Normal Operation
The Restraints Control Module (RCM) checks the Occupant Classification Sensor (OCS) circuits for faults. If the RCM detects one of the following faults on any of the OCS circuits, it will store Diagnostic Trouble Code (DTC) B2290 in memory and flash either Lamp Fault Code (LFC) 16 (or higher priority code if one exists) on the air bag indicator.

Fault Conditions
The RCM monitors for the following fault conditions:
^ Low resistance.
^ Circuit open.
^ Circuit short to battery.
^ Circuit short to ground.

Possible Causes
A occupant classification sensor (OCS) circuit fault can be caused by:
^ Wiring, terminals, or connectors.
^ A faulty OCS module.
^ A faulty OCS MAT sensor.
^ A faulty OCS pressure transducer.
^ RCM.
