Kia Stinger: SRSCM / SRS Control Module (SRSCM)

Kia Stinger CK 2018-2020 Service Manual / Restraint / SRSCM / SRS Control Module (SRSCM)

Description and operation
Description

The primary purpose of the SRSCM (Supplemental Restraints System Control Module) is to discriminate between an event that warrants restraint system deployment and an event that does not. The SRSCM must decide whether to deploy the restraint system or not. After determining that pretensioners and/or airbag deployment is required, the SRSCM must supply sufficient power to the pretensioners and airbag igniters to initiate deployment.

The SRSCM determines that an impact may require deployment of the pretensioners and airbags from data obtained from impact sensors and other components in conjunction with a safing function.

The SRSCM will not be ready to detect a crash or to activate the restraint system devices until the signals in the SRSCM circuitry stabilize.

It is possible that the SRSCM could activate the safety restraint devices in approximately 2 seconds but is guaranteed to fully function after prove-out is completed.

The SRSCM must perform a diagnostic routine and light a system readiness indicator at key-on. The system must perform a continuous diagnostic routine and provide fault annunciation through a warning lamp indicator in the event of fault detection. A serial diagnostic communication interface will be used to facilitate servicing of the restraint control system.

Components

1. Supplemental Restraint System Control Module (SRSCM)


Repair procedures
Removal
1.

Disconnect the negative battery terminal and wait for at least thirty seconds before beginning to work.

2.

Remove the floor console assembly.

(Refer to Body - "Floor Console Assembly")

3.

Disconnect the Supplemental Restraint System Control Module (SRSCM) connector (A).

4.

Loosen the bolt and nuts and then remove the Supplemental Restraint System Control Module (SRSCM).

  

Switch "OFF" the ignition when removing or installing SRSCM or other SRS components to avoid accidental airbag deployment.

Installation
1.

Remove the ignition key from the vehicle.

2.

Disconnect the negative battery terminal and wait for at least thirty seconds before beginning to work.

3.

Install the SRSCM with the SRSCM mounting bolt and nuts.

Tightening torque :

9.4 - 13.5 N·m (0.96 - 1.38 kgf·m, 6.9 - 9.9 lb·ft)

4.

Connect the SRSCM harness connector.

5.

Install the floor console assembly.

(Refer to Body - "Floor Console Assembly")

6.

Reconnect the negative battery cable.

7.

After installing the SRSCM, confirm proper system operation:

Switch ON the ignition. The SRS indicator light should turn on for about six seconds and then off.

Variant coding

After replacing the SRSCM, the “Variant Coding” must be performed.

  
1)

During the SRSCM variant coding mode, the airbag warning lamp periodically blinks (ON: 0.5 s, OFF: 0.5 s) until the coding is completed properly.

2)

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

■ On-Line method on KDS
1.

Switch "OFF" ignition, and connect KDS.

2.

With 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

2) Enter VIN Code

3) Processing variant coding - 1

4) Processing variant coding - 2

5) Variant coding is completed

  

1) This screen is displayed when the variant coding is attempted again on the SRSCM that has already performed variant coding.

2) Communication failure

■ Offline method on KDS (When internet connection is unavailable)

1) Initial ACU Variant Coding

2) Enter ACU Coding Code

3) Recheck ACU Coding code

4) Processing variant coding - 1

5) Processing variant coding - 2

6) Variant coding is completed

  

This screen is displayed when the variant coding is attempted again on the SRSCM that has already performed variant coding.
