Test I: DTC B2290 - Occupant Classification System Fault
PINPOINT TEST I: DTC B2290 - OCCUPANT CLASSIFICATION SYSTEM FAULTLamp Fault Codes (LFC)
The following lamp fault codes (LFCs) indicate the specific faults 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 occupant classification system module [OCSM]) 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 system service kit (seat cushion foam pad, bladder with pressure sensor and OCSM) must be installed as an assembly.
The restraints control module (RCM) checks with the OCSM for faults. If the OCSM 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 LFC 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
- OCSM mounting condition
