DTC P1572 ICC BRAKE SWITCH
DTC P1572 ICC BRAKE SWITCH
Component DescriptionINFOID:0000000001326935
When the brake pedal is depressed,
ICC 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 ACS-7
for the ICC function.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001326936
Specification data are reference values.
On Board Diagn osis LogicINFOID:0000000001326937
This diagnosis has the one trip detection logic.
The MIL will not light up for this diagnosis.
NOTE:
If DTC P1572 is displayed with DTC P0605, first pe rform the trouble diagnosis for DTC P0605. Refer
to EC-1007
.
 This self-diagnosis has the one tr ip 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 igniti on switch OFF. And even when ma lfunction A is detected in two
consecutive trips, DTC is not stored in ECM memory.
DTC Confirmation ProcedureINFOID:0000000001326938
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
 If DTC Confirmation Procedure has been previously conduc ted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
