Air Bag Control Module: Testing and Inspection

Configuration Of SRS Control Module







As delivered from the manufacturer, the SRS control module is not functional until it has been programmed for the car in which it has been fitted. In the programming procedure the functions of the control module are compared with the hardware that is in place in the car.

The control module checks whether the requested programming is compatible with the components that it detects electrically in the car, until the ignition is switched off. If the detected components are not compatible with the desired programming, a diagnostic trouble code will be generated. In this way it is possible to find out why the car's equipment and the desired control module programming are incompatible.

When changing the control module, the replacement must be programmed for the car in which it is to be fitted. This is done with the diagnostic tool.

After programming has been successfully completed, the parameters will be locked in the control module and cannot be changed.

Programming
1. Connect the diagnostic tool to the diagnostic socket under the dashboard.
2. Select the current car and model year on the diagnostic tool.
3. Work your way to the SRS directory and select programming.
4. Read the control module configuration with respect to the passenger airbag.
5. Adjust settings as necessary.
6. Switch the ignition on and read off the diagnostic trouble codes.
