End the Electrical Gremlins in Your GM Vehicle
Is your 2009-2012 Chevrolet Traverse acting possessed? One day the power locks don’t work, the next the radio is dead, and the dash is lit up with random warnings. These frustrating, intermittent electrical problems are classic signs of a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and security features, when the BCM goes bad, it can make your daily drive a nightmare. This isn’t just an annoyance; it can affect vehicle security and safety systems.
Instead of facing a costly trip to the dealership for a new module and expensive programming fees, we offer a simple, reliable solution. This is a direct replacement BCM featuring our expert Cloning Service. We transfer the critical data from your original module to this replacement unit, making it a true plug-and-play fix. No additional programming or dealer visits are required to get your vehicle back to 100%.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Traverse with a baffling set of symptoms. The power liftgate worked intermittently, the driver’s side window wouldn’t go down, and the security light would flash, sometimes causing a no-start condition. They had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I saw multiple ‘Lost Communication’ codes (U-codes) pointing to the BCM. In my 20+ years of experience, water intrusion is a common killer of these modules, often from a leaky windshield seal dripping onto the dash-mounted BCM. By providing a cloned BCM, we had the customer back on the road the same day their part arrived, bypassing weeks of dealership back-and-forth and saving them hundreds.
Common Signs of a Failing BCM
If you’re experiencing any of these issues, a faulty BCM is the likely culprit. A proper diagnosis is key, but these are the tell-tale symptoms we see in the shop every day.
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system acting up, causing alarm or no-start problems.
- ✔ Radio or infotainment system randomly shutting off or not powering on.
- ✔ Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other communication errors.
- ✔ Wipers behaving erratically or not parking in the correct position.
Your Straightforward BCM Installation Guide
Installing your cloned 2009-2012 Traverse BCM is a manageable job for a DIYer with basic tools. The BCM on the Traverse is typically located on the left (driver’s) side of the dash, often behind the lower trim panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- Access the Module: Carefully remove any trim panels or covers necessary to access the BCM. It’s usually held in place by a few small bolts or clips.
- Disconnect and Remove: Gently unplug the electrical connectors from the old BCM. Pay attention to the locking tabs on the connectors to avoid damage. Once disconnected, remove the old module from its mounting bracket.
- Install the New BCM: Mount your new, cloned BCM into the vehicle. Reconnect all electrical connectors, making sure they click securely into place.
- Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Start the vehicle and test all functions: windows, locks, lights, radio, etc., to confirm the repair.
Important Post-Installation Steps
Our cloning service makes this process as simple as possible. However, due to the complexity of modern vehicle systems, a couple of additional steps might be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the safety systems and is only required if the light is illuminated.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
How does the cloning service work?
After you place your order, you will send us your original BCM. Our technicians will extract the unique data (including VIN, mileage, and key information) and flash it onto the replacement module. This makes the new part plug-and-play, with no need for dealer programming. We then ship both your original module and the ready-to-install replacement back to you.
Do I need to send you my VIN?
No, providing your VIN is not necessary for the cloning service. All the required information is contained within your original module, which is why you must send it to us for the data transfer.
Will I need my keys reprogrammed?
No. Because we clone the data from your original BCM, the replacement module will recognize your existing keys. This is one of the biggest benefits of our service, saving you time and money.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still retrieve the necessary data. If your module is severely damaged (e.g., by fire or major water damage), data recovery may not be possible. Please contact us before ordering if you suspect this is the case.
Is this a difficult part to install myself?
For someone with basic mechanical skills and tools, this is a very manageable job. The BCM is usually located inside the cabin and is easy to access. Following our guide and disconnecting the battery are the most important steps.
