Wipe-After-Wash Mode
When the control sleeve of the right multi-function switch is rotated clockwise to the rear momentary WASH position for more than about one-half second while the rear wiper system is not operating, the SCM sends an electronic washer switch status message to the FCM, then the FCM directs battery current and ground to the washer pump/motor unit and energizes the rear wiper relay control coil. This will cause the washer pump/motor unit to be energized in the rear washer direction and the rear wiper module to be enabled for as long as the switch is held closed (up to about 10 seconds) and to be de-energized when the control sleeve is released. The SCM also provides a hard wired output to the rear wiper module indicating the selected mode and the rear wiper module operates the rear wiper motor at a fixed speed until the control sleeve is released plus two additional wipe cycles before the SCM de-energizes the rear wiper relay and parks the rear wiper blade.
