Kia Soul EV: SRSCM / SRS Control Module (SRSCM) Repair procedures

Kia Soul EV (PS EV) 2015-2020 Service Manual / Restraint / SRSCM / SRS Control Module (SRSCM) 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 to work.

3.	Disconnect the DAB, PAB, SAB, CAB and BPT connectors.

4.	Remove the floor console. (Refer to Body - "Floor console")

5.	Remove the rear heating joint duct (A).

6.	Pull up the lock of the SRSCM connector and disconnect the connector (A).

7.	Remove the SRSCM mounting bolts (3EA) from the SRSCM, and 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 to work.

Install the SRSCM with the SRSCM mounting bolts.

Tightening torque (SRSCM Mounting Bolt) :

7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.7 ~ 7.3 lb-ft)

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

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

4.	Connect the SRSCM harness connector.

5.	Install the rear heating joint duct.

6.	Install the floor console. (Refer to Body - "Floor console")

7.	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.

Variant coding

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

1)	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) when attempting the Variant Coding, DTC B1762 will be displayed instead. In this case, charge the battery as the first thing and then proceed with the variant coding procedure.

This is because although Variant Coding is normally performed, DTC B1762 and low battery will be displayed.

Variant coding Procedure

?nbsp; On-Line type on GDS

1.	Ignition "OFF", connect scan tool.

2.	Ignition "ON" & Engine "OFF" select vehicle name and airbag system.

3.	Select Variant coding mode.

4.	Follow steps as in screen shots below.

1) Initial ACU Variant Coding screen

2) VIN Code entering screen

3) Variant coding''s proceeding screen-1

4) Variant coding''s proceeding screen-2

5) Variant coding is completed

1)Text display for Incomplete ACU Coding after finiching variant coding

2) Screen of communication failure

?nbsp; Off-line type on GDS (This can be used when not connected to the internet)

1) Initial ACU Variant Coding screen

2) ACU CODING Code entering screen

3) echecking previously entered ACU CODING code

4) Variant coding''s proceeding screen-1

5) Variant coding''s proceeding screen-2

6) Variant coding is completed

1) Screen of incomplete ACU coding after finishing variant coding
