Caddy Tension

Some owners of 2010 Cadillac DTS vehicles may comment that the airbag light is illuminated. The technician may find DTC B0071 set in the PPS (passenger presence system) and DTC B0081 in the sensing and diagnostics module (SDM).

Do not replace the PPS or SDM. Verify proper system electrical connections. Inspect the passenger seat belt tension sensor signal, voltage reference and low reference circuits, and inspect the cutting/chafing for DTC B0071. If all checks have been made and no fault has been found, replace the belt tension sensor.

NOTE: The seat belt tension sensor is not serviced separately. The seat belt buckle wit the tension sensor must be serviced as a complete unit.
