Check ECU-IG Fuse

Remove front lower panel. Remove 15-amp ECU-IG 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 is present, replace ECU. If battery voltage is not present, repair open in Red/Blue wire.
