Third generation YP (2014-2023) / Kia Sedona YP Service Manual / Restraint / SRSCM / SRS Control Module (SRSCM) Repair procedures

Remove the ignition key from the vehicle.
Disconnect the battery negative cable and wait for at least thirty seconds before beginning work.
Remove the floor console.
(Refer to Body - "Floor console")
Pull up the lock of the SRSCM connector, and then disconnect the connector (A).

Remove the SRSCM mounting bolts (3EA) from the SRSCM, and then remove the SRSCM.
You must remove or install SRSCM or other SRS components with the ignition switch OFF to avoid accidental airbag deployment.
Remove the ignition key from the vehicle.
Disconnect the battery negative cable and wait for at least 30 seconds before beginning to work.
Install the SRSCM with the SRSCM mounting bolts.

Tightening torque :
7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)

Use new mounting bolts when replacing the SRSCM after a collision.
Connect the SRSCM harness connector.
Install floor console.
(Refer to Body - "Floor console")
Reconnect the battery negative cable.
After installing the SRSCM, confirm proper system operation:
Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.
SRSCM senses vehicle rollovers. SAB, CAB, BPT may deploy if a technician moves the SRSCM from the vehicle in IGN ON state. For this reason, turn the IGN OFF before safely removing the SRSCM from the vehicle.
When the SRSCM is replaced, always perform variant coding. Also, perform the lateral G sensor 0-point setup.
(Refer to Brake System – “Yaw-rate and Lateral G Sensor”)
Variant coding
After replacing the SRSCM with a new one, the "Variant Coding" procedure MUST be performed.
In SRSCM variant coding mode, the airbag warning lamp periodically flickers (ON: 0.5sec., OFF: 0.5sec.) until the coding is normally completed.
If the variant coding has 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.
If the battery voltage is low (less than 9V), DTC B1102 will be displayed. In this case, charge the battery before anything else, and then perform the variant coding procedure.
DTC B1762 (ACU Coding Error) and B1102 (Battery Voltage Low) may be displayed simultaneously.
