Check Ignition Switch Illumination

Step	Check	Yes	No
1 CHECK IGNITION CIRCUIT . Check the ignition circuit. Ref. to CHECK IGNITION SWITCH CIRCUIT , INSPECTION, Security System.	Is the switch circuit normal?	Go to step 2 .	Repair or replace.
2 CHECK DOOR SWITCH CIRCUIT . Inspect door switch circuit. Ref. to CHECK DOOR SWITCH , INSPECTION, Keyless Entry System.	Is the switch circuit normal?	Go to step 3 .	Repair or replace.
3 CHECK FUSE . Remove and visually check fuse No. 14 (in the main fuse box).	Is the fuse blown out?	Replace the fuse with a new part.	Go to step 4 .
4 CHECK HARNESS . Disconnect the ignition switch illumination connector. NOTE: The ignition switch illumination is integrated into the immobilizer antenna. Measure the voltage between ignition switch illumination connector and chassis ground. Connector & terminal (B415) No. 2 (+) - Chassis ground (-):	Is the voltage 10 V or more?	Go to step 5 .	Check the harness for open or short circuits between the ignition switch illumination and fuse.
5 CHECK IGNITION SWITCH ILLUMINATION CIRCUIT . Disconnect the connector of body integrated unit. Check the harness between body integrated unit and ignition switch illumination. Connector & terminal (B280) No. 25 - (B415) No. 6:	Is harness normal?	Go to step 6 .	Check the harness for open circuits and shorts between the body integrated unit and ignition switch illumination.
6 CHECK IGNITION SWITCH ILLUMINATION BULB . Apply battery voltage between terminals of the bulb. Terminals No. 2 (+) - No. 6 (-):	Does the bulb illuminate?	Replace the body integrated unit. Ref. to BODY INTEGRATED UNIT .	Replace the immobilizer antenna. Ref. to REMOVAL , Immobilizer Antenna.
