Wiper Arm: Testing and Inspection

AR82.30-P-6000-01GZ Check Wiper Arms

Modification Notes:

Wiper Arm Test And Adjustment Values:

Special Tools:

Component Identification:

1.1 If the wiper arms are not in the reversing position: Switch on ignition, set wiper switch to position "2". When the wiper arms are close to the reversing position, switch ignition off again, set wiper switch to position "0". Remove ignition key from EIS [EZS] control unit.

On vehicles with Keyless Go, code 889: Press start/stop button repeatedly until the ignition is switched off. Remove transmitter key from vehicle and store it in a location beyond its transmission range (at least 2 m).

1.2 If the wiper arms are not precisely in the reversing position: Manually move driver-side wiper arm (1) and passenger-side wiper arm (2) into the reversing position.

The wiper arms are in the upper reversing position, if
^ the distance between the upper end of the driver-side wiper blade (3) and the rubber seal of the driver-side A- pillar (dimension D) is approx. 30 mm,
^ the distance between the upper end of the passenger- side wiper blade (4) and the rubber seal of the driverside A-pillar (dimension E) is approx. 460 mm,

2 Insert adapter "E" into the guide of the angle gauge (5) and fasten with knurled bolt (6a) to angle gauge (5).
3 Fold up driver-side wiper arm (1), remove driver-side wiper blade (3).
4 Slide adapter "E" together with the angle gauge (5) onto the wiper blade mount of the driver-side wiper arm (1) and clamp tight with the knurled bolt (6b).
5 Carefully lower driver-side wiper arm (1) onto windshield. All three contact points at the foot of angle gauge (5) must touch the windshield.
6 Read off angle of incidence of driver-side wiper arm (1) in the reversing position on the scale of the angle gauge (5), record and compare to the corresponding specified value.
7 Lift driver-side wiper arm (1), loosen knurled screw (6b), remove adapter "E" together with the angle gauge (5) from driver-side wiper arm (1).
8 Attach driver-side wiper blade (3), carefully fold driver-side wiper arm (1) onto windshield.
9 Repeat test procedures 3 to 8 on passenger-side wiper arm (2) in reversing position.
10 Switch on ignition, turn wiper switch to position "0". When the wiper arms are in parked position, switch off ignition again and remove transmitter key from EIS [EZS] control unit.

On vehicles with Keyless Go, code 889: Press Keyless Go start/stop button repeatedly until ignition is switched off. Remove transmitter key from vehicle and store it in a location beyond its transmission range (at least 2 m).

11 Repeat test procedures 3 to 8 on driver-side wiper arm (1) and on passenger-side wiper arm (2) in parked position.
