Test 3: Door Unlock Detection Switch Circuit

Turn ignition off. Remove wireless door lock ECU from under left side of instrument panel. See Figure. Place all door lock knobs in lock position. Measure voltage (backprobe) between ground and ECU connector terminals No. 6 (Gray/Blue wire), No. 11 (Blue/Black wire) and No. 12 (Blue/Orange wire). See Figure. Battery voltage should exist at each individual reading. If battery voltage does not exist, repair appropriate circuit. If battery voltage exists, proceed to next test given under TROUBLE SHOOTING .
