Restore Your Cadillac’s Electrical System with a Reliable, Programmed BCM
Are you dealing with baffling electrical problems in your 2010 Escalade EXT? Issues like flickering dashboard lights, power windows and locks operating on their own, or a security system that won’t cooperate are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it malfunctions, it can make your vehicle feel unpredictable and unreliable. Driving a luxury vehicle should be a pleasure, not a source of constant frustration.
This isn’t just a replacement part; it’s a complete solution. We provide a high-quality BCM that is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical cloning service means you can bypass the expensive and time-consuming trip to the dealership for programming. Simply provide your VIN after purchase, and we handle the complex part, delivering a module that’s ready for installation and communication with your truck’s other systems.
From the Diagnostic Bay: The Case of the Ghostly Gremlins
I once had a 2010 Tahoe—which uses a nearly identical electrical platform to the Escalade EXT—come into my shop with the strangest symptoms. The owner said his interior lights would pulse randomly, and the radio would shut off for no reason. He’d been to two other shops that couldn’t find the issue. After checking the grounds and power feeds, I hooked up my professional scan tool and saw multiple ‘Loss of Communication’ codes with the BCM (U-codes). Instead of sending him to the dealer for a new module and a hefty programming bill, we ordered a VIN-programmed 2010 Escalade EXT BCM like this one. The swap took less than an hour, and the ‘ghosts’ were gone for good. This service saves both time and money, turning a complex electronic repair into a manageable job.
Is Your Escalade Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ The security system or keyless entry failing to respond correctly.
- ✔ The instrument cluster displaying incorrect information or warning lights that won’t turn off.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up due to security system confusion.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2010 Escalade EXT, the BCM is typically located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect Connectors: Carefully unplug the multiple wiring harness connectors from the old BCM. They have locking tabs that need to be pressed to release. Do not force them.
- ✔ Remove the Old Module: Unbolt or unclip the original BCM from its mounting bracket.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the wiring harnesses. You should hear a ‘click’ as they lock into place.
Important Post-Installation Information
While our VIN programming handles the majority of the setup, some vehicle systems may require a ‘handshake’ with the new BCM. Depending on your specific model and options, the following procedures may be necessary if you notice a related warning light after installation:
- Airbag System Sync: If the airbag warning light is illuminated, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade diagnostic tool. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: To ensure proper brake light and stability control function, a brake pedal position sensor relearn might be required.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a certified technician for procedures specific to your vehicle.

Frequently Asked Questions
What is a ‘Cloning Service’?
Our cloning service means we program the replacement BCM with your vehicle’s original VIN and specific configuration data. This makes the module ready to install right out of the box, avoiding the need for additional programming by a dealership, which saves you time and money.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check the VIN for accuracy before sending.
Do I need to send my old BCM back?
No, this is not an exchange service and there is no core charge. Your original module is returned to you along with the programmed replacement unit. We do not keep your original part.
Will this fix my ‘Service Airbag’ light?
If the airbag light is on due to a faulty BCM, this part can resolve the issue. However, after installation, the system may need to be synced. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Is this a difficult part for a DIYer to install?
The physical replacement is straightforward for someone with basic mechanical skills. It involves removing a dash panel and swapping the module. The most difficult part—the programming—is already done for you by our team.
Which part number should I match?
This module replaces a long list of interchangeable GM part numbers. As long as your original module’s part number is on our compatibility list, this unit will work for your vehicle once programmed with your VIN.
