Additional Service When Replacing Control Unit: ECM: Description

WARNING: This page is about a different car, the 2021 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

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 using 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:

When the replaced ECM is not a brand new, the specified procedure (Initialization of Intelligent Key Unit and registration of Intelligent Keys) 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.
