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.
