Normal Operation
The occupant classification sensor (OCS) system is used to classify the front passenger seat occupant in the event of a deployable impact.

The OCS module monitors internal circuity, hardware and the 4 OCS weight sensor bolts and circuitry for faults. If the OCS module detects a fault with the internal circuitry, internal hardware, sensor(s) or circuitry, it will store diagnostic trouble code (DTC) B1342 in memory and send a message to the restraints control module (RCM). The RCM will store DTC B2290 in memory and send a message to the instrument cluster module to illuminate the air bag warning indicator.

Fault Conditions
The OCS module monitors for the following fault conditions:
- A faulted circuit(s)
- An OCS weight sensor bolt fault
- An OCS module internal fault

Possible Causes
An OCS system fault can be caused by:
- damaged wiring, terminals or connectors.
- a faulted OCS system component.
