DTC P1564 ASCD STEERING SWITCH
DTC P1564 ASCD STEERING SWITCH
Component DescriptionINFOID:0000000001702951
ASCD steering switch has variant values of electrical resistance for each button. ECM reads voltage variation
of switch, and determines which button is operated.
Refer to EC-28
for the ASCD function.
CONSULT-II Reference Value in Data Monitor ModeINFOID:0000000001702952
Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001702953
This self-diagnosis has the one trip detection logic.
The MIL will not light up for this diagnosis.
NOTE:
If DTC P1564 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605.

DTC P1572 ASCD BRAKE SWITCH
DTC P1572 ASCD BRAKE SWITCH
Component DescriptionINFOID:0000000001702958
When the brake pedal is depressed, ASCD brake switch (2) is
turned OFF and stop lamp switch (1) is turned ON. ECM detects the
state of the brake pedal by this input of two kinds (ON/OFF signal).
Refer to EC-28
for the ASCD function.

NOTE:
•If DTC P1572 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer
to EC-397
.
•This self-diagnosis has the one trip detection logic. When malfunction A is detected, DTC is not
stored in ECM memory. And in that case, 1st trip DTC and 1st trip freeze frame data are displayed.
1st trip DTC is erased when ignition switch OFF. And even when malfunction A is detected in two
consecutive trips, DTC is not stored in ECM memory.

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.

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.
