ECM Re-communicating Function

The 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.

Install ECM.
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.
Maintain ignition switch in ON position for at least 5 seconds.
Turn ignition switch to OFF.
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.
