Normal Operation and Fault Conditions
The RCM continuously monitors the right front impact sensor circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
- Faulted right front impact sensor
If a fault is detected, the RCM stores DTC B1417:11, B1417:12, B1417:13 or B1417:96 in memory and sends a message to the IPC to illuminate the airbag warning indicator.
PPT AB RCM DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B1417:11 | Passenger Frontal Restraints Sensor: Circuit Short to Ground | Sets when the RCM senses a short to ground from the right front impact sensor feed circuit, or a short to voltage from the sensor feed circuit that is less than the normal sensor operating voltage. |
| B1417:12 | Passenger Frontal Restraints Sensor: Circuit Short to Battery | Sets when the RCM senses a short to voltage from the right front impact sensor feed circuit that is greater than the normal sensor operating voltage. |
| B1417:13 | Passenger Frontal Restraints Sensor: Circuit Open | Sets when the RCM senses an open right front impact sensor feed circuit, or a short to voltage from the sensor feed circuit that is within a predetermined range from the normal sensor operating voltage. |
| B1417:96 | Passenger Frontal Restraints Sensor: Component Internal Failure | Sets when the RCM senses a short to ground from the right front impact sensor feed circuit, or a short to voltage from the sensor feed circuit that is less than the normal sensor operating voltage. |
