Additional Service When Replacing Control Unit: ECM: Description

Performing the following procedure can automatically activate re-communication of ECM and BCM, but only when the ECM is replaced with a new one*. For details, refer to WORK PROCEDURE .

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

(In this step, initialization procedure using 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.
