P1574 ASCD VEHICLE SPEED SENSOR

P1574 ASCD VEHICLE SPEED SENSOR

Description

INFOID:0000000009753427

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-55, "AUTOMATIC SPEED CONTROL DEVICE (ASCD) : System Description"

 for ASCD

functions.
