Restore Full Command of Your Cadillac’s Electronics
Are you battling frustrating electrical gremlins in your 2010 Escalade EXT? Intermittent power windows, flickering dash lights, a faulty security system, or even a no-start condition can all point to one culprit: a failing Body Control Module (BCM). As a technician with over 20 years of experience, I’ve seen how a faulty BCM can turn a luxury vehicle into a source of daily headaches. This isn’t just an inconvenience; it’s a breakdown in your vehicle’s central nervous system.
This replacement Body Control Module is the definitive solution. We take the guesswork and dealership hassle out of the equation. Before we ship it, we program the module with the latest GM software updates, specifically matched to your vehicle’s VIN. This ensures seamless integration and restores your truck’s functions to factory specifications. You get a reliable part that’s ready to install right out of the box, saving you from expensive towing and programming fees at a service center.
A Technician’s Notebook
Just last month, a 2010 Yukon—which shares the same platform as the Escalade—was towed into my bay. The owner was at his wit’s end. The radio would turn on by itself, the door locks would cycle randomly while driving, and the security light was constantly on. He had already replaced the battery, thinking it was a simple voltage issue. After connecting my scan tool, I found a flurry of communication errors, specifically a U0140 code (Lost Communication With Body Control Module). A quick inspection under the dash revealed the problem: the BCM had clear signs of corrosion on the connectors, likely from a minor windshield leak over time. We replaced it with one of our pre-programmed modules, and within an hour, every single electrical issue was resolved. It’s a common failure, but one with a straightforward fix.
Is Your Escalade Showing These Signs of BCM Failure?
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ The security system light is illuminated, or the alarm goes off randomly.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The vehicle won’t start, and you hear a rapid clicking sound from the dash.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or B1001.
- ✔ Wipers behaving unpredictably or not parking in the correct position.
Your Straightforward Installation Roadmap
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On your 2010 Escalade EXT, the Body Control Module 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 and Remove: Carefully unplug all 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. Securely reconnect all electrical connectors, ensuring they click into place.
- Power Up: Reconnect the negative battery terminal. Turn the ignition to the ‘ON’ position (without starting the engine) and verify that your electronics are responding.
- Crucial Final Steps: Follow the post-installation procedures below to ensure safety and full functionality.
Important Post-Installation Procedures
After installing your new 2010 Escalade EXT Body Control Module, completing these final steps is critical for safety and proper operation. Failure to do so may result in warning lights and compromised system performance.
- Airbag System Reset: The airbag warning light will likely be on. You must perform the ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade diagnostic scan tool. This re-establishes communication between the new BCM and the airbag system.
- Brake Pedal Position Sensor Relearn: Some vehicles require the Brake Pedal Position Sensor to be recalibrated after a BCM replacement. This ensures the brake lights and stability control system function correctly. This also requires a capable scan tool.
If you are not equipped to perform these procedures, we strongly advise seeking assistance from a qualified professional mechanic.

Frequently Asked Questions
Do I need to program this BCM?
No. This is the biggest benefit of our service. You provide us with your vehicle’s VIN during checkout, and we program the module for you before shipping. It arrives ready for installation.
Where is the BCM located on my 2010 Escalade EXT?
The Body Control Module is located under the driver’s side dashboard, attached near the steering column. You will likely need to remove the plastic knee bolster panel to access it.
What happens if I don’t perform the airbag and brake relearn procedures?
Your airbag warning light will remain on, and the supplemental restraint system (SRS) will be inactive, which is a major safety concern. The brake pedal sensor issue could affect brake light operation and stability control performance.
Is this a difficult part for a DIYer to replace?
The physical replacement is straightforward for someone with basic mechanical skills. However, the final programming steps (airbag and brake relearn) require a professional scan tool. If you don’t have one, you should plan to have a local shop complete these final steps for you.
Will this fix my specific electrical problem?
This module resolves issues directly caused by a failing BCM. While the symptoms listed are common indicators, proper vehicle diagnosis is always recommended to confirm the BCM is the root cause before ordering.
What information do you need from me?
After your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your vehicle. This is essential for us to program the module correctly for your specific options and features.
