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.

Testimonial: "ok...i bought the bcm on line (used)...but the gays in the dealer says i have to buy a new one..because the used cannot be to reflashed...or recoded."

  • Philip Armitage Oct 07, 2009

    you can reflash some things, Your radio can be flashed, keyless and sir data link, but you will not clear the airbag codes tho. these will be vin coding that maybe locked, the only way to get it all to work is with brand new one for all the lights to work, options in the vehicle like hatch release may not work in your used BCM, But if the airbag light being on is ok for you then everything else should be able to be flashed and programmed. If you were in Oshawa I have tech II and would be able to program it for you. Good luck

How can I turn off the passenger side airbag in a 2002 Buick Rendezvous? AND, where can I find an owner manual for my vehicle?


No there is no switch to turn airbags on/off and No the sensors cannot be adjusted.
Owners manual can be purchased from a main dealer or auto parts store.

The power door locks, windows, interior lights, and radio all stopped working on my 2002 Rendezvous. One morning my key fob would not unlock the car and so I did it manually and the security light stayed...


What kind of place did the diagnostics ? Auto part stores ? The BCM - body control module . Takes a proessional or factory scan tool to pull codes from this module .
The body control module (BCM) is capable of accomplishing multiple body control functions. Components directly connected to the BCM are controlled by the BCM outputs. The BCM can control its outputs based on input information it obtains from sensors and switches that are directly connected to the BCM, or by receiving information from other vehicle systems connected to the class 2 serial data link. The BCM evaluates this information and controls certain body systems by commanding an output on or off.
The BCM is also capable of commanding other vehicle systems to control functions that are not directly wired to and/or controlled by the BCM. The BCM accomplishes this task by sending specific messages on the class 2 serial data link. The vehicle system capable of performing such function will respond to the BCM message.
The BCM controls/monitors the following functions:
• Audible warnings
• Indicators control
• Interior lighting
• Exterior lighting
• Power/automatic door locks
• Keyless entry
• Content theft deterrent
• Personalization
• Serial Power Modes
• Electrical Power Management

Hooking up a Tech 2 factory scan tool to see if the BCM will communicate would be the first step in diagnosing this problem ,also checking codes an to see if the scan tool can bidirectionally control the lock's window's etc.. I would suggest a buick dealer !
