ECM Re-communicating Function

WARNING: This page is about a different car, the 2005 Nissan 350Z. 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, but only when the ECM has been replaced with a new one (*1).

*1: New one means a virgin ECM which has never been energized on-board.

(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 (except for card plate 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.
