Adjustment (With Marked Switching Ranges (X, Y & Z)

NOTE: Two adjustment procedures are available dependent on visual inspection. Vehicles with catches marked with switching ranges (X, Y & Z), and vehicles without marked ranges (X, Y & Z). Inspect caches for appropriate procedure. For vehicles without marked ranges, See ADJUSTMENT (WITHOUT MARKED SWITCHING RANGES (X, Y & Z)  .
NOTE: During procedures the numbers in parentheses, within steps, correspond to numbers inside the illustration(s). The word arrow(s) in parentheses, within steps, is used to point out specific components or movement.
  1. With catch locked, press rotating lock (5) in "release" direction 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, Z) by this amount. See Fig 1 .
  2. Release catch. Attach multimeter to plug connector (A24x or A25x, pins 3 and 4). Set multimeter to continuity check (acoustic signal). Press catch in LOCK direction with top wrench (vehicle tool kit). Simultaneously press rotating lock (5) upward with thumb to eliminate play. Limit switch (A24s2 or A25s2) should actuate when the upper edge of the rotating lock (5) is in the switching range (Y). If necessary adjust limit switch (A24s2 or A25s2) by sliding in oblong holes. Apply screw-securing agent to screws (3) for limit switch (A24s2 or A25s2). See Fig 2 .
