DTC P1805 BRAKE SWITCHPFP:25320
DescriptionEBS00M9U
Brake switch signal is applied to the ECM through the stop lamp switch when the brake pedal is depressed.
This signal is used mainly to decrease the engine speed when the vehicle is driving.
CONSULT-II Reference Value in Data Monitor ModeEBS00M9V
Specification data are reference values.
ECM Terminals and Reference ValueEBS00M9W
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
On Board Diagnosis LogicEBS00M9X
The MI will not light up for this diagnosis.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters in fail-safe mode.
DTC Confirmation ProcedureEBS00M9Y
WITH CONSULT-II
1. Turn ignition switch “ON”.
2. Fully depress the brake pedal for at least 5 seconds.
3. Erase the DTC with CONSULT-II.
