ECM Re-Communicating Function: Description

Performing following procedure can automatically perform re-communication of ECM and BCM, but only when the ECM has been replaced with a new one^* .

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

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

NOTE:

When registering new Key IDs or replacing the ECM that is not brand new, the initialization of BCM using CONSULT is necessary.
If multiple keys are attached to the key holder, separate them before beginning work.
Distinguish keys with unregistered key IDs from those with registered IDs.
