Take it to the delaership, or stealershiip as I like to call them. You can't reprogeam the BCM without the special scan II tool.

SOURCE: Buick Rendezvous 2002 need codes?

the BCM needs to be programmed to operate the computer. a GM techII is now required to calibrate BCM to airbag, stereo, keyless entry, and control pcm data. This is required to make it all work. a gm service should have it done within an hour or less just call and ask them how much it would be to program new BCM. it might cost @$75 to $125 but it is needed, to allow the BCM to work properly.

SOURCE: I have a 2002 Buick Rendezvous CX with a locked radio.

what you need to do is pull the radio out and write down the serial number then call the dealer for the code. they may charge you 15-25 bucks but that will save you some money

Do bcm need to be reprogramed


Has to be programmed ,yes .
Body Control Module (BCM) Replacement
If the BCM is replaced, the following procedures must be performed in the subsequent order:
• BCM Reprogramming--Refer to Body Control Module (BCM) Programming/RPO Configuration in Computer/Integrating Systems for replacement, setup, and programming.
• Theft Learn--Refer to Programming Theft Deterrent System Components in Theft Deterrent.

A new body control module (BCM) must be programmed with the proper regular production option (RPO) configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the RPO available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
• The battery is fully charged.
• The ignition switch is in the ON position.
• The data link connector (DLC) is accessible.
• All disconnected modules and devices are reconnected before programming.
To setup a new BCM, access the Vehicle Control Systems in Computer/Integrating Systems menu on the scan tool to program the BCM. Select Module Replacement/Setup and follow the instructions on the scan tool.
If the BCM fails to accept the program, perform the following steps:
• Inspect all BCM connections.
• Verify that the scan tool has the latest software version.

What do need to do to a 2001 Chevy Malibu after changing the BCM do I need to reprogram the whole computer or what


You would most certainly have to have the BCM reprogrammed. The dealer (or whomever) will need the VIN number to call up the necessary information to perform the programming.
