DTC P1574 ASCD VEHICLE SPEED SENSORPFP:31036
Component DescriptionUBS00QLT
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-28, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)" for ASCD functions.
