Remove wireless door lock ECU (leave wire harness connected). Using DVOM, measure voltage (backprobe) between ground and terminal No. 15 (Blue/White wire) at wireless door lock ECU harness connector. See Figure. If battery voltage is present, perform next inspection listed in symptom diagnosis table. See SYMPTOM DIAGNOSIS . If battery voltage is not present, repair harness and/or connectors between wireless door lock ECU and door key lock/unlock switch. See WIRING DIAGRAMS .
