Diagnosis Procedure

INFOID:0000000009645385

Regarding Wiring Diagram information, refer to 

DLK-199, "Wiring Diagram"

.

1.

CHECK KEY SWITCH INPUT SIGNAL

With CONSULT

Check key switch "KEY ON SW" in DATA MONITOR mode with CONSULT. Refer to 

DLK-196, "DOOR LOCK

: CONSULT Function (BCM - DOOR LOCK)"

.

• When key is inserted to ignition key cylinder:

• When key is removed from ignition key cylinder:

Without CONSULT

Check voltage between BCM connector M18 terminal 37 and ground.

Is the inspection result normal?

YES

>> Key switch (insert) circuit is OK.

NO

>> GO TO 2

2.

CHECK KEY SWITCH (INSERT)

1. Turn ignition switch OFF.

2. Disconnect key switch connector.

3. Check continuity between key switch terminals.

Is the inspection result normal?

YES

>> Repair or replace harness or fuse.

NO

>> Replace key switch.
