The owner of a 2006-07 Saab 9-7X model may come into your store with a complaint of an illuminated airbag light. When that happens, hook up your scan tool and check for trouble codes in the SRS module. If the only code you see is DTC 023, there's a good chance the right seatbelt tension sensor is at fault, reports Saab.
To make the correct diagnosis, check the wiring to the tension sensor for cuts or chafing. If everything looks OK, the sensor is the most likely culprit. Replacing the entire right seatbelt retractor (the tension sensor is not available separately) should prevent further airbag troubles. Check with a dealer for the part number of the retractor.
