Precaution for Procedure without Cowl Top Cover
INFOID:0000000001117288
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000001117287
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.
Draining Engine Coolant
INFOID:0000000000893910
Drain engine coolant and engine oil when the engine is cooled.
Disconnecting Fuel Piping
INFOID:0000000000893911
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disconnecting and disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
