Flick Wipe
WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
When the driver moves the wipers and washers control switch to the single wipe position, the BCM/GWM assembly detects a LIN bus message and energizes the wiper on/off relay in the left EJB. The motor will operate at slow speed until the wipers and washers control switch is released from the flick wipe position. The on/off relay is de-energized, removing the power to the windshield wiper motor.
