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.

But, you will need an SRS code reader to reset the Airbag/SRS fault light once done.īoth 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. It'll cost you $2, 6" of electrical tape, and about 10 minutes. Also, the wiring is different in those cars. 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. 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** ).

This short must be released within 25 seconds after the diagnostic monitor tone sounds.ĭiagnostic trouble code is now cleared from memory.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. Release short on Circuit 631 (T/R) to Circuit 57 (BK).Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground.located underneath the glove compartment, left side (06010) containing Circuits 631 (T/R) and 57 (BK). Locate the Diagnostic "Trouble Code Clear" Connector (grey connector).Observe air bag indicator prove-out (six ? two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.Cycle the ignition switch to OFF and then to RUN.Follow the diagnostic procedures to service the fault condition flashing on the air bag indicator prior to code clearing.Reassemble the PAD Module and put it back into the console panel and then put everything back together on the dash in the reverse order of removal.Then you are able to solder on the new LED *polarity matters* with that in mind the negative on the circuit board is closest to the outer edge of the circuit board.Now carefully unsolder the blown light bulb.To prepare the module housing I drilled a 1/4" hole through the clear lens allowing my particular LED to be attached through that hole.Remove circuit board from airbag key module housing.Carefully unclip the plastic tabs that hold the airbag key module case together.Remove 2 phillips head screws to remove the airbag key module.Remove connector from Passenger Airbag Disable module in console panel and take console panel to a work bench.Pull console panel out of the two clips.Using a socket set, remove 4 hex head screws from console panel.
Replace side air bag module (LH).(Before disposal, it must be deployed.).Replace the harness if it has visible damage.Visually check the wiring harness connection.Firing circuit, belt tensioner, passenger's side #4 Airbag Code Repair order ("Recheck SRS at each replacement.")
