Condition
Some customers may comment on the airbag light being illuminated. Upon investigation, the technician may find DTC B0071 set in the passenger presence system (PPS) and a DTC B0081 in the sensing and diagnostics module (SDM).
Correction
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.
