* Rear wiper operation

The back door ECU activates the rear wiper in either an intermittent or continuous operation according to rear wiper SW command from the body ECU. At this point, the position of the back door window is confirmed, and if it is not fully closed, the command will be ignored, thereby preventing the rear wiper from activating.

If the ignition SW is turned OFF while the rear wiper is operating, it comes to a stop but only after the wiper arm has returned to its initial position.

* Rear washer operation

Turning the rear washer SW ON while the ignition SW is ON and the back door window is fully closed will activate the rear washer.
