INFORMATION
Subject:
Body Control Module (BCM) Related Service, Theft Deterrent Re-Learn Procedure
Models:
2000 Chevrolet Impala, Monte Carlo
BCM replacement requires that a programming function be performed. If the BCM is not properly programmed, the vehicle may not start because the
Theft Lock System will be enabled.
Important:
If the module is not properly programmed within twenty (20) key cycles (including the VIN), the module will lock and programming will not be
allowed. For this reason, replacing the module with a module from another vehicle will not work. They cannot be reprogrammed.
When replacing the BCM, a critical component of the procedure requires a programming of the BCM. To program the BCM, follow all of the steps in
the procedure listed.
Important:
Before starting this procedure, read through it carefully and completely.
The BCM will not function properly if the "setup new" BCM procedure is not performed correctly.
Also, perform the theft deterrent re-learn procedure. If this is not performed, the following conditions will occur:
-
The vehicle will not be protected against theft by the Passlock(TM) system.
-
The engine will not crank or start.
Programming of the BCM requires the use of the Tech 2 scan tool.
1.
Insure that the key (or ignition) switch is in the LOCK position with the ignition off.
2.
Connect the Tech 2 scan tool to the Data Link Connector (DLC).
3.
Turn the key to the ON position.
4.
The following items all refer to the Tech 2 scan tool inputs:
^
Select Diagnostics and answer the questions when prompted by the Tech 2.
^
Select Body Control Module (BCM).
^
Select Special Functions.

Select New VIN and input the required data.
^
Exit back to the Special Functions menu.
5.
Select BCM Programming.
6.
Press the YES key when the following message is displayed: Do you want to setup a body control module?
7.
The Tech 2 will then display the following message: Now setting up the New Body Control Module.

When the BCM has been setup successfully, the Tech 2 will display this message: Body Control Module setup is complete.
