      DOWN 0
      3 UP 0
      DOWN Battery voltage

      Is the measurement value within the specification? 

      YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

      NO: Replace main power window and door lock/unlock switch. Refer to "REMOVAL AND INSTALLATION ".

  6. CHECK MAIN POWER WINDOW AND DOOR LOCK/UNLOCK SWITCH OUTPUT SIGNAL (REAR POWER WINDOW SWITCH RH)
    1. Connect main power window and door lock/unlock switch.
    2. Turn ignition switch ON.
    3. Check voltage between main power window and door lock/unlock switch connector and ground.
      Terminal Window switch position (rear RH) Voltage (V) (Approx.)
      (+) (-)
      Main power window and door lock/unlock switch connector Terminal
