Subject:
Body Control Module (BCM) Related Service, Theft Deterrent Re-Learn Procedure
Models:
2000 Chevrolet Impala, Monte Carlo
This bulletin is being revised to update the service procedure and the labor time information. Please discard Corporate Bulletin Number 99-06-O4-057
(Section 6 - Engine/Propulsion System).
BCM replacement is not complete until the BCM is configured to the vehicle and the vehicle theft deterrent re-learn is completed. Without BCM
configuration, the radio will display locked (Theft Lock Enabled) and the vehicle's engine will not crank (Vehicle Theft Deterrent Enabled). The radio
theft lock system compares the VIN in the BCM with the VIN in the radio. If the VIN was not entered in the BCM at the time of
replacement/configuration, the radio will display "Locked". If the vehicle theft deterrent procedure is not completed properly, the engine will not crank
when the key is turned to the crank position.
Important:
If the module is not properly configured within twenty (20) key cycles (including the VIN), the module will lock and configuring will not be allowed.
For this reason, replacing the module with a module from another vehicle will not work. They cannot be reconfigured.
When replacing the BCM, a critical component of the procedure requires a configuring of the BCM. To configure the BCM, follow all of the steps in the
procedure listed below.
Important:
Before starting this procedure, read through it carefully and completely.
The BCM will not function properly if the "set-up 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.
Configuring of the BCM requires the use of the Tech 2 scan tool.
Ensure that the Tech 2 has been updated.
Begin the service procedure with the original BCM in the vehicle.

2.
Connect the Tech 2 scan tool to the Data Link Connector (DLC).
3.
