Normal Operation and Fault Conditions
The RCM monitors the passenger door and the second row left side impact sensors and circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted passenger door side impact sensor
- Faulted second row left side impact sensor
The RCM communicates with each impact sensor. If the RCM is unable to communicate with the sensor, a DTC is stored in memory. A CMDTC no operation (failure type: 93) can be set by a short to voltage on the return circuit of the impact sensor.
PPT Z RCM DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1415:81 | Driver Side Restraints Sensor 2: Invalid Serial Data Received | Sets when the RCM senses a faulted left C-pillar side impact sensor or an open from the left C-pillar side impact sensor circuits. |
| B1418:11 | Passenger Side Restraints Sensor 1: Circuit Short to Ground | Sets when the RCM senses a shorted passenger door side impact sensor, a shorted left C-pillar side impact sensor, a short to ground from the passenger door side impact sensor feed circuit or a short to ground from the left C-Pillar side impact sensor feed circuit. |
| B1418:81 | Passenger Side Restraints Sensor 1: Invalid Serial Data Received | Sets when the RCM senses a faulted passenger door side impact sensor or an open from the passenger door side impact sensor circuits. |
| B1418:93 | Passenger Side Restraints Sensor 1: No Operation | Sets when the RCM senses a faulted left C-pillar side impact sensor or passenger door side impact sensor, or a short to voltage from the feed or return circuit of the left C-pillar side impact sensor or passenger door side impact sensor. |
