Restore Full Electronic Functionality to Your 2010 GMC Yukon
Are you battling frustrating and unpredictable electrical problems in your 2010 GMC Yukon? Issues like flickering lights, malfunctioning power windows, a dead instrument cluster, or a security system that acts on its own are often traced back to a single, critical component: the Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing and annoying symptoms. This replacement Body Control Module, part number 20839063, is the definitive solution to restore your truck’s systems to perfect working order.
Unlike a standard replacement part that requires a trip to the dealership for expensive programming, this module is delivered to you ready for installation. We use your vehicle’s unique Vehicle Identification Number (VIN) to program the BCM with the latest GM factory software and calibrations before it ships. This ensures seamless integration with your Yukon’s existing systems, making the repair process faster, simpler, and more affordable.
Is Your 2010 Yukon Body Control Module Failing?
A faulty BCM can be difficult to diagnose because its symptoms can mimic other problems. If you’re experiencing any of the following issues, a failing BCM is the likely culprit:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or dashboard lights flickering, staying on, or not turning on.
- ✔ The anti-theft or security system preventing the engine from starting (PassLock issues).
- ✔ Instrument panel gauges (speedometer, tachometer, fuel gauge) behaving erratically or going dead.
- ✔ HVAC controls for air conditioning or heat not responding correctly.
- ✔ Headlights, taillights, or turn signals malfunctioning despite good bulbs and fuses.
- ✔ A persistent battery drain that leaves you with a dead battery overnight (parasitic draw).
From the Diagnostic Bay
We had a 2010 Yukon XL in the shop that was causing its owner endless headaches. The battery would be dead every other morning, and the radio would randomly turn on and off while driving. The owner had already replaced the battery twice and the alternator once with no success. After hooking up our diagnostic tools, we noticed that several network modules weren’t ‘going to sleep’ after the key was turned off. The source of this network chatter was a faulty BCM. It was creating a parasitic draw that drained the battery. By installing a VIN-programmed 2010 Yukon Body Control Module, we solved the battery drain and the erratic radio behavior in one go. It’s a perfect example of how this single component can be the root of multiple, seemingly unrelated electrical issues.
The Plug-and-Play Advantage: VIN Programming Included
The biggest hurdle in replacing a modern vehicle computer is the programming. This BCM eliminates that obstacle. The process is simple:
- Place Your Order: Complete your purchase for the BCM.
- Provide Your VIN: Reply to your order confirmation email with your 17-digit VIN.
- We Program It: Our technicians will flash the module with the specific GM software for your vehicle’s configuration.
- Install and Drive: Once you receive the part, you can install it directly. In most cases, it’s a true plug-and-play repair.
Important Post-Installation Notes
While our programming handles the majority of the setup, some vehicle systems may require a relearn procedure after installation. These are simple sync functions that a qualified technician can perform with a professional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure will be necessary to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light operation and to prevent issues with the traction control system.

Frequently Asked Questions
What does the Body Control Module (BCM) do on my 2010 Yukon?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and the instrument cluster, ensuring all these comfort and convenience features work together properly.
Is this BCM ready to install right out of the box?
Yes, it is. We pre-program the module using your vehicle’s VIN before shipping. This ensures it has the correct software for your specific options and allows for a plug-and-play installation without needing a trip to the dealer for programming.
How do I provide my VIN after ordering?
After you complete your purchase, you will receive an order confirmation email. Simply reply to that email with your 17-digit VIN, and our team will handle the rest. We cannot program or ship the part without your VIN.
What happens if I don’t perform the post-installation procedures?
If required for your vehicle, skipping these procedures can lead to persistent warning lights or system malfunctions. For example, not syncing the airbag system will leave the airbag warning light on. Not performing the brake pedal relearn could affect brake light or traction control functionality.
My original part number isn’t 20839063, but it’s in your list. Will this part work?
Absolutely. Part number 20839063 is a hardware version that supersedes many older part numbers. As long as your original part number is on our compatibility list, this module is the correct, updated replacement for your vehicle.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module, which can be helpful for reference or if you ever decide to revert to the original part for any reason.
