Rear Wiper and Washer

System Outline

- Rear wiper operation
The back door ECU initiates rear wiper 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 neglected preventing the rear wiper from starting.
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, with the ignition SW ON and the back door window fully closed, initiates rear washer operation.
