Door Unlock Detection Switch Circuit Test

Backprobe for voltage between ground and wireless door lock ECU terminal No. 15 (Blue/White wire). See Figure. Battery voltage should exist with door driver's door lock knob in lock position. Backprobe for voltage between ground and wireless door lock ECU terminal No. 21 (Pink wire). If voltages are as specified, go to next test listed in TROUBLE SHOOTING . If either voltage reading is not as specified, repair open or short in Blue/White wire or Pink wire between wireless door lock ECU and door unlock detection switch (in appropriate door lock motor assembly). Retest system operation.
