Door Unlock Sensor Check

  1. Measure voltage by backprobing between appropriate SECU terminals and ground. See DOOR UNLOCK SENSOR CHECK  table. If voltages are not as specified, go to next step. If voltages are as specified door unlock sensor is okay.
  2. Perform door unlock sensor test. See SENSORS  under COMPONENT TESTS. If sensor is okay, inspect unlock sensor ground circuit (Black wire) and/or Orange wire (front passenger door), Yellow/Red wire (front driver door) or Yellow wire (both rear doors) for open or short between SECU and door unlock sensor.
