Checking Configuration Id

The main supplemental restraint system module (SRS) on sensor-CAN sends out a configuration ID that is checked by other nodes. When the control modules' configuration IDs do not correspond, a DTC is stored. The fault can be due to a customer or workshop replacing a control module without downloading new software for the replacement. Attempt to remedy the fault by downloading new software to the control module.

If the fault persists after reprogramming the Forward Sensing Module (FSM):Fault trace the cables for sensor CAN between the Forward Sensing Module (FSM) and the Supplemental restraint system module (SRS).

Fault-tracing information 

The list below shows which DTCs can be stored on the local network sensor CAN (reservation for future changes/updates). The table indicates where on the local network sensor CAN there may be a fault.

DTC-TABLE: FOR THE LOCAL NETWORK SENSOR CAN
