Wiper Motor, Deactivating Alternating Park Position (APP) Function, Through 05.09

Special tools, testers and auxiliary items required

• Vehicle Diagnostic Tester

• Diagnostic Cable (VAS 5051/6A)






The windshield wiper system is equipped with the APP function (alternating park position).

The APP function causes the wiper at every second shut off to move upward slightly after reaching the lowest position.

To install the wiper arm on the linkage, the motor must be switched off 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 wiper motors in which the APP function was deactivated as well as for new wiper motors.
