P1572 ASCD BRAKE SWITCH
DescriptionINFOID:0000000009462775
When the brake pedal is depressed, brake pedal position 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-574, "AUTOMATIC SPEED CONTROL DE VICE (ASCD) : System Description"
for the ASCD
function.

NOTE:
• If DTC P1572 is displayed with DT C P0605, first perform the trouble diagnosis for DTC P0605. Refer
to EC-883, "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 igniti on switch OFF. And even when ma lfunction A is detected in two
consecutive trips, DTC is not stored in ECM memory.
