Before Replacement

WARNING: This page is about a different car, the 2018 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

When replacing BCM, save or print current vehicle specification with CONSULT configuration before replacement. Refer to Work Procedure .

CAUTION: When replacing the BCM, a new BCM must be used. The functions controlled by the BCM do not operate properly if a BCM from another vehicle is used.
NOTE: If "Before Replace ECU" cannot be used, use the "After Replace ECU" or "Manual Configuration" after replacing BCM.
