It would be great to do this kind of thing with a $1.49 16-pin PIC microcontroller, a $0.49 7-segment display, and a $0.75 1"x1" piece of proto board.Ħ5771382905 Control unit airbag From: To:. Send me the instructions you have, maybe I can translate (electrially). I remember doing something with a wire and the OBD port to reset the oil/service interval light too. Just wanna make sure there is only one jumper wire needed.Įither the #15 pin in the round OBD port under the hood, OR the alternative pin #6 of the x74 orange connector under glovebox. Legoman, can you see what I wrote in color and clarify for me please. After five seconds, disconnect the jumpers (I'm assuming you mean only one jumper either Pin #15 of the round OBD port under the hood, OR the alternative Pin #6 of the orange x74 connector behind glove box, and not 2 jumpers?. Reconnect the jumper to ground pin #6 (or from pin #15 in the round OBD port under the hood?).ħ. After five seconds, disconnect the jumper.Ħ. The light does not clear, there is most likely a problem with the air bag systemĤ.
If the light does not clear repeat the procedure. The air bag warning light should clear after approximately 10 Turn the ignition switch to the on (run) position but, do not start the car.ġ2. Ground.(Since this is awkward to do in the timing given in this procedure, i used a small screwdriver and tapped into pin 6 at the orange x74 connector behind the glovebox, either will work)ģ. Install a jumper from in pin #15 of the engine diagnostic connector to
Turn the ignition switch to the off position.Ģ. This worked for mine even when DIS/INPA/Autologic, and all those others failed to communicate.ġ. This module is also found in some E23,e24,e30,e32,e34, and e36, procedure should work for those as well. This only works on Early E31, start of production to 09/93 With SIEMENS 5WK4 027 (65771382905) modules.
