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.
