Rick's Free Auto Repair Advice

GM vehicles with B0071 or B0081 trouble codes.

If you own one of the vehicles listed below and see a lit SRS (supplemental restraint system) light on your dash, you may have one or both of these trouble codes: B0071 or B0081. Both codes relate to a problem in the Sensing and Diagnostics module. Don’t start replacing air bad components like the clock spring or the module. The problem is most likely the result of a defective seat belt tensioner sensor located in the passenger side seat belt buckle. Contact the dealer for the updated sensor and install it. That should clear the code.
