Which does
“TESTING” change to?
COMPLETED>>GO TO 6.
OUT OF CONDITION>>Retry DTC CONFIRMATION PROCEDURE. GO TO 4.
6.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-III
Touch “SELF-DIAG RESULT”
Which is displayed on CONSULT-III screen?
YES >> INSPECTION END
NO >> Go to EC-188, "
Diagnosis Procedure".
7.PERFORM COMPONENT FUNCTION CHECK FOR MALFUNCTION B
Perform Component Function Check. Refer to EC-186, "
Component Function Check".
NOTE:
Use component function check to check the overall function of the A/F sensor 1 circuit. During this check, a
1st trip DTC might not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-188, "
Diagnosis Procedure".

P1805 BRAKE SWITCH
DescriptionINFOID:0000000005930058
Brake switch signal is applied to the ECM through t
he stop lamp switch when the brake pedal is depressed.
This signal is used mainly to decrease the engine speed when the vehicle is driving.

DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch ON.
2. Fully depress the brake pedal for at least 5 seconds.
3. Erase DTC. Refer to “SELF-DIAGNOSTIC RESULTS MODE”, “How to Erase Self diagnostic Results” in
EC-103, "
On Board Diagnosis Function" (Without CONSULT-III) or EC-106, "CONSULT-III Function" (With
CONSULT-III).
4. Check 1st trip DTC.
Is 1st trip DTC detected?
