E SPEED SENSOR
P1574 ASCD VEHICLE SPEED SENSOR
DescriptionINFOID:0000000009462782
The ECM receives two vehicle speed signals via CAN communication line. One is sent from combination
meter, and the other is from TCM (Transmission contro l module). The ECM uses these signals for ASCD con-
trol. Refer to EC-574, "AUTOMATIC SPEED CONTROL DE VICE (ASCD) : System Description"
for ASCD
functions.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-
ing the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine (VDC switch OFF).
2. Drive the vehicle at more than 40 km/h (25 MPH). CAUTION:
Always drive vehicle at a safe speed.
NOTE:
This procedure may be conducted with the drive wheel s lifted in the shop or by driving the vehicle.
If a road test is expected to be easier , it is unnecessary to lift the vehicle.
