Restore Your Vehicle’s Brain and Banish Electrical Gremlins
Is your 2010 Chevrolet Tahoe or other GM vehicle acting possessed? Flickering lights, intermittent power windows, door locks with a mind of their own, or a security system that prevents your truck from starting are all classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an annoyance; it’s a breakdown in your vehicle’s core communication system.
This replacement Body Control Module, part number 15921352, is the definitive solution. We eliminate the biggest hurdle in BCM replacement: the expensive and time-consuming trip to the dealership. With our professional Cloning Service, we transfer the critical data from your original, failing module directly onto this replacement unit. This ensures that your vehicle’s specific options, key information, and security settings are perfectly preserved, making installation remarkably straightforward.
A Technician’s Notebook: The Case of the Erratic Escalade
I remember a 2010 Escalade that came into the shop with a laundry list of bizarre symptoms. The radio would turn on and off, the driver’s side power window wouldn’t work, and occasionally the vehicle wouldn’t start, flashing a ‘Service Theft Deterrent System’ message. The customer had already replaced the battery and checked fuses. After hooking up the scan tool, I saw multiple ‘U’ codes, indicating a loss of communication between various modules. This immediately pointed me to the BCM. Instead of sending the customer to a dealer for a new, unprogrammed module, we used a cloned unit. We transferred the data from his old BCM to the new one. Within an hour of the part arriving, the module was swapped, and every single electrical gremlin was gone. This cloning process saved the customer hundreds of dollars and a full day of vehicle downtime.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Erratic instrument cluster behavior or warning lights that come and go.
- ✔ Communication error codes, such as U0100, U0140, or other U-series DTCs.
- ✔ The horn honks randomly or the alarm goes off without reason.
- ✔ Remote keyless entry (RKE) stops working reliably.
Your Straightforward BCM Installation Guide
Thanks to our cloning service, installing your replacement 2010 Tahoe BCM is a job most DIYers can handle. Here’s a general guide:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most compatible trucks and SUVs like the 2010 Tahoe, the BCM is located under the driver’s side of the dashboard, often near the steering column. For vans and other models, it may be in the center dash area.
- Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM into the mounting bracket and secure it. Reconnect all electrical connectors firmly until they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions: power windows, locks, interior/exterior lights, radio, and wipers to confirm the fix.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play process, some GM vehicles are sensitive. Please be aware of these potential, but not always required, procedures:
- Airbag System Sync: If the airbag warning light is illuminated 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 relearn may be required to ensure proper brake light and traction control operation.
- Core Return: We make it simple. Your original module is always returned to you along with your newly programmed replacement unit. We do not keep your core.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified professional if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we transfer the essential vehicle-specific data—like your VIN, key information, and optional features—from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for dealer programming.
Do I need to take my vehicle to a dealer after installation?
No. Our cloning service is designed to make this a ready-to-install part. In most cases, no further programming is required, saving you significant time and money.
Where is the BCM located on my 2010 Tahoe?
On the 2010 Chevrolet Tahoe, the Body Control Module is typically found under the driver-side dashboard, attached to a bracket near the steering column.
What happens to my original BCM?
Your original module is required for the cloning process and will be returned to you along with the newly programmed replacement unit. We do not keep customer cores.
Will this fix my ‘Service Airbag’ light?
A faulty BCM can cause a false airbag light. If the light remains on after installing the cloned BCM, it may simply need to be synchronized using the ‘Setup SDM Primary Key in BCM’ procedure, which requires a professional scan tool.
After I purchase, how do I provide my information for programming?
After you complete your purchase, we will provide clear instructions for sending in your original module for the cloning service. We will also use your VIN to ensure the replacement module has the latest GM software updates loaded before cloning.
