Test R: DTC B229B - Occupant Classification System Obstruction

PINPOINT TEST R: DTC B229B - OCCUPANT CLASSIFICATION SYSTEM OBSTRUCTION

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 weight sensors and circuitry for faults. If the OCSM detects an obstruction on one or all OCS weight sensors, 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 illuminates the air bag indicator.

- DTC B229B Occupant Classification System Obstruction - If the OCSM detects a negative force on one or all OCS 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)
