ASCD BRAKE SWITCH
ASCD BRAKE SWITCH
DescriptionINFOID:0000000001693416
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 Description" for the ASCD function.
Component Function CheckINFOID:0000000001693417
1.CHECK FOR ASCD BRAKE SWITCH FUNCTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “BRAKE SW1” in “DATA MONITOR” mode with CONSULT-III.
3. Check “BRAKE SW1” indication under the following conditions.
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 EC-588, "
Diagnosis Procedure".
