Quick restatement of an unsolved problem: I simulatenously lost speedometer and got constant instrument indicators for ABS, brake pads, and parking brake.
Made some progress with this problem. I bought the C220 full schematics on e-bay and I discovered that the ABS, Brake Pad, and Parking Brake (for fluid failure) are all controlled from the ABS module. Moreover, the speedometer signal is also routed through the ABS module before going to the instrument panel. Quite a coincidence!!!
That is, I strongly suspect the ABS control unit. The problem is that the schematics tell me that the ABS control unit is located next to the cruise control and ECU modules in the engine compartment. I did not find it!
Anyone knows where the ABS module is located on a 1996 C220?
