Component Description

The ECM receives two vehicle speed signals via CAN communication line. One is sent from "ABS actuator and electric unit (control unit)" or combination meter, and the other is from TCM (Transmission control module). The ECM uses these signals for ASCD control. Refer to AUTOMATIC SPEED CONTROL DEVICE (ASCD) for ASCD functions.
