Wiper, Rear

When the Rear Wipe Switch (X221) is pulled to the WIPE position, the Multifunction Unit (MFU) (Z148) applies ground to the Rear Wipe Relay (K183). Battery voltage is then applied to the Rear Wiper Motor (M120) from Fuse F4. If the wiper is turned off, battery voltage is no longer supplied from Fuse F4. To allow the wiper to return to his parked position, the window lift ECU (Z147) supplies terminal 87a of the Rear Wiper Relay (K183) with battery voltage for 30 seconds after the Ignition has been turned off.
