Additional Service When Replacing Control Unit: ECM: Description

WARNING: This page is about a different car, the 2016 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

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

(In this step, initialization procedure by CONSULT is not necessary)

If multiple keys are attached to the key holder, separate them before beginning work.
