If you have an Airbag/SRS red light on your dash and the code comes back to either (or both) the passenger or driver side seat belt buckle switch, here's how you can fix it for good. From the best I can tell this DIY will only apply to 318ti cars made in June 1997 and earlier (** or even earlier, see responses below** ). It looks like in July 1997 the 318ti got the updated 'hall effect' belt buckle switch which was more reliable, so you probably don't have this issue. Also, the wiring is different in those cars.

I have a permanent airbag light and have a code reader. I tried to reset the light but it stays on. The codes read; - firing circuit, belt tensioner, drivers side - firing circuit, belt tensioner, passenger side - firing circuit, passenger airbag, stage 2. Any ideas on how to resolve this? Share this post on; Digg. Firing circuit, belt tensioner, driver's side. Firing circuit, belt tensioner, passenger's side. Firing circuit, passenger's airbag. Warning 1: Codes can be misleading and there may also be errors in this manual. Never depend solely on fault codes for diagnosis. Warning 2: Most SRS repairs require a BMW factory.

FSX Beechcraft 1900D. It'll cost you $2, 6' of electrical tape, and about 10 minutes. But, you will need an SRS code reader to reset the Airbag/SRS fault light once done.

Both selt belt buckle switches are designed to provide the SRS computer with either 100 ohms resistance if the seat belt is latched, or 400 ohms if the seat belt is unlatched. We are going to simply add a 100 ohm resistor into the system to make the airbag computer think the seat belts are always latched. This bypasses the faulty buckle switches in pre July 1997 models which triggers the airbag light. Mine would randomly come on every few months and I was getting both the driver and passenger side codes. Supplies: • Radio Shack #271-1108. 5 pack, 100 ohm Resistors. 1/2 watt, 5% tolerance.
