Diagnostic Overview
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 airbag warning indicator.
| 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. |
