INFOID:0000000009878781
Regarding Wiring Diagram information, refer to
DLK-76, "Wiring Diagram - King Cab"
.
1.
CHECK KEY SWITCH INPUT SIGNAL
With CONSULT
Check key switch "KEY ON SW" in DATA MONITOR mode with CONSULT. Refer to
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 circuit is OK.
NO
>> GO TO 2
2.
CHECK KEY SWITCH
1. Turn ignition switch OFF.
2. Disconnect key switch connector.
3. Check continuity between key switch terminals 3 and 4.
Is the inspection result normal?
YES
>> GO TO 3
NO
>> Replace key switch.
3.
CHECK KEY SWITCH CIRCUIT
