The occupant classification sensor (OCS) system is used to classify the front passenger seat occupant in the event of a deployable impact. Refer to AIR BAG AND SAFETY BELT PRETENSIONER SUPPLEMENTAL RESTRAINT SYSTEM (SRS) .
The OCS system monitors the 2 OCS rails (weight sensors) and circuity for faults. If the OCS module detects an object within the OCS rails, it will store diagnostic trouble code (DTC) B229A in memory and send a message to the restraints control module (RCM) which illuminates the air bag indicator.
