P1805 BRAKE SWITCH

Description

INFOID:0000000001056434

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.

2.

Fully depress the brake pedal for at least 5 seconds.

3.

Erase the DTC with CONSULT-III.

4.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Go to 

EC-277, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000001056436

1.

CHECK STOP LAMP SWITCH CIRCUIT

1.

Turn ignition switch OFF.

2.

Check the stop lamp when depressing and releasing the brake pedal.

Is 1st trip DTC detected?

YES

>> GO TO 4.

NO

>> GO TO 2.

2.

CHECK STOP LAMP SWITCH POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect stop lamp switch harness connector.

3.

Check the voltage between stop lamp switch harness connector and ground.
