Inspection

•	Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Power Circuit Inspection

1.	Disconnect the Inhibitor swtich connector.

2.	Ignition KEY "ON"" & Engine "OFF".

Measure voltge between supplied power and ground at inhibitor circuit.

Specification : Approx. 12V

Signal Circuit Inspection

1.	Connect the Inhibitor switch connector.

2.	Ignition KEY "ON" & Engine "OFF".

Measure voltages between each terminal and chassis ground during shift lever changed "P, R, N, D".

Specification : See below "Signal Code Table"

Signal Code Table

	P	P-R	R	R-N	N	N-D	D
Signal "1"	12V	12V	0	0	0	0	0
Signal "2"	0	12V	12V	12V	0	0	0
Signal "3"	0	0	0	12V	12V	12V	0
Signal "4"	0	0	0	0	0	12V	12V

Removal

1.	Place the shift lever into the "N" position.

2.	Remove the air cleaner assembly. (Refer to Engine Mechanical System - "Air cleaner")

3.	Remove the battery and the battery tray. (Refer to Engine Electrical System - "Battery")

4.	Disconnect the inhibitor switch connector (A).

5.	Remove the shift cable mounting nut (A).

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

7.	Remove the inhibitor switch (A) after removing the bolts (2ea).

Installation

1.	Check that the shift lever is placed in the "N" position

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 (B) so that necessary adjustments can be made.

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

Tighten the nut (A) and bolts (B) with the specified torque.

Tightening torque

A : 17.7~24.5 N.m (1.8~ 2.5 kgf.m, 13.0 ~ 18.1 lb-ft)

B : 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

6.	Remove the SST (09480-A3800) from the hole.

7.	Connect the inhibitor switch connector (A).

Install the shift cable by tightening nut (A).

Lightly tighten the shift cable mounting nut (A) so that necessary adjustments can be made.

Push the shift cable to the arrow "F" to eliminate free play and then tighten the nut (A) with the specified torque.

Tightening torque:

8.8 ~ 13.7 N.m (0.9 ~ 1.4 kgf.m, 6.5 ~ 10.1 lb-ft)

10.	Install the battery and battery tray. (Refer to Engine Electrical System - "Battery")

11.	Install the air cleaner assembly. (Refer to Engine Mechanical System - "Air cleaner")
