Do This | Don't Do This |
---|---|
Diagnose and replace right front seatbelt buckle, if necessary. | Do not replace the passenger presence system or the sensing and diagnostic module. |
Verify proper system electrical connections. Inspect the passenger seat belt tension sensor signal, voltage reference, and low reference circuits carefully for cutting and/or chaffing per SI instructions for DTC B0071. If all checks have been made and no fault has been found, replace the belt tension sensor.
Important: The seat belt tension sensor is not serviced separately. The seat belt buckle with the tension sensor must be serviced as a complete unit.
