Kia Sportage: SRS Control Module (SRSCM): Repair procedures

Third generation SL (2010–2016) / Kia Sportage SL Service & Repair 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 work.

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

4.	Remove the floor console upper cover. (Refer to the Body group - console)

5.	Remove the shift lever assembly. (Refer to the transaxle system group - shift lever)

6.	Pull the lock (1) forward and then pull the lever (3) after pressing the lever lock (2). Disconnect the airbag system control module connector. (A and B)

Remove the SRSCM mounting nuts(3EA) from the SRSCM, then remove the SRSCM.

You must remove or install SRSCM at the ignition switch OFF because SRSCM has overturn sensing function. SAB, CAB, BPT may be deployed if you shake SRSCM at the direction of up and down or right and left at the ignition switch ON.

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.

Install the SRSCM with the SRSCM mounting nuts.

Tightening torque :

6.8 ~ 9.2 N.m (0.7 ~ 0.9 kgf.m, 5.0 ~ 6.8 lb-ft)

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

4.	Connect the SRSCM harness connector.

5.	Install the shift lever assembly. (Refer to the transaxle system group - shift lever)

6.	Install the floor console upper cover. (Refer to the Body group - console)

7.	Connect the DAB, PAB, SAB, CAB and BPT connectors.

8.	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 can sense a vehicle rollover. SAB, CAB, BPT can deploy if mechanic moves the SRSCM on vehicle during IGN ON state. For this reason, be sure to turn the IGN OFF and then remove the SRSCM from vehicle.

Variant coding

After replacing the SRSCM with a new one, the “Variant Coding” procedure must be preformed.

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.

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), 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.

Variant coding Procedure

?nbsp; On-Line type on GDS

1.	Ignition "OFF", connect GDS.

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

3.	Select Variant coding mode.

4.	Follow steps on the screen as 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) This screen is opened when you try the variant coding again on the SRSCM which has bee performed variant coding.

2) Screen of communication failure

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

1) Initial ACU Variant Coding screen

2) ACU Coding Code entering screen

3) Screen of rechecking ACU Coding code''s entering

4) Variant coding''s proceeding screen-1

5) Variant coding''s proceeding screen-2

6) Variant coding is completed

1) This screen is opened when you try the variant coding again on the SRSCM which has bee performed variant coding.
