DTC P1572 ASCD BRAKE SWITCH
Component DescriptionINFOID:0000000005532803
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-522
for the ASCD function.
CONSULT-III Reference Val ue in Data Monitor ModeINFOID:0000000005532804
Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005532805
This self-diagnosis has the on e trip detection logic.
The MIL will not light up for this diagnosis.
NOTE:
• If DTC P1572 is displayed with DT C P0605, first perform the trouble diagnosis for DTC P0605. Refer
to EC-893
.
• 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 ma lfunction A is detected in two
consecutive trips, DTC is not stored in ECM memory.

DTC Confirmation Procedure
INFOID:0000000005532806
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.
• Procedure for malfunction B is not described here. It takes extremely long time to complete procedure for
malfunction B. By performing procedure for malfunction A, the incident that causes malfunction B can be
detected.
TESTING CONDITION:
Steps 3 and 6 may be conducted with the drive wheels li fted 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-III
1. Start engine.
2. Press MAIN switch and make sure that CRUISE indicator lights up.
3. Drive the vehicle for at least 5 consecutive seconds under the following condition.
4. Check 1st trip DTC.
5. If 1st trip DTC is detected, go to EC-934, "
Diagnosis Procedure".
If 1st trip DTC is not detec ted, go to the following step.
6. Drive the vehicle for at least 5 consecutive seconds under the following condition.
7. Check 1st trip DTC.
8. If 1st trip DTC is detected, go to EC-934, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III” above.
Vehicle speed More than 30 km/h (19 MPH)
Shift lever Suitable position
Vehicle speed More than 30 km/h (19 MPH)
Shift lever Suitable position
Driving location Depress the brake pedal for more than 5
seconds so as not to come off from the
above-mentioned vehicle speed.
