2. The BCM will not function properly if the Setup New BCM procedure is not performed.
3. Perform the Programming Theft Deterrent System Components in Theft Deterrent after successfully finishing the Setup New BCM procedure. If the Programming Theft Deterrent System Components procedure is not performed after a BCM replacement, one of the following conditions will occur:

-	The vehicle will not be protected against theft by the PASSLOCK system.

-	The engine will not crank nor start.

Important: After the procedure is completed, the personalization settings of the BCM are set to a default setting. Inform the customer that the personalization must be set again.
