Key Warning Chime Does Not Operate

Check if the key switch and key lock solenoid (key detection) switch fuse is blown. Refer to "WIRING DIAGRAM-CHIME -- ".

Is the fuse blown? 

• YES: If fuse is blown, be sure to eliminate cause of problem before installing new fuse. Refer to "POWER SUPPLY ROUTING CIRCUIT ".
• NO: GO TO 2.

With key removed from the ignition and the front door LH open, turn the lighting switch to 1st or 2nd position.

Does warning chime sound? 

• YES: GO TO 3.
• NO: Go to "ALL WARNINGS ARE NOT OPERATED " or "KEY WARNING CHIME AND LIGHT WARNING CHIME DOES NOT OPERATE (SEAT BELT WARNING CHIME DOES OPERATE) ".
