Diagnosis Procedure
Regarding Wiring Diagram information, refer to WCS "Wiring Diagram".
1. CHECK FUSE
Check if the key switch 10A fuse [No. 8, located in the fuse block (J/B)] is blown.
Is the fuse blown?
YES >> Replace the fuse after repairing the affected circuit.
NO >> GO TO 2
2. CHECK BCM INPUT SIGNAL
Check voltage between BCM harness connector M18 terminal 37 and ground.
Is the inspection result normal?
YES >> Inspection End.
NO >> GO TO 3
3. CHECK KEY SWITCH CIRCUIT
1. Disconnect BCM connector M18 and key switch.
2. Check continuity between BCM harness connector M18 terminal 37 and key
switch harness connector
M27 terminal 1.
3. Check continuity between BCM harness connector M18 terminal 37 and ground.
Is the inspection result normal?
YES >> GO TO 4
NO >> Repair or replace harness.
4. CHECK KEY SWITCH POWER SUPPLY CIRCUIT
Check voltage between key switch harness connector M27 terminal 2 and ground.
Is the inspection result normal?
YES >> Replace key switch.
NO >> Repair or replace harness.
Component Inspection
1. CHECK KEY SWITCH
1. Turn ignition switch OFF.
