Seatbelt Throws Airbag Light

Owners of 2007-2010 Cadillac Escalade vehicles may comment that the air bag light is 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).

Diagnose and replace the right front seatbelt buckle if necessary. 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 for cutting and/or chafing. If all checks have been made and no fault has been found, replace the belt tension sensor.

Note that the seat belt tension sensor is not serviced separately. The seat belt buckle with the tension sensor must be serviced as a complete unit.
