Service ASR light
My 96 started showing "Service ASR" and ASR Off" lights. No 'current' codes, but a CODE 65 showed up in the 'history'.
A friend and I went through the trouble-shooting chart in the Service Manual (pretty confusing!!), traced wires back to the ASR/ABS computer behind driver's seat (continuity, etc); found no problems.
Any ideas on the next step(s)?
Thanks for any help.

If the light is on you have a code. It isnt a OBD2 code so it will come clean there. You need the ABS scanner tool. They have it dealers and local parts stores.
If you got it scanned that way and it still doesnt pop a code. Do you hear any unusual noise? Check the wheel bearing wires, if they get worn or pinched it will trip your ASR.

No unusual noises when the light came on. I seem to remember that I got on the gas hard (because it felt good!) and the light came on. Wires at the wheels that I can see look good.
I did get a CODE 65 to show up in the code 'history'. I'll get the ABS scanner (been using a Snap-on code reader, but not sure about ABS scanning capabilities).
Thanks.

You are correct about the Code 65 being the "Adjuster Assembly Fault". I have the 96 FSM, but I don't know if I agree about the diagnosis tree being "easy to follow". Is this "fault" a mechanical problem - cable slipped inside the ASR unit (it doesn't look like it has moved) or an electrical one? One thing my friend and I noticed was that the voltage at the ASR is different in my 96 than in his 96; mine shows about 2 volts and his shows 12.5. We traced wires back to the ASR/ABS computer and all seems ok (continuity, voltage both at 12+ volts), but the voltage difference seems to be a clue.
I would like to swap the ASR part of the computer with his, but am hesitant about whether separating the computer will result in a lot of brake fluid leakage. Any ideas about that?
Thanks

Its the part under the hood. Driver side and it says asr on the top plastic. Not sure what your issue is but if its that I got one for ya.
