Test 2: Ignition Switch Circuit

Remove front lower panel. Remove ECU-IG (15-amp) fuse from instrument panel junction block. Check fuse. Replace fuse as necessary. If fuse is okay, disconnect wireless door lock ECU connector. Turn ignition on. Measure voltage (backprobe) between ECU connector terminal No. 13 (Red/Blue wire) and ground. If battery voltage exists, replace ECU. If battery voltage does not exist, repair open in Red/Blue wire.
