Repair Procedures

Removal

1. Remove the ignition key from the vehicle.
2. Disconnect the battery negative cable and wait for at least three minutes before beginning work.
3. Disconnect the DAB, PAB, SAB, CAB and BPT connectors.
4. Remove the floor console.
5. Pull the lock (1) forward. Pull the lever (3) after pressing the lever lock (2). Disconnect the airbag system control module (SRSCM) connector (A) and (B).




6. Disconnect the SRSCM harness connector(A) and (B) from the SRSCM.
7. Remove the SRSCM mounting bolts(3EA) from the SRSCM, then remove the SRSCM.






Installation

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

Tightening torque (SRSCM Mounting Bolt)
: 7.8 - 9.8 Nm (0.8 - 1.0 kgf.m, 5.7 - 7.3 lb.ft)

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

4. Connect the SRSCM connector (A) and (B) by pushing the lever (3) and lock (1) completely.





NOTE:
When installing the airbag wiring harness, ground points(C) must be installed.

5. Install the floor console.
6. Connect the DAB, PAB, SAB, CAB and BPT connectors.
7. Reconnect the battery negative cable.
8. After installing the SRSCM, confirm proper system operation:
A. Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.

Variant coding

After replacing the SRSCM with a new one, MUST perform the "Variant Coding" procedure.

NOTE:
1. On SRSCM variant coding mode, the airbag warning lamp is periodically blinking (ON: 0.5sec., OFF: 0.5sec.) until the coding is normally completed.
2. If the variant coding is failed, DTC B1762 (ACU Coding Error) will be displayed and the warning lamp will be turned on.
In this case, perform the variant coding procedure again after confirming the cause in "DTC Fault State Information".
Variant Coding can be performed up to 255 times, but if the number of coding work exceeds 255 times, DTC B1683 (Exceed Maximum coding Number) will be displayed and SRSCM must be replaced.
3. If the battery voltage is low (less than 9V) before performing the Variant Coding, DTC B1762 will be displayed only. In this case, charge the battery before anything else, and then perform the variant coding procedure.
Because, although Variant Coding is normally performed, DTC B1762 and low battery are displayed.
