Restore Your Vehicle’s Brain and End Electrical Chaos
Are you battling a storm of strange electrical problems in your GM vehicle? Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or even a car that refuses to start? As a technician with over 20 years of experience, I’ve seen these frustrating issues hundreds of times. The culprit is often a failing Body Control Module (BCM)—the central command center for your vehicle’s comfort and convenience features. A faulty BCM can make your car feel unreliable and unpredictable. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
This is the definitive solution. We offer a professional Cloning Service for your BCM. Instead of selling you a blank module that requires expensive dealership programming and calibration, we transfer the exact data from your original BCM to this replacement unit. This ensures that all your vehicle’s specific settings, key information, and security parameters are perfectly preserved. The result is a truly plug-and-play repair that restores your vehicle’s functionality without the hassle and high cost of dealer intervention. By ordering this 2010 STS Body Control Module cloning service, you’re choosing the most efficient and reliable path back to a fully operational vehicle.
Case Study: A Tricky Diagnosis
A customer brought in their 2011 Chevy Impala last month with a list of bizarre, intermittent symptoms. The radio would turn off randomly, the anti-theft light would flash, and occasionally the car wouldn’t crank. They had already replaced the battery and alternator with no success. After connecting my scan tool, I found a slew of ‘loss of communication’ codes (U-codes) pointing to multiple systems. This is a classic sign of a failing BCM creating network-wide noise. Instead of a complex rewiring job, we performed a BCM clone using this exact service. We transferred the data from his old, failing module to the new one. After a 15-minute installation, every single issue was resolved. The customer was thrilled to have their reliable car back without a massive repair bill.
Common Signs of a Failing BCM
- ✔ Power windows, door locks, or mirrors operate erratically or not at all.
- ✔ The security system light stays on, or the alarm goes off for no reason.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The vehicle won’t start, and you hear a rapid clicking sound (not a dead battery).
- ✔ Diagnostic trouble codes related to communication errors are present (e.g., U0140, U0155).
- ✔ Wipers or the horn activate unexpectedly.
A Straightforward Guide to Installation
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: The Body Control Module’s location varies. On a 2010 STS, it’s typically in the center dash. For other models, it may be under the steering column or behind the dash on the driver’s or passenger’s side. Consult a service manual for your specific vehicle if you’re unsure.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or clips holding the module in place and take it out.
- Install the New Module: Seat the newly cloned BCM into the mounting bracket and secure it. Reconnect the electrical harnesses, ensuring each plug clicks firmly into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test and Verify: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair was successful. Note the post-installation procedures below, as some relearns may be necessary.
Important Post-Installation Steps: While our cloning service makes this a near plug-and-play process, some vehicle systems may require a ‘handshake’ with the new BCM. If your airbag light is on, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. Similarly, a Brake Pedal Position Relearn might be required on some models to ensure proper brake light and stability control function. Always refer to a factory service manual for your specific vehicle’s requirements.

Frequently Asked Questions
How does the BCM cloning service work?
After you purchase, you will ship your original BCM to us. We use specialized equipment to read the unique vehicle data from your module and write it directly onto the replacement unit. We then ship both your original module and the ready-to-install replacement back to you.
Will I need to have this module programmed by a dealer?
No. The entire point of our cloning service is to avoid dealer programming. Because the replacement module will contain your car’s original data, the vehicle will recognize it as its own, making the installation plug-and-play.
Is this a guaranteed fix for my car’s problems?
This service corrects issues caused by a faulty BCM. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause before ordering.
What is your core policy? Do you keep my old BCM?
We do not keep your original module. Our service requires your original BCM to extract the necessary data. It will always be returned to you along with the programmed replacement unit.
Why is my airbag light on after installation?
In some GM vehicles, the BCM and the airbag system (SDM) need to be electronically re-synced after a BCM replacement. This is a security feature. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to turn off the light.
What tools are needed for the installation?
Basic hand tools like a socket set or screwdriver are usually all that’s needed to physically swap the module. However, as noted, a professional-grade scan tool may be required for post-installation procedures like the airbag sync or brake pedal position relearn.
