Service Diagnosis

1. Verify it any DTCs are present. Upon investigation, the technician may find DTC B0022 present/stored in history.

2. If this DTC is present, inspect the SIR coil connection to the cross-body harness. Verify this by removing the knee bolster below the steering column to access this connection. Disconnect the connector. On the female side of the connector, the shorting bar may be crushed, which may be shorting the circuit. The shorting bar is located between the two female terminals on the connector.

Correction

If the diagnosis leads to a damaged SIR coil connection, replace the SIR coil in the steering column. Refer to the Inflatable Restraint Steering Wheel Module Coil Replacement procedure (SI Document ID # 825475).
