The OCSM monitors OCS weight sensor bolt "C" and circuitry for faults. If the OCSM detects a fault, it stores DTC B00C2:12, B00C2:13 or B00C2:1A in memory and sends a message to the RCM , which stores DTC B00A0:09 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

DTC DESCRIPTION
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| B00C2:12 | Passenger Seat Occupant Classification Sensor "C": Circuit Short To Battery | A fault is indicated when the OCSM measures voltage on the OCS weight sensor bolt "C" signal circuit above 4.85 volts. An open sensor return circuit also sets this DTC. |
| B00C2:13 | Passenger Seat Occupant Classification Sensor "C": Circuit Open | A fault is indicated when the OCSM measures resistance above a calibrated threshold on the OCS weight sensor bolt "C" signal circuit. |
| B00C2:1A | Passenger Seat Occupant Classification Sensor "C": Circuit Resistance Below Threshold | A fault is indicated when the OCSM measures resistance below a calibrated threshold on the OCS weight sensor bolt "C" signal circuit. |
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- OCS weight sensor bolt "C"
- OCSM
