Restore Full Electronic Functionality to Your GM Vehicle
Are you battling strange and frustrating electrical problems in your Chevrolet, GMC, Cadillac, or Buick? Issues like flickering lights, malfunctioning power windows and locks, a faulty security system, or even a vehicle that refuses to start can often be traced back to a single component: the Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing symptoms. This replacement Body Control Module, part number 15880684, is the definitive solution to restore your vehicle’s proper operation.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system acting up, causing alarm or starting issues.
- ✔ The engine cranks but refuses to start due to security system lock-out.
- ✔ Warning lights appearing on the dash for various systems (ABS, Airbag, Traction Control).
- ✔ Unresponsive key fob or remote start features.
Why Choose a Programmed GM Body Control Module?
This isn’t just a part; it’s a complete, ready-to-install solution. The biggest hurdle in replacing a BCM is the need for expensive, dealer-specific programming. We eliminate that step entirely. By providing us with your vehicle’s VIN during checkout, we will flash the module with the latest GM software specific to your exact vehicle configuration. This ensures that when the part arrives, it’s ready for a direct installation, saving you time, money, and the headache of a dealership visit. This Programmed GM Body Control Module is your path to a simple and effective repair.
After installation, some vehicles may require a simple relearn procedure. For example, if the airbag light is on, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a Brake Pedal Position relearn might be necessary. These are standard procedures for this type of repair, and we recommend consulting a service manual or qualified technician if you are unsure.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How do I know if my BCM is the problem?
Common signs include multiple, unrelated electrical issues happening at once. Flickering lights, dead power accessories, and security system faults are classic symptoms. A diagnostic scan by a professional can confirm communication faults with the BCM.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact software and settings your specific vehicle requires. This makes the module plug-and-play and avoids the need for you to have it programmed at a dealership.
Is this part difficult to install?
The physical replacement is typically straightforward, often involving removing a few dash panels to access the module. Since our module comes pre-programmed, the most complex part of the job is already done for you. However, some models may require post-install relearn procedures with a scan tool.
What if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). A professional shop can perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool to resolve this.
Does this part fit my vehicle?
This module fits a wide range of 2006-2013 GM vehicles, including the Impala, Equinox, Tahoe, Savana, Acadia, and more. Please check the extensive fitment list on this page and ensure your original part number is listed. Providing your VIN ensures we program it correctly for your model.
