Programmed 2010 Escalade BCM Body Control Module 15921353

Restore Your GM Vehicle’s Electrical System with a Plug-and-Play Solution

If you’re dealing with bizarre electrical issues in your 2010 Cadillac Escalade—like flickering lights, malfunctioning power windows, or a security system that has a mind of its own—you’re likely facing a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating guessing game. In my 20+ years as a technician, I’ve seen how a single failing module can mimic a dozen different problems, leading to costly and incorrect diagnostic paths. This isn’t just an inconvenience; it can affect vehicle security and safety systems.

This replacement Body Control Module is the definitive, hassle-free solution. We take the guesswork and dealership expense out of the equation. Before we ship it, we program the module with the latest GM software, using the specific VIN from your vehicle. This means it arrives at your door ready for installation, saving you hundreds in programming fees and a trip to the service center. By installing our pre-programmed 2010 Escalade BCM, you’re not just replacing a part; you’re restoring the seamless, reliable functionality you expect from your vehicle.

Common Signs of a Failing BCM

• ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights).
• ✔ Power windows, locks, or mirrors working intermittently or not at all.
• ✔ The security system or keyless entry failing to operate correctly.
• ✔ Instrument cluster warning lights (like the airbag or ABS light) staying on.
• ✔ Communication Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-codes indicating loss of communication with the BCM.
• ✔ A vehicle that won’t start due to the anti-theft system not recognizing the key.
• ✔ Horn honking randomly or not working when pressed.

Your Straightforward BCM Installation Guide

1. ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system capacitors to discharge.
2. ✔ Locate the BCM: On the 2010 Escalade, 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.
3. ✔ Disconnect the Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed before pulling. Never force a connector.
4. ✔ Remove the Old BCM: Unbolt or unclip the old module from its mounting bracket.
5. ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
6. ✔ Reconnect the Battery: Re-attach the negative battery terminal.
7. ✔ Perform Post-Install Checks: Start the vehicle and test all body functions (lights, windows, locks, etc.). Note that some vehicles may require the additional procedures mentioned below for full functionality.

Important Post-Installation Notes

While our programming handles the vast majority of the setup, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal. Specifically:

• Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional scan tool and ensures the safety system is properly synchronized.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
