Before Replacement

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

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.
