P1574 ASCD VEHICLE SPEED SENSOR
DescriptionINFOID:0000000009462383
The ECM receives two vehicle speed sensor signals via CAN communication line. One is sent from combina-
tion meter, and the other is from TCM (Transmission control module). The ECM uses these signals for ASCD
control. Refer to EC-63, "AUTOMATIC SPEED CONTROL DE VICE (ASCD) : System Description"
for ASCD
functions.
