Abs Electronic Control Unit
The ABS Electronic Control Unit (ECU) controls, monitors and provides failure diagnostics for Anti-Lock Brake System (ABS) and Electronic Traction Control (ETC) systems. In addition to ABS and ETC system control, the ABS ECU uses wheel speed sensor input to generate a digital road speed signal which it sends it to the Body Electric Control Module (BECM) and a rough road signal which it sends to the Engine Control Module (V8 engines only). The ABS ECU is located on the passenger-side dash board, behind an access plate. The ABS ECU is not serviceable and is connected to the ABS electrical harness by 9-pin, 15-pin and 18-pin connectors.
