Wiper Motor Control Module, Deactivating Alternating Park Position Function
The windshield wiper system is equipped with the Alternating Park Position function (APP).
The APP function causes the wiper at every second shut off to move upward slightly after reaching the lowest position.
To install the motor crank on the Windshield Wiper Motor -V-, it is necessary to shut off the windshield wiper motor in the lower park position. This is attained by deactivating the APP function (code Wiper Motor Control Module -J400-).
An activation of APP function is not possible.
APP function is automatically activated after 100 wiping cycles. This applies to windshield wiper motor in which the APP function was deactivated as well as a new windshield wiper motor.
