Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, locks, interior and exterior lighting, security systems, wipers, and more.
Do I absolutely need to provide my VIN?
Yes. Providing your Vehicle Identification Number (VIN) is essential. We use it to load the correct GM software and settings for your vehicle’s specific options and configuration. This step is what makes the installation process so much simpler and avoids compatibility issues.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is generally straightforward. The BCM is typically located under the dash, either in the center or under the steering column. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. However, if you are not comfortable with this process, we always recommend consulting a qualified technician.
What happens if my airbag light comes on after installation?
In some cases, the new BCM may need to be synchronized with the airbag system (SDM). If the airbag light is on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync that a repair shop can perform.
Does this module fit models other than the Chevy Astro?
Yes. This Programmed 2002-2005 Chevy Astro BCM is also the correct module for a wide range of other GM vehicles from that era, including the GMC Safari, Chevy S10, GMC Sonoma, Chevy Blazer, GMC Jimmy, Silverado, Sierra, Tahoe, Yukon, and more.
