Frequently Asked Questions
What does a Body Control Module (BCM) do?
The 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, door locks, the security system, interior/exterior lighting, wipers, and the HVAC system.
Why is VIN programming so important for this part?
VIN programming configures the new BCM with your vehicle’s specific options and security information. Without it, the module won’t communicate correctly with other computers in the vehicle, which can lead to features not working, persistent warning lights, or even a no-start condition.
Is this BCM difficult to install?
No, the physical installation is typically very straightforward. The BCM is usually located under the driver’s side dashboard near the steering column. It’s a matter of disconnecting the battery, unplugging the electrical connectors from the old module, removing it, and installing the new one. The entire process often takes less than 15 minutes.
What if my airbag light is still on after installation?
In some cases, particularly if you had an airbag code like B1001, a final sync procedure is needed. This is called ‘Setup SDM Primary Key in BCM’ and must be performed with a professional-grade scan tool. It’s a quick procedure that a local repair shop can easily handle.
Will this module fit my vehicle if my part number is slightly different?
Yes, this BCM is a direct replacement for a wide range of interchangeable part numbers, including 25835966, 15943678, 20939137, 22860591, and many others listed in the compatibility data. Our programming ensures it works correctly for your specific application.
By choosing the right part, like this pre-programmed 25835965 Avalanche 1500 Body Control Module, you ensure a lasting repair that restores your vehicle’s reliability and your confidence behind the wheel.
