Checking the component

Caution! Do not touch the terminal pins in the supplemental restraint system module (SRS) and the central electronic module (CEM). There is a risk of static discharge. This could damage the supplemental restraint system module (SRS) and the central electronic module (CEM).








- Switch off the ignition. Wait 10 seconds
- Disconnect the connector from the supplemental restraint system module (SRS)
- Disconnect connector D from the central electronic module (CEM).
Check the connectors for the supplemental restraint system module (SRS) and the central electronic module (CEM). Check for damage to pins and terminals in the connectors. Also check the wiring.
Remedy as necessary.
Check what type of crash safety equipment the central electronic module (CEM) and the supplemental restraint system module (SRS) are programmed for.
- Connect the connector for the supplemental restraint system module (SRS)
- Connect the connector for the central electronic module (CEM)
- Switch on the ignition. Wait 10 seconds
- Read off by clicking the VCT2000 symbol.
As part of the check, a comparison is performed regarding whether the control modules are programmed for the following:
- Occupant weight sensor (OWS).
If the control modules are programmed for different types of crash safety equipment:
Check whether the crash safety equipment that does not correspond in the comparison between the control modules is installed in the vehicle.
Remedy faulty equipment and/or download new software into the incorrectly programmed control module.
