Test X: DTC B229B - Occupant Classification System Obstruction

PINPOINT TEST X: DTC B229B - OCCUPANT CLASSIFICATION SYSTEM OBSTRUCTION

Normal Operation
The occupant classification sensor (OCS) 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 obstruction of both OCS rails, it will store DTC B229B 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 B229B Occupant Classification System Obstruction - If the OCSM detects a negative force on one or both OCS rails (weight sensors), it will set this DTC.

This pinpoint test is intended to diagnose the following:
- A foreign object placed under or contacting the passenger seat
- OCS system component(s)
