Is your 2010 GMC Yukon or other compatible GM vehicle suffering from bizarre electrical problems? Flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own 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 difficult-to-diagnose issues. This replacement BCM is the definitive solution to restore your vehicle’s functionality and peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures that the BCM communicates correctly with your vehicle’s other electronic systems, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN at checkout, and we’ll handle the rest.
We had a 2010 Yukon come in with a classic ‘ghost’ problem. The owner complained of the interior lights staying on intermittently, draining the battery overnight. We checked the battery, alternator, and for parasitic draws, but everything seemed fine. After swapping a few relays with no luck, we focused on the BCM. Once we installed a new, properly programmed BCM, the phantom light issue vanished completely. A faulty BCM can be the hidden cause of the most confusing electrical issues.
Diagnosing a Faulty 2010 Yukon Body Control Module
A failing BCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing several of the following symptoms simultaneously, the BCM is a likely culprit. This module is a direct replacement for a wide range of part numbers, including 15921352, 25892622, and 20815898, ensuring broad compatibility.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle security system engaging randomly or preventing the car from starting.
- ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) illuminating for no reason.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Wipers or radio turning on and off by themselves.
After installation, some vehicles may require additional procedures. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a Brake Pedal Position relearn might be necessary to ensure proper brake light and traction control operation. These procedures are straightforward for any qualified technician.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety 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?
If you are experiencing multiple, seemingly unrelated electrical issues like the ones listed in the description, it’s a strong indicator of BCM failure. A diagnostic scan by a professional can confirm the issue.
What does ‘programmed to my VIN’ mean?
It means we load the module with the specific software and settings for your exact vehicle using your VIN. This makes the installation process much simpler, as it avoids the need for dealer-level programming tools after you receive the part.
Is this part difficult to install?
The physical replacement is typically straightforward, involving unplugging the old module and plugging in the new one. It’s often located under the dashboard. However, as noted, some vehicles may require a simple relearn procedure with a scan tool for the airbag or brake systems after installation.
Will this fit my vehicle if my original part number is different?
Yes, this module is a direct replacement for a long list of GM part numbers. Please check the comprehensive list in our fitment data to confirm it matches one of the compatible numbers for your vehicle.
