Test I: LFC 16/DTC B2290 - Occupant Classification System Fault
PINPOINT TEST I: LFC 16/DTC B2290 - OCCUPANT CLASSIFICATION SYSTEM FAULTNOTE: LFC 16 is shared between DTC B2290 and DTC B2909.
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 restraints control module (RCM) monitors for fault conditions reported by the occupant classification system module (OCSM). If the RCM detects one of the following faults reported by the OCSM, it will store DTC B2290 in memory and flash LFC 16 (or higher priority code if one exists) on the air bag warning indicator.
The OCS system components (seat cushion foam pad, bladder with pressure sensor, OCSM and seat wiring harness) are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately. If a OCS system component or seat cushion foam pad are needed, a new OCS system service kit (seat cushion foam pad, bladder with pressure sensor, OCSM and seat wiring harness) must be installed as an assembly.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- OCS system component
- RCM
