Additional Service When Replacing Control Unit: Description

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)

CAUTION: When replacing the ECM, a new ECM must be used. The functions controlled by the ECM do not operate properly if a ECM from another vehicle is used.

NOTE:

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.
