Restore Full Functionality to Your GM Vehicle
Are you dealing with bizarre electrical issues in your 2015 Yukon XL 1500? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly prevents your truck from starting? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it falters, it can cause a cascade of frustrating and unpredictable problems. Instead of facing a massive bill and a long wait at the dealership, our programming service offers a simple, reliable, and cost-effective solution.
We provide a fully tested replacement BCM that is programmed with the exact data from your original module. This cloning process makes the installation virtually plug-and-play. You send us your original BCM, we transfer its unique identity—including VIN, mileage, and option configurations—to the replacement unit, and ship it right back to you. This bypasses the complex and expensive programming procedures required by the dealer, getting you back on the road with confidence.
A Technician’s Notebook: The Intermittent Fault Mystery
A customer brought in a 2015 Sierra 1500 with a complaint that drove him crazy: sometimes, the radio wouldn’t turn on, and the driver’s side power window wouldn’t work. Of course, it worked perfectly when it got to my bay. After checking fuses and wiring, I suspected the BCM. These modules often fail internally, causing intermittent data network errors. On these GM platforms, a failing BCM can disrupt communication for seemingly unrelated components. We swapped in a cloned BCM, and the “ghosts” in his machine vanished. This service is the exact fix we used in the shop for a quick, permanent repair.
Common Signs of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The vehicle’s security system engaging incorrectly, leading to a no-start condition.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ Radio or infotainment system randomly shutting off or failing to power on.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-codes.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most 2015 Yukon XL 1500 models, the BCM is located under the driver’s side of the dashboard, near the steering column. Consult a service manual if you have trouble finding it.
- ✔ Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove the fasteners holding the module in place.
- ✔ Install the New Module: Mount your newly programmed BCM in the same location and securely plug in all the electrical connectors. Ensure they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play process, some GM systems may require a final handshake. If your airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ may be necessary on some models to ensure perfect traction control and brake light operation. These are not always required but are important possibilities to be aware of.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we’ll provide instructions for shipping your original BCM to us. Once we receive it, our technicians extract the unique vehicle data and program it onto the replacement module. We then ship the ready-to-install module back to you.
Will I need to program my keys again?
No. Because we clone all the data from your original module, including security information, your existing keys will work immediately upon installation. This is a major benefit over buying a new or used BCM.
Is this a new part?
This is a high-quality, fully tested, and guaranteed used or reconditioned OEM part. This allows us to provide a reliable and affordable solution. Every unit is verified for full functionality before being programmed and shipped.
What is the turnaround time?
We pride ourselves on a fast turnaround. The programming is typically completed and the module is shipped back out within 1-2 business days of us receiving your original BCM.
What if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be synced with the airbag’s Supplemental Deployment Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, a quick task for any qualified shop.
Do I need to send my old part back?
Yes, you must ship your original BCM to us for the data cloning service. However, there is no separate core charge, and we will ship your original module back to you along with the newly programmed one.
