Additional Service When Replacing Control Unit: Description

WARNING: This page is about a different car, the 2020 Infiniti QX50. 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 by CONSULT is not necessary)

NOTE:
  • 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.
