Test D: DTC B2290 - Occupant Classification System Fault

PINPOINT TEST D: DTC B2290 - OCCUPANT CLASSIFICATION 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 system module (OCSM). Refer to the Supplemental Restraints System (SRS) DTC Chart when DTC B2290 is reported by the RCM for diagnostic instructions. Diagnostic Trouble Code Tests and Associated Procedures
- The following pinpoint test must only be used to diagnose DTC B2290 when reported by the OCSM.

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 OCSM monitors the 2 OCS rails (weight sensors) and circuitry for faults. If the OCSM detects a fault with the sensor(s) 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 (IC) module to illuminate the air bag warning indicator.
