PRECAUTIONS PFP:00001
Precautions Necessary for Steering Wheel Rotation After Battery Disconnect
ABS00DAO
NOTE:
● This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
● Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
● Always use CONSULT-II 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 NVIS/IVIS, an electrically controlled steering lock
mechanism 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-II.
Precautions for Drain Engine Coolant ABS006HV
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel Piping ABS006HW
● 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.
Precautions for Removal and Disassembly ABS006HX
● When instructed to use special service tools, use specified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
● Exercise maximum care to avoid damage to mating or sliding surfaces.
● Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
● Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
● When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be
used where noted in the step.
Precautions for Inspection, Repair and Replacement ABS006HY
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and Installation ABS006HZ
● Use torque wrench to tighten bolts or nuts to specification.
