Precaution for Working Range at a Regular Dealership

INFOID:0000000009190094

CAUTION:

The service items unmentioned on this manual are recommended to be performed by a GT-R certified
NISSAN dealer. Because those service items require special equipment and a GT-R certified technical
staff who completed special training.

Aluminum Die-Casting Parts Handling

INFOID:0000000009162082

PROHIBITION OF WELDING OR BEATING REPAIR

• Material made of aluminum die-casting parts is heat-treated and looses strength when being exposed to

welding heat. Do not perform welding repair for cracks, damage or others.

• For aluminum die-casting parts deformation, do not perform repair by beating. Always repair by replacement

as an assembly.

CRACK CHECK

When the vehicle is damaged, always perform a visual deformation check and a crack check.

Crack Check Procedures

For a crack check, use dye penetrant inspection fluid (pre-cleaning fluid, penetrant fluid and developer fluid).

CAUTION:

Always perform a crack check in accordance with the procedures specified by the manufacturer of the
dye penetrant inspection fluid.
1.

Spray pre-cleaning fluid on the checking surface for cleaning.

Spray penetrant fluid on the checking surface and wait until the penetrant fluid soaks into any cracks.

Wipe off excessive penetrant fluid, and then also lightly wipe off penetrant fluid using a wet cloth.

Spray developer fluid on the checking surface.

Cracks, if any, are dyed red in color.

STRAY CURRENT CORROSION

• Corrosion occurs to aluminum die-casting parts by the stray current corrosion phenomenon, when directly

contacting other parts made of steel. Always apply anti-stray current corrosion paint (primer) on the mount-
ing surface.

• Clean mounting surface to prevent any foreign matter, steel powder or others from being mixed in. Always

apply the specified adhesive when installing.

• Corrosion by stray current corrosion may occur when installing with any other bolts than the specified bolt.

Always use the specified bolt that is surface treated.

• When loosening the specified bolt that is tightened, the treated surface may peel. Never reuse the specified

bolt that is tightened once.

TIGHTENING TORQUE CONTROL

Material made of aluminum die-casting parts is soft in term of hardness. Tightening torque must be controlled
exactly as specified. Always use a torque wrench to install any part to the specified tightening torque.

WARNING:

Never use a power tool to remove or tighten bolts for aluminum die-casting part to prevent damage to
aluminum die-casting parts.

Precautions Necessary for Steering Wheel Rotation After Battery Disconnection

INFOID:0000000009162083

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Before removing and installing any control units, first turn the ignition switch to the LOCK position,

then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect

both battery cables.

Revision: 2012 November

2014 GT-R

DLN-20

< PRECAUTION >

[FRONT FINAL DRIVE: F160A]

PRECAUTIONS

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

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

For vehicle with steering lock unit, if the battery is disconnected or discharged, the steering wheel will lock and
cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the operation pro-
cedure below before starting the repair operation.

OPERATION PROCEDURE

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

Turn the ignition switch to ACC position.
(At this time, the steering lock will be released.)

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.

Perform the necessary repair operation.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the ignition switch from ACC position to ON position, then to LOCK position. (The steering wheel will lock
when the ignition switch is turned to LOCK position.)

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

General Precautions

INFOID:0000000009162084

CAUTION:

After finishing servicing, check that all the tools and waste are stored in a customary place.
