ASR/ABS lights on with bumps
My 94 SL600 recently died on me (carried to dealer on flat bed, started right up on arrival) It had been flashing the ASR/ABS lights infrequently when going over rough spots.
Dealer techs found loose connection back by the battery. (Modules talking to modules wiring). Un plugged and replugged connections, fixed the problem. Cost $371 with tow.--flat charge to connect to diagnostic computer + 1 hr charge to clean and resecure all connections.
You have been warned. When it comes loose, the engine dies and will not fire. (Always on rainy nite in bad neighborhood) ONSTAR works great.
