Restore Your Cadillac’s Electrical Systems with a Reliable, Programmed BCM
Are you battling frustrating electrical gremlins in your 2010 Cadillac Escalade ESV? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and convenience features, a faulty BCM can make driving your luxury SUV a nightmare. I’ve seen it countless times in my 20+ years in the shop—what seems like a dozen different problems is often just one single component failure.
This is your direct-fit, hassle-free solution. We offer a genuine GM Body Control Module, part number 25910474, that arrives at your door fully programmed to your vehicle’s specific VIN. Simply provide us with your VIN at checkout, and our technicians will flash the module with the latest GM software updates. This means you can skip the expensive trip to the dealership for programming. It’s the most efficient way to get your Escalade’s electronics working perfectly again.
A Technician’s Notebook: The Intermittent Escalade Mystery
A customer brought in a 2010 Escalade ESV with a list of bizarre, intermittent issues: the radio would cut out, the driver’s side power window would stop working, and the instrument cluster would occasionally flash random warnings. They’d been to two other shops that couldn’t pinpoint the problem. After connecting my scan tool, I noticed several ‘Loss of Communication’ codes (U-codes) pointing to the BCM. A failing 2010 Escalade ESV Body Control Module can disrupt the entire data network, causing these seemingly unrelated symptoms. We installed one of our pre-programmed modules, and within an hour, every single issue was resolved. The customer was thrilled to have their reliable, fully functional vehicle back without a prolonged diagnostic headache.
Is Your Escalade Showing These BCM Failure Signs?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system engaging randomly or the key fob not responding.
- ✔ Incorrect readings on the instrument panel gauges or warning lights that won’t turn off.
- ✔ Radio or infotainment system malfunctions.
- ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140.
- ✔ Problems with the HVAC (heating and air conditioning) controls.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2010 Escalade ESV, the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Perform Relearns: Start the vehicle. If the airbag light is on or you notice brake system warnings, proceed with the necessary post-installation procedures outlined below.
Important Post-Installation Information
While this module is programmed for your vehicle, some integrated systems may require a relearn procedure to sync properly. These are standard steps for this type of repair.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync 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 your brake lights and stability control systems function correctly.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified professional if you are unsure about any step.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s VIN during checkout, and it will arrive ready for installation.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures typically require a bi-directional, professional-grade diagnostic scan tool. Many local repair shops can perform these services for you if needed.
Is this difficult to install for a DIYer?
The physical replacement is straightforward for someone with basic mechanical skills, as the BCM is usually in an accessible location under the dash. The main consideration is the potential need for post-install relearn procedures.
How do I find my original part number?
Your original part number is printed on a sticker on the BCM itself. However, since this part fits a wide range of numbers and is programmed to your VIN, matching the part number is less critical than ensuring your vehicle model is on the compatibility list.
