Normal Operation
The Occupant Classification System Module (OCSM) monitors each Occupant Classification Sensor (OCS) weight sensor bolt for correct calibration/weight and identification. When the ignition is ON and the OCSM detects a fault from any of the 4 sensors or if an OCS system component has been installed new, it will store DTC B1013 in memory and send a message to the Restraints Control Module (RCM)
The RCM will store DTC B2290 in memory and send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- OCS system component
- Passenger seat track
OCS weight sensor bolt location
- Weight sensor bolt A (1) front outboard
- Weight sensor bolt B (2) rear outboard
- Weight sensor bolt C (3) rear inboard
- Weight sensor bolt D (4) front inboard
