Test W: DTC B229A - Occupant Classification System Contamination

PINPOINT TEST W: DTC B229A - OCCUPANT CLASSIFICATION SYSTEM CONTAMINATION

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 occupant classification system module (OCSM) monitors the 2 OCS rails (weight sensors) and circuity for faults. If the OCSM detects an object within the OCS rails, it will store DTC B229A in memory and send a message to the restraints control module (RCM) which sends a message to the instrument cluster (IC) module to illuminate the air bag warning indicator.

- DTC B229A Occupant Classification System Contamination - If the OCSM detects foreign object(s)/substance in one or both OCS rails (weight sensors), it will set this DTC.

This pinpoint test is intended to diagnose the following:
- A foreign object within an OCS rail
- OCS system component
