Test I: DTC B2290 - Occupant Classification Sensor (OCS) System Fault

PINPOINT TEST I: DTC B2290 - OCCUPANT CLASSIFICATION SENSOR (OCS) SYSTEM FAULT

Lamp Fault Codes (LFC)
The following LFCs indicate the specific fault PIDs associated with DTC B2290:












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 OCS system components (seat cushion foam pad, bladder with pressure sensor and electronic control unit) are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately. If a new OCS system, OCS system component or seat cushion foam pad are needed, a new OCS service kit (seat cushion foam pad, bladder with pressure sensor and OCS module) must be installed as an assembly.

The restraints control module (RCM) checks the OCS circuits for faults. If the RCM detects one of the following faults on any of the OCS circuits, it will store DTC B2290 in memory and, depending on the fault, flash a lamp fault code on the air bag warning indicator.







This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- OCS system component
- Pressure sensing fault
- Module mounting condition
