Additional Service When Replacing Control Unit: ECM: Description

WARNING: This page is about a different car, the 2017 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.

Performing the following procedure can automatically activate re-communication 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.

NOTE:
  • When the replaced ESM is not a brand new, the specified procedure (Initialization of BCM and registration of ignition 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.
