M.B. Doc ASR Light Remains On?
I am in need of a diagnosis of a ASR Light remaining on with the engine running on my 92 500E. The ASR system appears to operate correctly, to test it I have floored it and get wheel spin for only about 5 to 10 ft, then the ASR warning light with the Triangle in the Speedometer with come on and the spinning stops.
Is this the correct operation? From what I have learned, this is how it should work. What could cause the ASR light to stay on?
1. Faulty ABS sensor in one of the rear wheels?
2. Faulty ASR module?
3. Short in the light circuit?
I've no CD or manual at this point but would prefer to do any work I can myself, any help would be most appreciated before it goes to the shop next week.
