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

4.	Remove the floor air duct (A).

5.	Disconnect the SRSCM connectors.

6.	Remove the SRSCM (A) after loosening the mounting nuts.

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 (A) with the SRSCM mounting nuts.

Tightening torque :

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

4.	Connect the SRSCM harness connectors.

5.	Install the heater ducts and floor console. (Refer to Body - "Floor Console Assembly")

6.	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.

•	If 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.

1)	On SRSCM variant coding mode, the airbag warning lamp periodically blinks (ON: 0.5sec., OFF: 0.5sec.) until the coding is normally completed.

If the variant coding fails, DTC B176200 (ACU Coding Error) will be displayed and the warning lamp will turn 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 B168300 (Exceed Maximum coding Number) will be displayed and SRSCM must be replaced.

3)	If the battery voltage is low (less than 9V), DTC B110200 will be displayed. In this case, charge the battery before anything else, and then perform the variant coding procedure. DTC B176200 (ACU Coding Error) and B110200 (Battery Voltage Low) may be displayed simultaneously.
