Fault-Tracing Information

Fault-tracing

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.
- Download new software to the Forward Sensing Module (FSM) under the SOFTWARE tab.
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.






Note! More information is available in Design and function.

Remedy as necessary.
