Is Your Vehicle Plagued by Bizarre Electrical Issues?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and locks to the interior lights, security system, and even the instrument cluster. When the BCM in your 2015 GMC Yukon, Chevy Silverado, Cadillac Escalade, or other compatible GM vehicle begins to fail, it can create a cascade of frustrating and seemingly unrelated problems. You might be dealing with a dead battery every morning, flickering lights, or features that work intermittently. These aren’t just annoyances; they can compromise your vehicle’s safety and reliability.
The Simple, Dealer-Free Solution: Our BCM Programming Service
Replacing a BCM isn’t as simple as swapping out the old part for a new one. A new module from the dealership is a blank slate and requires expensive, specialized programming to sync it with your vehicle’s unique VIN and security information. Our service completely bypasses this hassle. We offer a pre-programmed 2015 Yukon BCM by cloning the data from your original unit. The process is straightforward:
- Place your order for this service.
- We will contact you with instructions to ship your original BCM to our facility.
- Our expert technicians will transfer all the critical data—including VIN, mileage, and key programming—from your module to a replacement unit.
- We ship the fully programmed, ready-to-install BCM back to you.
This method ensures a true plug-and-play installation. Once you receive the module, you simply install it, and your vehicle’s electronics are restored to proper working order without any additional programming or dealer intervention.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic instrument cluster behavior, with gauges dropping out or warning lights flashing.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ A vehicle security system that malfunctions or prevents the car from starting.
- ✔ Horn honking unexpectedly or not working when needed.
- ✔ Unexplained parasitic battery drain that kills your battery overnight.
- ✔ HVAC (heating and air conditioning) controls not responding.
Installation and Post-Install Considerations
Installation is typically straightforward, as the BCM is often located under the driver’s side dashboard. Once our programmed module is installed, most vehicles will function perfectly. However, in some specific cases, minor follow-up procedures may be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be required to ensure correct operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like lights, windows, locks, security, wipers, and the instrument cluster.
How does your programming service work?
You purchase the service and mail your original BCM to us. We extract the unique data from your module and flash it onto a fully tested replacement unit. We then ship the programmed replacement back to you, ready for installation.
Is this part truly plug-and-play?
Yes, because we clone your vehicle’s original data, the replacement module is plug-and-play. It eliminates the need for expensive dealership programming. In rare cases, a minor relearn procedure like for the airbag system may be needed, as noted in the description.
Why is my airbag light on after installing the BCM?
The BCM communicates with the airbag system (SDM). Sometimes, they need to be electronically re-introduced. A technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
What happens if I install a BCM from a junkyard without programming?
An unprogrammed BCM from another vehicle will cause major issues. It has the wrong VIN and security information, which can prevent the car from starting, disable features, and cause communication errors between modules. Our service prevents all of these problems.
How long does the entire process take?
Once we receive your original module, our programming service is typically completed within 1-2 business days. The total time will depend on shipping times to and from our facility. We will provide you with a tracking number as soon as your programmed module is on its way back to you.
