Restore Full Electrical Function to Your Suburban Instantly
If you’re dealing with bizarre electrical issues in your 2010 Suburban 1500ālike flickering lights, malfunctioning power windows, a security system that acts up, or even a vehicle that won’t startāa failing Body Control Module (BCM) is the likely culprit. As the central command for your truck’s body electronics, when the BCM goes down, it can create a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it’s a matter of reliability and safety. This replacement BCM, part number 20815898, is your direct-fit, hassle-free solution.
We offer a professional cloning service that makes this repair easier than ever. Forget about expensive trips to the dealership and waiting for complex programming. Simply send us your original BCM, and we will transfer all of its vital dataāincluding key programming, mileage, and specific vehicle optionsāto this replacement unit. The module you receive back will be 100% plug-and-play, ready for immediate installation. It arrives with the latest GM software updates, ensuring optimal performance and longevity.
Is Your Suburban Showing These Symptoms?
- ā Erratic or non-working interior/exterior lights
- ā Power windows, locks, or mirrors operating intermittently
- ā The security system light stays on, or the alarm goes off randomly
- ā Instrument cluster gauges behaving strangely or not working at all
- ā Trouble codes related to communication loss, such as U0140, U0155, or other U-codes

- ā The ‘Service Theft Deterrent System’ message appears on the dash
A Technician’s Notebook: The Case of the Haunted SUV
A customer brought in a 2010 Suburban 1500 with a list of complaints that sounded like a poltergeist had taken up residence. The dome lights would flicker while driving, the radio would shut off, and occasionally the driver’s side window wouldn’t respond. They had already replaced the battery and checked the main grounds. After hooking up my scan tool, I saw multiple communication loss codes with various modules. In my 20+ years of experience, this pattern almost always points back to one component: a failing BCM. The internal circuits and relays on these modules can degrade over time from heat and vibration, causing these exact ‘ghost in the machine’ issues. We performed a BCM clone, and the vehicle was back to normal in an afternoonāno more ghosts, just a happy customer.
A Straightforward Guide to Installation
- ā Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ā Locate the BCM: On your 2010 Suburban, the Body Control Module is typically found under the steering column, mounted to the left of the driver’s side dash. You may need to remove a lower dash panel for access.
- ā Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ā Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- ā Reconnect Battery: Reattach the negative battery terminal.
- ā Perform Final Checks: Start the vehicle and test all body functions: lights, locks, windows, radio, and wipers. Check the instrument cluster for any warning lights.
Important Post-Installation Procedures
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation. This also requires a bi-directional scan tool.
Disclaimer: Procedures can vary slightly. Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a ‘cloning service’?
Cloning is a process where we transfer the complete software and vehicle-specific data (like VIN, mileage, and key information) from your original BCM to this replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for any additional programming after installation.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to extract the data. We will perform the service and ship both your original module and the ready-to-install replacement back to you.
Will my current keys and remote fobs work?
Absolutely. Because we clone your original data, the replacement BCM will recognize your existing keys and remotes without any need for reprogramming, saving you time and money.
What if my original BCM is completely dead or won’t communicate?
In many cases, even if the BCM is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by water or fire), please contact us before ordering so we can discuss alternative programming options based on your VIN.
Is this a difficult part for a DIY mechanic to replace?
The physical replacement is straightforward for someone with basic mechanical skills. It’s typically located under the dash and involves removing a trim panel and a few bolts/clips. Our cloning service eliminates the hardest partāthe software programmingāmaking it an accessible DIY job.
