Restore Full Functionality to Your GM Vehicle with a Programmed BCM
Is your 2010 GMC Yukon or other compatible GM vehicle suffering from bizarre electrical issues? As a technician with over 20 years of experience, I’ve seen it all: power windows with a mind of their own, intermittent door lock failures, security lights that won’t turn off, and even frustrating no-start conditions. More often than not, the culprit is a failing Body Control Module (BCM). This isn’t just an inconvenience; it can be a major safety and security concern. This BCM, part number 25826125, is your direct-fit, reliable solution.
A Technician’s Notebook: The Case of the Haunted SUV
I remember a 2010 Yukon that came into my bay last winter. The owner was at his wit’s end. The interior lights would flicker randomly, the radio would shut off, and sometimes the power liftgate wouldn’t open. He’d already replaced the battery and checked the main grounds. After connecting my scan tool, I found a slew of U-codes (communication errors) pointing to the BCM. Instead of a costly and time-consuming replacement at the dealership, we used a cloned BCM. The process was simple: we transferred the data from his original failing module to the replacement. Once installed, every single electrical gremlin vanished. It’s a textbook example of how a failing BCM can wreak havoc, and how the right part makes for a fast, effective repair.
Is Your Vehicle Showing These Symptoms of BCM Failure?
The Body Control Module is the central hub for your vehicle’s comfort and convenience electronics. When it starts to fail, you’ll notice a pattern of strange, unrelated electrical problems. Here are the most common signs I’ve diagnosed in my shop:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ The security or anti-theft light stays on, potentially causing a no-start condition.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The horn sounding unexpectedly or not working when pressed.
- ✔ Dashboard warning lights appearing randomly (e.g., ABS, Airbag, Traction Control).
- ✔ Communication error codes stored in the system, often starting with ‘U’ (e.g., U0140 – Lost Communication With Body Control Module).
A Straightforward Guide to Installation
Our cloning service makes this repair accessible for both seasoned mechanics and dedicated DIYers. By transferring your vehicle’s original data to this replacement module, you bypass the need for expensive dealership programming tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Locate the BCM: On a 2010 Yukon, the BCM is typically located under the driver’s side of the dashboard, near the steering column. Its position varies on other models (see fitment list).
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or clips holding the module in place.
- Install the New BCM: Mount the new, programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, etc.—to confirm the repair was successful. Please review the post-installation procedures below.
Important Post-Installation Information
While our cloning service handles the primary programming, some vehicle systems may require a relearn or synchronization procedure after the BCM is replaced. This is a normal part of the vehicle’s security and safety architecture.
- Airbag System Sync: If your 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 required to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
What is a BCM cloning service?
Our cloning service involves transferring the unique, vehicle-specific software and security data from your original BCM to this replacement unit. This makes the new module plug-and-play, eliminating the need for a trip to the dealership for expensive programming.
How does the process work?
After you place your order, you will need to ship your original BCM to us. We will perform the cloning service and ship both your original module and the newly programmed replacement back to you. You must provide your VIN so we can ensure the latest GM software updates are applied.
Do you keep my old BCM?
No. This is not a core exchange program. Your original module is required only for the data transfer and will be returned to you along with the replacement unit.
Will this fix my exact problem?
This BCM will correct issues directly caused by a faulty module. If you’re experiencing the common symptoms listed above, there is a very high probability this part is the solution. For a definitive diagnosis, we recommend having a professional mechanic check for communication codes.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very manageable job. The main challenge is typically accessing the module under the dashboard. No special tools are required for the physical swap, but a professional scan tool may be needed for post-installation relearn procedures as noted above.
