Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2010 Cadillac Escalade or another GM vehicle? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or even a vehicle that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can be a serious safety concern.
This replacement Body Control Module is the definitive, hassle-free solution. We take the guesswork and expensive dealership trips out of the equation. Before we ship the module, our technicians will program it with the latest GM software updates, specifically matched to your vehicle’s VIN. This means it arrives at your door ready for installation, designed to restore the precise electronic functions your vehicle had when it left the factory. Get your vehicle’s comfort and convenience features working reliably again.
A Technician’s Notebook
I once had a 2010 Yukon Denali in the shop with a textbook case of BCM failure. The customer reported that the radio would turn on by itself, the door locks would cycle while driving, and the low beams wouldn’t work. A scan showed a dozen communication error codes (U-codes) pointing to the BCM. After confirming power and grounds were good, we knew the module was the issue. Swapping in a pre-programmed BCM like this one resolved all issues in under an hour. Without the pre-programming, that job would have meant a tow to the dealer and an extra $200+ bill for the customer.
Common Signs of a Failing BCM
If you’re experiencing any of these symptoms, a failing Body Control Module is the likely cause. Replacing your faulty BCM can resolve these common issues:
- ✔ Intermittent or non-working power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers activating on their own or not functioning when needed.
- ✔ Multiple unrelated warning lights on the dashboard (e.g., ABS, Airbag, Traction Control).
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ Rapid battery drain while the vehicle is parked.
A Straightforward Guide to Your BCM Installation
Replacing the BCM is a manageable job for a confident DIYer. While the location varies by model (check your service manual), the general process is similar. For a 2010 Escalade, the BCM is typically located under the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
- Locate the Module: Find the old BCM. It’s often secured with a few bolts or clips and may be behind a lower dash panel.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, remove the old module.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical harnesses. You should hear a ‘click’ as they lock in place.
- Reconnect Power: Re-attach the negative battery terminal.
- Post-Installation Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc. Note that some vehicles may require additional relearn procedures as outlined below.
Important Post-Installation Notes
While this module is programmed for your VIN, some vehicle systems may need to be re-synced after installation. These are standard procedures and can often be performed with a high-end bidirectional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to clear any traction control warnings.
- Disclaimer: Always refer to a factory service manual for your specific vehicle for detailed instructions and torque specs.

No. There is no core charge for this part. You can keep your original module.
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information to program the module correctly.
In most cases, no. Our VIN programming handles the primary functions. However, as noted, some vehicles may require an additional relearn procedure for the airbag or brake pedal position sensor, which requires a professional scan tool.
If your part number is included in our cross-reference list in the description, this module is the correct, updated replacement for your vehicle. We program it to function perfectly for your specific model.
Yes, a faulty BCM is a very common cause of issues with the GM Passlock and other anti-theft systems. This pre-programmed module is designed to restore proper communication and resolve those errors.
