Restore Full Functionality to Your Vehicle’s Electronics
Are you battling bizarre electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows, a dead radio, or random warning indicators on your dash are common signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable issues. This replacement module is the definitive solution to restore your vehicle’s systems to perfect working order.
From the Diagnostic Bay
We had a 2010 Chevy Tahoe come in with the strangest symptoms. The owner said the dome lights would flicker randomly, the driver’s side power window would only work intermittently, and the security light would stay on for minutes after starting the truck. He had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we found multiple communication errors pointing back to the BCM. Instead of a complex and costly wiring chase, we installed a VIN-programmed 2010 Avalanche Body Control Module (the same part fits the Tahoe), and every single electrical gremlin vanished. It’s a reminder that one central component can be the root of many seemingly unrelated problems.
Is Your BCM Failing? Common Symptoms:
- ✔ Erratic or non-functional power windows, locks, and mirrors.
- ✔ Interior or exterior lights that don’t work correctly or stay on.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Horn, wipers, or radio functioning intermittently or not at all.
- ✔ False warning lights on the instrument cluster (e.g., ABS, Airbag, Traction Control).
- ✔ A/C and climate control system malfunctions.
The Simple, Dealer-Free Solution
Don’t waste time and money at the dealership. We make the replacement process simple. This BCM comes fully programmed with the latest GM software specifically for your vehicle. All you need to do is provide us with your Vehicle Identification Number (VIN) during checkout. We handle the complex programming, so you receive a part that is ready for installation right out of the box. This service ensures compatibility and saves you from needing expensive dealer-only scan tools for setup.
Post-Installation Information
While this 2010 Avalanche Body Control Module is designed for a straightforward installation, some vehicles may require minor post-installation procedures. In some cases, if the airbag warning light appears, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. Additionally, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and stability control function. These are standard procedures that can be performed by any qualified technician with a professional-grade diagnostic tool. There is absolutely no core charge, so you can keep your old part.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body and cabin electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the radio.
Is this BCM really plug-and-play?
Yes, for most functions. We program it to your vehicle’s VIN before shipping, which handles the most critical setup step. Some vehicles may require a simple relearn procedure for the brake pedal sensor or airbag system after installation, as noted in the description.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information to ensure it is programmed correctly for your specific vehicle.
What if my airbag light is on after I install the BCM?
This can happen on some models. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep or dispose of your original module.
