P1572 ASCD BRAKE SWITCH
Description
INFOID:0000000003388168
When the brake pedal is depressed, ASCD brake switch is turned OFF and stop lamp switch is turned ON.
ECM detects the state of the brake pedal by those two types of input (ON/OFF signal).
Refer to
for the ASCD function.

INFOID:0000000003388169
DTC DETECTION LOGIC
NOTE:
• If DTC P1572 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer
• 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 is turned OFF. And even when malfunction A is detected
in two consecutive trips, DTC is not stored in ECM memory.
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.
NOTE:
The procedure for malfunction B is not described. It takes extremely long time to complete the procedure for
malfunction B. By performing the procedure for malfunction A, the condition that causes malfunction B can be
detected.
>> GO TO 2.
2.
PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT-III
1.
Start engine (VDC switch OFF).
2.
Select “DATA MONITOR” mode with CONSULT-III.
3.
Press MAIN switch and check that CRUISE illuminates.
4.
Drive the vehicle for at least 5 consecutive seconds under the following conditions.
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
This procedure 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.

Description
INFOID:0000000003388181
ECM receives two vehicle speed signals via the CAN communication line. One is sent from “ABS actuator and
electric unit (control unit)” via combination meter, and the other is from TCM (Transmission control module).
ECM uses these signals for engine control.
