Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re experiencing a host of bizarre and frustrating electrical issues in your vehicle, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and interior lights to the security system. When it starts to fail, it can create a cascade of problems that seem unrelated and are often difficult to diagnose, leading to costly and unnecessary repairs.
We had a 2015 Sierra 1500 come into the shop that was driving the owner crazy. The radio would cut out intermittently, the driver’s side power window had a mind of its own, and the key fob would only work sporadically. The owner had already replaced the battery and checked all the fuses. A quick scan with a professional tool revealed multiple U-codes, indicating a loss of communication between modules. All signs pointed to the BCM. Instead of a complex and expensive rewiring job at the dealership, we provided a programmed BCM using our cloning service. The physical swap took less than 30 minutes, and instantly, every single electrical issue was resolved. The customer was thrilled to have their truck back to normal without the dealership hassle or cost.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior dome lights, headlights, or taillights staying on or not turning on at all.
- ✔ The security system engaging randomly, causing a no-start condition.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ Key fob and remote start features working intermittently or not at all.
- ✔ Climate control system malfunctions.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors (U-codes).
The Plug-and-Play Solution: A Programmed 2015 Yukon BCM
Forget about towing your vehicle to a dealership and paying hundreds for diagnostics and programming. Our professional cloning service provides a simple, cost-effective, and permanent solution. We take a replacement BCM and transfer the exact data from your original, failing module. This includes your vehicle’s unique VIN, mileage, security information, and specific options. The result is a module that is 100% plug-and-play. Simply install it, and your vehicle’s electronics will be fully restored.

Important Post-Installation Information
While our goal is a seamless installation, some GM vehicles may require minor recalibration procedures after the BCM is replaced. These are typically simple steps that can be performed with a capable diagnostic tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called “Setup SDM Primary Key in BCM” is required. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) to clear the light. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lighting, the alarm system, remote keyless entry, and even the wipers.
Why is your programming service required for this part?
GM BCMs are encoded with your vehicle’s specific Vehicle Identification Number (VIN) and security data. A new or used BCM from another vehicle won’t work correctly without being programmed. Our cloning service transfers this vital information, making the replacement module a true plug-and-play component, saving you from a costly trip to the dealer.
Is this part difficult to install myself?
The physical installation is generally straightforward for someone with basic mechanical skills. The BCM is typically located under the driver’s side dashboard. The main challenge is the electronic setup, which our programming service completely eliminates for you.
What happens if the airbag light comes on after I install it?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to send my keys along with my BCM?
No, you do not need to send us your keys. All the necessary immobilizer and key data is stored within your original BCM, and we will transfer it directly to the replacement module during the cloning process.
How long does the entire process take?
Once we receive your original BCM, our service typically takes 1-2 business days. We then ship your modules back to you. Total turnaround time will depend on shipping speeds to and from our facility.
