The test of the wiper arm angle of incidence for the rear-end door in the reversing and park position determines whether the rear-end door wiper arm needs to be adjusted.

Insert adapter (C) into the guide (arrow) of the angle gauge (A) and fasten with knurled bolt to angle gauge (A).
Use adapter (C) and angle gauge (A) from the adjustment tool set.
