PRECAUTIONS

Caution

INFOID:0000000003938792

Observe the following precautions when disassembling and servicing drive shaft.
• Perform work in a location which is as dust-free as possible.
• Before disassembling and servicing, clean the outside of parts.
• Prevention of the entry of foreign objects must be taken into account during disassembly of the service loca-

tion.

• Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean cover

must be placed over parts.

• Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adhering

to parts.

• Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by

blowing with air or wiping with paper shop cloths.

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000004448894

NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

 position.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.

OPERATION PROCEDURE

1.

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

2.

Use the Intelligent Key or mechanical key to turn the ignition switch to the 

″

ACC

″

 position. At this time, the

steering lock will be released.

3.

Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.

4.

Perform the necessary repair operation.

5.

When the repair work is completed, return the ignition switch to the 

″

LOCK

″

 position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

6.

Perform a self-diagnosis check of all control units using CONSULT-III.
