Is Your Truck Plagued by Baffling Electrical Issues?
Are you dealing with power windows that won’t cooperate, door locks with a mind of their own, a security light that won’t turn off, or gauges that flicker erratically?

Is This The Right Part For You?
This BCM is a common solution for a variety of Diagnostic Trouble Codes (DTCs), especially U-codes (e.g., U1000, U1016) indicating a loss of communication between modules. If you’re experiencing issues with any of the following, a faulty BCM is the likely cause:
- Power windows, mirrors, or door locks operating intermittently or not at all.
- Interior or exterior lights staying on or not turning on.
- Erratic or non-functional instrument panel gauges.
- Vehicle security system engaging randomly or preventing the engine from starting.
- Radio or climate control malfunctions.
By installing our Programmed 2002 Chevy Avalanche 1500 BCM, you are not just replacing a part; you are restoring your vehicle’s core electronic stability.
Important Post-Installation Information:
While this module is designed for a straightforward installation, some vehicles may require additional steps to sync all systems. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor may be necessary to ensure proper brake light and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What exactly 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, interior and exterior lighting, security systems, wipers, and more. It’s the central hub for your vehicle’s body electronics.
Is this BCM difficult to install?
For someone with basic mechanical skills, the physical replacement is typically straightforward. The BCM is usually located under the dashboard. Since our module comes pre-programmed, the most complex part of the job is already done for you. However, some vehicles may require the post-installation procedures mentioned above.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you to request your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your exact vehicle.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your original module, which saves you the time and expense of return shipping.
What if my airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to your vehicle’s airbag module (SDM). A qualified mechanic with a high-end diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Will this Programmed 2002 Chevy Avalanche 1500 BCM fix my specific problem?
This module is the correct solution for the wide range of symptoms caused by a failing BCM. While it resolves the most common electrical issues, we always recommend confirming your diagnosis with a qualified technician to ensure the BCM is the root cause of your specific problem.
