Precaution Necessary for Steering Wheel Rotation After Battery Disconnect


  • 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-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 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.


  1. Connect both battery cables.

Supply power using jumper cables if battery is discharged.

  1. 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.
  2. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
  3. Perform the necessary repair operation.
  4. 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.)
  5. Perform a self-diagnosis check of all control units using CONSULT-III.
