Unlock Detection Switch Circuit Test

With ignition off, remove luggage compartment left side panel. Remove wireless door lock ECU to gain access to ECU connector. Place all door lock knobs in lock position (door unlock detection switch off). Using DVOM, backprobe ECU connector and measure voltage between terminals No. 11 (Light Green/Black wire), No. 12 (Yellow wire), No. 13 (Blue/Orange wire) and chassis ground. See Figure. Each terminal voltage reading should be between 10-14 volts. If specified voltage is not detected, repair Light Green/Black wire, Yellow wire and/or Blue/Orange wire.
