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".
3.
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".
3.
Measure voltages between each terminal and chassis ground during shift lever changed "P, R, N, D".

2.
Remove the air duct.
3.
Remove the battery and the battery tray.
4.
Disconnect the inhibitor switch connector (A).
5.
Remove the shift cable mounting nut (B).
Tightening torque: 7.8~11.8 N.m (0.8~ 1.2 kgf.m, 5.8 ~ 8.7 lb-ft)

6.
Remove the manual control lever (B) and the washer after removing a nut (A).
Tightening torque: 17.7~24.5 N.m (1.8~ 2.5 kgf.m, 13.0 ~ 18.1 lb-ft)

Use a SST (09480-A3800) or 0.1969in.( 5mm) bolt, fix the inhibitor manual control lever in the N jig hole (A) when you assemble the inhibitor (B).
7.
Remove the inhibitor assembly (A) after removing the bolts (2ea).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

When installing, tighten the inhibitor assembly mounting bolt to the specification shown above.

Installation

1.
Install in the reverse order of removal.
