Hi,
My father has a 1996 C250 Classic Diesel Saloon (UK Market). The ABS light is on all the time whilst driving and the spedometer does not work. I was wondering if these are related. Does this model use the ABS wheel sensors to generate a signal for the spedometer, and if so which one (or all)? Anything else it might be? What would I need to diagose a faulty sensor? I have a DVM and oscilloscope, but what signals / voltages should be present.
Many thanks in advance of any reply,
Jon Symonds
