How to Reset a Saab SRS Fault

Save

In 1989 Saab was the first car manufacturer to offer a Supplemental Restraint System, or SRS as standard in its 900 model. The system included two airbags, one located in the steering wheel to protect the driver and another in the dash designed for the front seat passenger. Since then, SRS systems have become the industry norm. Because the technology was new, SRS failure lights are a common annoyance for owners of many Saab's made through out the 1990s. While many are false alarms and can be fixed simply, others can be serious and should be addressed by a mechanic only.

Things You'll Need

  • Adjustable Wrench
  • Sand Paper
  • Rubber Gloves

Disconnecting the Battery

  • Set the hand brake, remove the key from the ignition switch, and open the hood.

  • Disconnect the negative battery lead from the battery terminal using the adjustable wrench first, then disconnect the positive lead. Usually the negative lead is black and the positive lead is red.

  • Put on the rubber gloves. Sand the battery terminals and leads until they appear shiny and there is no noticeable corrosion left.

  • Reconnect the battery leads using the adjustable wrench. Close the hood and turn on the car to see if the SRS light has been turned off. Take the car for a short test drive to see if it comes back on.

Tips & Warnings

  • If there is actually a fault in the SRS Light, it can only be permanently reset by independent shops that own an airbag tester once the problem is fixed.
  • The majority of SRS lights are cause by the horn contact rings. This ring is located behind the steering wheel. The dealer fault code is 2D on an airbag tester. Replacement of the horn contact reel should be performed by authorized personnel only due to the technical nature and the possibility of Airbag Deployment. Deployment of an airbag can not only be extremely dangerous but may also result in your car being deemed totaled and unfit for the road in certain states, whether you replace the airbag or not.
