The vehicle speed signal is transmitted from the Anti-Lock Brake System (ABS) actuator and electric unit (control unit) to Transmission Control Module (TCM) via Control Area Network (CAN) communication line. The Diagnostic Trouble Code (DTC) will set when there is a big difference between the vehicle speed signal from the ABS actuator and the electric unit (control unit), and the vehicle speed sensor signal.
