3.

Remove select lever knob.

4.

Remove A/T console finisher.

●

8.

Remove control device assembly.

INSTALLATION

 Note the following, and install in the reverse order of removal.

●

After installation is completed, adjust and check CVT position.

Adjustment of CVT Position

ACS001ZO

1.

Place PNP switch and selector lever in “P” position.

2.

Loosen nut of manual lever.

3.

While pressing manual lever toward front of vehicle (in P posi-
tion direction), tighten nut to specified torque.

Checking of CVT Position

ACS001ZP

1.

Place selector lever in “P” position, and turn ignition switch ON (engine stop).

2.

Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.

3.

Move the selector lever and check for excessive effort, sticking, noise or rattle.

4.

Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transaxle body.

5.

The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.

6.

Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps do not illuminate
when selector lever is in the “P” or “N” position with the lever
pushed against the “R” position.

7.

Confirm the engine can only be started with the selector lever in
the “P” and “N” positions.

8.

Make sure transaxle is locked completely in “P” position.

CVT SHIFT LOCK SYSTEM

Revision; 2004 April

2003 Murano

CVT SHIFT LOCK SYSTEM

PFP:00000

Description

ACS00334

●

The electrical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.

●

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder, respectively.
