Performing the following procedure can automatically activate recommunication of ECM and BCM, but only
when the ECM is replaced with a new one*.
*: New one means an ECM that has never been energized on-board.
(In this step, initialization procedure by CONSULT is not necessary)
NOTE:
• If multiple keys are attached to the key hold er, separate them before beginning work.
• Distinguish keys with unregistered key ID s from those with registered IDs.
