Pulse Wipe Mode

When the control knob on the control stalk of the multi-function switch is depressed to the momentary pulse wipe position for less than about one-half second, the SCCM sends an electronic switch message to the FCM, then the FCM energizes the wiper on/off relay for one complete wipe cycle. The FCM de-energizes the relay when the state of the park switch sense changes to ground, parking the wiper blades near the base of the windshield.
