Kia Soul EV (PS EV) 2015-2020 Service Manual / Brake System / ESP(Electronic Stability Program) System / Yaw-rate and Lateral G Sensor 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, 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 the vehicle rollover. SAB, CAB and BPT may be deployed if SRSCM was shaken up and down or left and right during IGN ON state. For this reason, make sure that the IGN is turned OFF before removing the SRSCM from the vehicle.

•	If the SRSCM is replaced always perform variant coding. Also, perform the lateral G sensor calibration. (Refer to Restraint - "SRS Control Module")

G-Sensor Calibration

1.	Turn ignition "OFF" and connect GDS.

2.	While ignition "ON" & engine "OFF", select vehicle name and ESC system.

3.	Perform G-sensor calibration.

4.	Perform the "G-Sensor Calibration" procedure with GDS.

5.	Complete the "G-Sensor Calibration" procedure.
