3.	Disconnect the inhibitor switch connector (A) and loosen the shift cable mounting nut (B).

4.	Remove the manual control lever (B) and the washer after removing a nut (A).

5.	Remove the inhibitor switch (A) after loosening the bolts.

Installation

1.	Check that the gear is shifted to "N".

Install the inhibitor switch (A).

Lightly tighten the inhibitor switch mounting bolts so that necessary adjustments can be made.

Install the manual control lever (A).

Lightly tighten the manual control lever nut so that necessary adjustments can be made.

4.	Align the hole (B) in the manual control lever with the "N" position hole (A) of the inhibitor switch and then insert the SST inhibitor switch guide pin (09480-A3800).

Tighten the manual control lever mounting nut (A).

Tightening torque :

17.7 - 24.5 N·m (1.8 - 2.5 kgf·m, 13.0 - 18.1 lb·ft)

Tighten the inhibitor switch mounting bolts (A).

Tightening torque :

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)

7.	Remove the SST (09480-A3800) from the adjusment hole.

8.	Connect the inhibitor switch connector (A).

Tighten the nut (A) to the specified torque after removing free play by pushing the shift cable in the direction of the arrow.

Tightening torque :

9.8 - 14.7 N·m (1.0 - 1.5 kgf·m, 7.2 - 10.8 lb·ft)
