As a technician, I’ve seen countless owners spend hundreds on diagnostics, chasing individual symptoms like a faulty window switch or a bad relay, only to discover the BCM was the real culprit. A failing BCM creates a domino effect. The real value here isn’t just the part itself; it’s the pre-programming service. In the past, this was a ‘dealership only’ repair requiring a tow and significant labor charges.

Itโs the most efficient and reliable way to restore your truck’s complex electronic systems.
Installation & Post-Install Notes
While this BCM is designed for a plug-and-play installation, some vehicles may require a simple relearn procedure for specific systems after the new module is installed. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.

Frequently Asked Questions
Do I need to provide my VIN number?
Yes. Providing your VIN during checkout is mandatory. We use it to program the BCM with the correct software and calibrations for your specific vehicle, which ensures a successful plug-and-play installation.
What does a Body Control Module actually do?
The BCM is a computer that supervises and controls many of your vehicle’s non-engine-related functions. This includes power windows, power locks, interior and exterior lighting, security systems, wipers, and various other comfort and convenience features.
Is this a truly plug-and-play installation?
For most vehicles, yes. Because we pre-program the module, you can typically install it and have your vehicle’s functions restored immediately. However, as noted above, some vehicles may require an additional relearn procedure for the airbag or brake pedal position systems using a professional scan tool.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A qualified technician with a high-end diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How do I know if the BCM is really my problem?
While this part fixes the most common causes of BCM failure, we always recommend proper diagnosis. If you have multiple, unrelated electrical issues (e.g., power locks, interior lights, and wipers all acting up), the BCM is a very likely culprit. This programmed 2010 Avalanche 1500 Body Control Module is the definitive solution for a failed unit.
