B229A MAZDA Description

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 Sensor 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 illuminates the air bag indicator.
