5. CHECK KEY SWITCH CIRCUIT
1. Disconnect BCM connector.
2. Check continuity between BCM harness connector M3 terminal 37 (B/W) and key switch harness connector M23 terminal 1 (B/
W).
3. Check continuity between BCM harness connector M3 terminal 37 (B/W) and ground.
OK or NG
OK >> GO TO 6.
NG >> Repair harness or connector.
6. CHECK KEY SWITCH POWER SUPPLY CIRCUIT
Check voltage between key switch harness connector M23 terminal
2 (L/R) and ground.
OK or NG
OK >> Replace BCM. Refer to BCS-16, "Removal and Installa-
tion of BCM" .
NG >> Check harness between key switch and fuse.
Key Warning Chime Does Not Operate (With Intelligent Key, When Mechanical
Key Is Used)
AKS0079U
1. CHECK FUSE
Check if the key switch and ignition knob switch 10A fuse (No. 38, located in the fuse and fusible link box) is
blown. Refer to DI-63, "
Wiring Diagram — CHIME —" .
Is the fuse blown?
YES >> Replace fuse. Be sure to repair the cause of malfunction before installing new fuse.
NO >> GO TO 2.
2. CHECK WARNING CHIME OPERATION
Check the chime under conditions in exception of key warning chime (when mechanical key is used) opera-
tion.
Does warning chime sound?
YES >> GO TO 3.
NO >> Go to DI-71, "
All Warnings Are Not Operated" or DI-72, "Key Warning Chime and Light Warning
Chime Does Not Operate (Seat Belt Warning Chime Does Operate)" .
37 (B/W) – 1 (B/W) : Continuity should exist.
37 (B/W) – Ground : Continuity should not exist.
