Expert Insight: The Brains of the Operation
From our 20+ years of experience, we’ve seen how a failing BCM can make even the most luxurious vehicle feel unreliable. Think of the BCM as the vehicle’s central nervous system for comfort and convenience. It manages communication between dozens of switches, sensors, and other modules. When it fails, signals get crossed, leading to the bizarre electrical gremlins you’re seeing. Our VIN-programming service doesn’t just make the part workโit ensures it integrates seamlessly, speaking the correct digital language to your vehicle’s other components right out of the box. This is the key to a successful, lasting repair.
Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require additional electronic ‘handshake’ procedures after the BCM is connected. 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 the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that supervises and controls many of your vehicle’s non-engine-related functions. This includes power windows, power mirrors, air conditioning, power locks, security systems, and interior/exterior lighting.
How does the VIN programming process work?
After you place your order, you provide us with your vehicle’s 17-digit VIN. We use this unique identifier to load the exact software and vehicle-specific settings onto the BCM before we ship it. This makes the unit ready to install without needing a trip to the dealer for programming.
Is this a difficult part to install for a DIY mechanic?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module, which is often located under the dash. However, due to the potential need for post-installation procedures like an airbag sync, we recommend installation for those with advanced DIY experience or by a professional technician.
What happens if I forget to provide my VIN?
Providing your VIN is essential for us to program the module correctly. We cannot ship your order until we receive your VIN, as an un-programmed module will not function in your vehicle. We will contact you to retrieve this information if it is not provided at checkout.
Will this fix my specific electrical problem?
This Programmed GM Body Control Module 20864767 is the correct solution for a wide array of electrical issues. If you are experiencing multiple, seemingly unrelated problems with your vehicle’s lights, locks, or windows, a failing BCM is the most common cause.
