NOTE:
•If DTC P0500 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-143
.
•If DTC P0500 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer
to EC-145

The vehicle speed signal is sent to the combination meter from “ABS actuator and electric unit (control unit)”
through CAN communication line. The combination meter then sends a signal to the ECM through CAN com-
munication line.

FAIL-SAFE MODE
When the malfunction is detected, ECM enters fail-safe mode.
DTC Confirmation ProcedureINFOID:0000000001702902
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:
Steps 1 and 2 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.
WITH CONSULT-II
1. Start engine.
2. Read “VHCL SPEED SE” in “DATA MONITOR” mode with CONSULT-II. The vehicle speed on CONSULT-
II should exceed 10 km/h (6 MPH) when rotating wheels with suitable gear position.
If NG, go to EC-392, "
Diagnosis Procedure".
If OK, go to following step.
3. Select “DATA MONITOR” mode with CONSULT-II.

4. Warm engine up to normal operating temperature.
5. Maintain the following conditions for at least 60 consecutive seconds.
6. If 1st trip DTC is detected, go to EC-392, "
Diagnosis Procedure".
Overall Function CheckINFOID:0000000001702903
Use this procedure to check the overall function of the vehicle speed signal circuit. During this check, a 1st trip
DTC might not be confirmed.
WITH GST
1. Lift up drive wheels.
2. Start engine.
3. Read vehicle speed signal in Service $01 with GST.
The vehicle speed signal on GST should be able to exceed 10 km/h (6 MPH) when rotating wheels with
suitable gear position.
4. If NG, go to EC-392, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001702904
1.CHECK DTC WITH “ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)”
Refer to BRC-8
.
OK or NG
OK >> GO TO 2.
NG >> Repair or replace.

DTC P1574 ASCD VEHICLE SPEED SENSOR
Component DescriptionINFOID:0000000001702965
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
for ASCD functions.
On Board Diagnosis LogicINFOID:0000000001702966
This self-diagnosis has the one trip detection logic.
The MIL will not light up for this diagnosis.
NOTE:
•If DTC P1574 is displayed with DTC U1000, U1001, first perform the trouble diagnosis for DTC U1000,
U1001. Refer to EC-143
.
•If DTC P1574 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer
to EC-145
.
•If DTC P1574 is displayed with DTC P0500, first perform the trouble diagnosis for DTC P0500. Refer
to EC-391
.
•If DTC P1574 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer
to EC-397
.
DTC Confirmation ProcedureINFOID:0000000001702967
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.
WITH CONSULT-II
1. Start engine.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Drive the vehicle at more than 40 km/h (25MPH).
4. If DTC is detected, go to EC-448, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-II” above.
