Programmed Body Control Module for 2010 Escalade EXT 25847588 | VIN Matched

If you’re dealing with bizarre electrical issues in your 2010 Cadillac Escalade EXT, you’re not alone. As a technician with over two decades of experience, I’ve seen it all: power windows with a mind of their own, dashboard lights flickering like a disco, or the security system preventing you from starting your own truck. These frustrating gremlins often point to one culprit: a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it starts to go, it can cause a cascade of confusing problems.

Don’t let a faulty BCM sideline your luxury truck. This is a direct-replacement Body Control Module, arriving at your door fully programmed to your vehicle’s specific VIN. We load it with the latest GM factory software, ensuring it communicates flawlessly with your Escalade’s other systems right out of the box. This eliminates the need for an expensive trip to the dealership for programming, saving you significant time and money.

Common Signs of a Failing BCM

A bad BCM can manifest in numerous ways. In my shop, I’ve seen these modules cause some of the most difficult-to-diagnose electrical problems. If your truck is experiencing any of the following, a faulty BCM is the likely cause:

• ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
• ✔ The security system or keyless entry working intermittently or not at all.
• ✔ Warning lights on the instrument cluster (like ABS, Airbag, or Traction Control) illuminating for no reason.
• ✔ Inaccurate gauge readings or a completely dead instrument panel.
• ✔ Communication failure Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-codes, indicating a loss of communication with the BCM.
• ✔ The vehicle failing to start, even with a good battery and starter.

Your Straightforward Installation Guide

Replacing the 2010 Escalade EXT BCM is a manageable job for a confident DIYer. The module is typically located under the driver’s side of the dashboard, near the steering column.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
2. Locate the BCM: On your Escalade EXT, look under the driver’s side dash. You may need to remove a lower dash panel for access. The BCM is a small black box with several large electrical connectors.
3. Disconnect and Remove: Carefully unplug all wiring harnesses from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
4. Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the wiring harnesses, ensuring each one clicks into place.
5. Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, etc.—to confirm the repair.

Important Post-Installation Note: In some cases, additional vehicle-specific relearn procedures may be required. For example, if your airbag light is on, a scan tool procedure called ‘Setup SDM Primary Key in BCM’ is needed. A ‘Brake Pedal Position Relearn’ might also be necessary. These are standard procedures for any professional technician’s scan tool.
