Connect multimeter to plug connector (A22x or A23x, pins 1 and 2). Set multimeter to continuity test (acousting signal). Press rotating lock (5) in direction "lock" with thumb. Limit switch (A22s1 or A23s1) should actuate when the upper edge of the rotating lock (5) is in switching range (Z). If necessary adjust limit switch (A22s1 or A23s1) by moving in oblong holes. Apply screw-securing agent to screws (3) for limit switch (A22s1 or A23s1).







Lock catch. Press rotating lock (5) in direction "release" with thumb until resistance is felt. The rotating lock (5) should form a line with mark X (main catch). If not adjust switching range (Y) by this amount.

Press catch in direction "lock" with top wrench (vehicle tool kit). Simultaneously press rotating lock (5) upward with thumb to eliminate play. Limit switch (A22s2 or A23s2) should actuate when the upper edge of the rotating lock (5) is in the switching range (Y). If necessary adjust limit switch (A22s2 or A23s2) by sliding in oblong holes. Apply screw-securing agent to screws (3) for limit switch (A22s2orA23s2).
