Checking Communication
The control modules on the local network sensor CAN can detect short-circuit faults when they send signals. Fault trace the wiring for short-circuits.
Check the CAN communication between the Supplemental Restraint System Module (SRS), Closing velocity module (CVM) and Occupant Weight Sensor (OWS) (only USA/CAN markets).
If no malfunction is found:Fault trace the Closing velocity module (CVM).
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
| DTC in control module | Short-circuit, open-circuit, internal fault, damaged control module ("bus-off") | Incorrect configuration ID | SRS, signal missing | BCM, signal missing | FSM, signal missing | CVM, signal missing | OWS, signal missing |
| SRS | U002800 | - | - | - | - | U023500 | U015400 |
| Brake control module | U002888 | U002855 | U015100 | - | U010400 | U023500 | - |
| FSM | U002888 | U002855 | U015100 | - | - | - | - |
