DTC P1574 ASCD VEHICLE SPEED SENSOR
DTC P1574 ASCD VEHICLE SPEED SENSOR
Component DescriptionINFOID:0000000006342136
The ECM receives two vehicle speed signals via CAN co
mmunication line. One is sent from "ABS actuator
and electric unit (control unit)" or combination meter, and the other is from TCM (Transmission control mod-
ule). The ECM uses these signals for ASCD control. Refer to EC-523
for ASCD functions.
On Board Diagnosis LogicINFOID:0000000006342137
NOTE:
•If DTC P1574 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
• If DTC P1574 is displayed with DTC P0500, first perform the trouble diagno sis for DTC P0500. Refer
to EC-887
.
• If DTC P1574 is displayed with DTC P0605, first perform the trouble diagno sis for DTC P0605. Refer
to EC-895
.
• If DTC P1574 is displayed with DTC P0607, first perform the trouble diagno sis for DTC P0607. Refer
to EC-897
.
This self-diagnosis has the one trip detection logic.
The MIL will not light up for this diagnosis.
DTC Confirmation ProcedureINFOID:0000000006342138
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Step 3 may be conducted with the drive wheels 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.
1. Start engine.
2. Drive the vehicle at more than 40 km/h (25MPH).
3. Check DTC.
4. If DTC is detected, go to EC-940, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000006342139
