P1574 ASCD vehicle speed sensor

Description

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