Restore Full Functionality to Your GM Vehicle

Are you dealing with baffling electrical issues in your 2010 Cadillac Escalade? Intermittent power windows, flickering lights, a security system that acts up, or strange warning messages on the dash are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features, and when it malfunctions, it can make driving a frustrating experience. This isn’t just about inconvenience; a faulty BCM can affect vehicle security and safety systems.

We offer a straightforward and reliable solution. This listing is for a replacement Body Control Module that comes ready for installation thanks to our professional cloning service. Instead of paying for expensive dealership programming and diagnostics, you send us your original BCM. We then transfer its unique data—including key information, mileage, and specific options—directly onto this replacement module. The result is a true plug-and-play part, specifically prepared for your vehicle’s VIN.

Common Signs of a Failing BCM

If you’re experiencing any of the following, a faulty BCM is the likely culprit. In my 20+ years of experience, these symptoms are the most common indicators, often accompanied by communication codes like U0140.

• ✔ Erratic or non-working power windows, door locks, and mirrors.
• ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
• ✔ The security system or alarm randomly activating or preventing the car from starting.
• ✔ Horn honking unexpectedly.
• ✔ Instrument cluster gauges behaving erratically or going dark.
• ✔ Communication errors with other modules on the vehicle’s network.
• ✔ Remote keyless entry failure.

Your Straightforward BCM Installation Guide

With our cloning service, the physical swap is all you need to do. For a 2010 Escalade, the BCM is typically located under the driver’s side dash, 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 most compatible SUVs and trucks like the Escalade, Tahoe, and Yukon, you’ll need to remove the lower dash panel beneath the steering wheel to gain access.
3. Disconnect the Module: Carefully unplug all electrical connectors from the old BCM. The connectors have locking tabs that need to be pressed to release them. Do not force them.
4. Swap the Modules: Unbolt or unclip the old BCM from its mounting bracket and install the new, programmed module in its place.
5. Reconnect and Test: Plug all connectors firmly into the new BCM. Reconnect the battery terminal. Turn the key to the ‘On’ position and test all functions: windows, locks, lights, etc.

Important Post-Installation Information

Our cloning service handles the vast majority of programming needs. However, in some GM vehicles, additional steps may be required to ensure all systems communicate correctly after the new module is installed.

• Airbag System Sync: If the airbag warning light is illuminated after installation, a simple “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional scan tool and ensures the new BCM is correctly synced with the airbag system. This is only necessary if the light is on.
• Brake Pedal Position Relearn: On certain models, the traction control or ABS light may illuminate. A Brake Pedal Position (BPP) sensor relearn procedure may be required to restore proper function.
