WARNING: This page is about a different car, the 2005 Infiniti FX45 and 2005 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.

Performing following procedure can automatically perform re-communication of ECM and BCM or Intelligent Key unit, but only when the ECM has been replaced with a new one (*1).

(In this step, initialization procedure by CONSULT-II is not necessary)

NOTE:
  • When registering new Key IDs or replacing the ECM other than brand new, refer to CONSULT-II Operation Manual NATS-IVIS/NVIS.
  • If multiple keys are attached to the key holder, separate them before work.
  • Distinguish keys with unregistered key ID from those with registered ID.
  1. Install ECM.
  2. Using a registered key (*2), turn ignition switch to "ON".

    *2: To perform this step, use the key that has been used before performing ECM replacement.

  3. Maintain ignition switch in "ON" position for at least 5 seconds.
  4. Turn ignition switch to "OFF".
  5. Start engine.

    If engine can be started, procedure is completed.

    If engine cannot be started, refer to CONSULT-II Operation Manual NATS-IVIS/NVIS and initialize control unit.
