).

   

5. 5
   Pull the lock (1) forward and pull the lever (3) after pressing the lever lock (2). Disconnect the SRSCM connectors (A) and (B).

   

6. 6
   Remove the SRSCM mounting bolts (3 pcs) from the SRSCM, then remove the SRSCM.

Installation

1. 1
   Remove the ignition key from the vehicle.
2. 2
   Disconnect the negative battery cable and wait at least three minutes before starting work.
3. 3
   Install the SRSCM using the SRSCM mounting bolts.

   Tightening torque: 8.0 ~ 10 N·m

   

   Use new mounting bolts when replacing the SRSCM after a collision.

4. 4
   Connect the SRSCM wiring harness connector.
5. 5
   Install the rear ventilation duct and floor console. (Refer to Body group - Console)
6. 6
   Connect the negative battery cable.
7. 7
   After installing the SRSCM, check that the system operates correctly:

   • Turn the ignition ON; the SRS indicator should illuminate for approximately six seconds, then turn off.

Variant Coding

1 In variant coding mode of the SRSCM, the airbag warning lamp illuminates and flashes periodically (ON: 0.5 s, OFF: 0.5 s) until the coding is completed normally. 2 If variant coding fails, DTC B1762 (ACU coding error) will be displayed and the warning lamp will illuminate. In this case, repeat the variant coding procedure after confirming the cause in "DTC Fault State Information". Variant coding can be performed up to 255 times. If the number of coding operations exceeds 255, DTC B1683 (maximum coding number exceeded) will be displayed and the SRSCM must be replaced. 3 If the battery voltage is low (less than 9 V), DTC B1102 will be displayed. In this case, first charge the battery, and then perform the variant coding procedure. DTC B1762 (ACU Coding Error) and B1102 (Low Battery Voltage) may be displayed at the same time.
