Had front brake pads and rotors replaced. Next day ABS light on dash came on. Took car to dealer .Dealer said front left speed sensor gone. Dealer replaced speed sensor. Same day car picked up from shop light on again.Bring car back to dealer. Now dealer says EBCM gone and will cost $855.00 to fix!! Question: I have a 1993 Chevy Cavalier with the same Delco ABS-VI system. Does anyone know if the EBCM's are interchangable? Please reply. Thanks
