B00C2:11 and B00C2:12
Refer to OEM Wiring Diagrams - SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.
The BTS operates in conjunction with the OCS. The OCSM provides a reference voltage to the BTS, which changes as it passes through the sensor, based on how much tension is applied to the safety belt and BTS.
The OCSM monitors the BTS reference voltage circuit for the following faults:
- Short to voltage
- Short to ground
If a fault is detected, the OCSM stores DTC B00C2:11 or B00C2:12 in memory and sends a message to the RCM over the HS-CAN indicating that an OCS fault is present. Upon receipt of this message, the RCM sets DTC B00A0:09 and sends a message over the HS-CAN to the IPC to illuminate the air bag warning indicator.
DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B00C2:11 | Passenger Seat Occupant Classification Sensor "C": Circuit Short to Ground | A fault is indicated when the OCSM senses a short to ground on the BTS reference voltage circuit. |
| B00C2:12 | Passenger Seat Occupant Classification Sensor "C": Circuit Short to Battery | A fault is indicated when the OCSM senses a short to voltage on the BTS reference voltage circuit. |
