The Occupant Classification System Module (OCSM) monitors the pressure sensor and internal circuitry for faults. If a fault is detected, the OCSM stores DTC B2290 in memory and sends a message to the Restraints Control Module (RCM). The RCM then stores DTC B00A0:09 in memory and sends a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.
The Occupant Classification System (OCS) components must not be installed separate from the seat cushion or heater mat (if equipped).
DTC C1941 sets when System Reset fails to complete the testing. DTC C1941 will clear upon a successful System Reset.
- DTC B2290 Occupant Classification System (OCS) Fault - This DTC sets if the OCSM detects a fault in the bladder pressure sensor (integrated with the OCSM).
- DTC C1941 Zero Seat Weight Test Failure - This DTC will set if the OCSM is unable to complete a successful System Reset. All other OCS DTCs must be diagnosed and repaired before carrying out the OCS reset.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Faulted OCS
- OCS bladder installation
