ASCD BRAKE SWITCH

Description

INFOID:0000000001056487

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-60, "System Description"

for the ASCD function.

Without CONSULT-III

1.

Turn ignition switch ON.

2.

Check the voltage between ECM harness connector and ground.

Is the inspection result normal?

YES

>> INSPECTION END.

NO

>> Go to
