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

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

NOTE: DTC B2290 reported by the restraints control module (RCM) is informational only and indicates the presence of a fault in the occupant classification sensor (OCS) system. Refer to the Supplemental Restraints System (SRS) DTC Chart when DTC B2290 is reported by the RCM for diagnostic instructions. The following pinpoint test must only be used to diagnose DTC B2290 when reported by the OCS system. Diagnostic Trouble Code Tests and Associated Procedures

Normal Operation
The OCS is used to classify the front passenger seat occupant in the event of a deployable impact.

The occupant classification system module (OCSM) monitors the pressure sensor and circuity for faults. If the OCSM detects a fault with the sensor or circuitry, it will store DTC B2290 in memory and send a message to the RCM which will store DTC B2290 in memory and send a message to the instrument cluster to flash LFC 16 (or higher priority code if one exists) on the air bag warning indicator.

The OCS components (seat cushion foam pad, bladder with pressure sensor and OCSM) are calibrated to each other and are serviced as an assembly. The OCS components are not to be installed separately. If a new OCS service kit is to be installed, it must be installed as an assembly.







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