P1572 ASCD BRAKE SWITCH
P1572 ASCD BRAKE SWITCH
DescriptionINFOID:0000000001693379
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 this input of two kinds (ON/OFF signal).
Refer to EC-424, "
System Diagram" for the ASCD function.
DTC LogicINFOID:0000000001693380
DTC DETECTION LOGIC
NOTE:
If DTC P1572 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer
to EC-524, "
DTC Logic".
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 CONFIRMATION PROCEDURE
1.INSPECTION START
Do you have CONSULT-III?.
Do you have CONSULT-III?
YES >> GO TO 2.
NO >> GO TO 5.
2.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
NOTE:
Procedure for malfunction B is not described here. It takes extremely long time to complete procedure for mal-
function B. By performing procedure for malfunction A, the incident that causes malfunction B can be
detected.
>> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-I
With CONSULT-III
1. Start engine.
2. Select “DATA MONITOR” mode with CONSULT-III.
3. Press MAIN switch and make sure that CRUISE indicator is displayed in combination meter.
4. Drive the vehicle for at least 5 consecutive seconds under the following conditions.
CAUTION:
