Is Your GM Vehicle Plagued with Bizarre Electrical Issues?
If you’re experiencing a frustrating array of problems like flickering lights, malfunctioning power windows and locks, intermittent no-start conditions, or random warning lights on your dash, the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s electronic accessories, and when it malfunctions, it can create chaos. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. Don’t let a faulty module keep you guessing. We offer a reliable, straightforward solution to get your vehicle back to 100%.
From the Diagnostic Bay
We recently had a 2015 Chevy Tahoe in the shop with a classic case of BCM failure. The customer reported that the interior lights would stay on, the radio would randomly shut off, and occasionally, the truck wouldn’t start, despite having a new battery. After running diagnostics, we confirmed communication errors with the BCM. Instead of a costly trip to the dealer for a new module and programming, we performed our cloning service. By transferring the data from his original, faulty BCM to a replacement unit, we had him back on the road the same day with a simple plug-and-play install. All symptoms were gone, and the customer saved hundreds of dollars.
Common Symptoms of a Failing BCM
- ā Intermittent or non-functional power windows, door locks, or mirrors.
- ā Erratic behavior from interior or exterior lights (flickering, staying on, or not working at all).
- ā Instrument cluster gauges behaving abnormally or warning lights appearing without cause.
- ā Vehicle security system acting up, preventing the car from starting.
- ā Radio or infotainment system randomly turning on or off.
- ā Inconsistent A/C and heater blower motor operation.
- ā Communication error codes when scanned with a diagnostic tool.
Solving Your 2015 Tahoe BCM Problems with Our Cloning Service
The dealership solution involves purchasing a brand-new module and paying for several hours of labor to program it to your vehicle’s specific VIN and options. Our service eliminates that hassle and expense. We take the critical data from your original BCMāincluding the VIN, mileage, and security informationāand flash it directly onto this replacement module. The result is a unit that is a perfect electronic match for your vehicle.

Post-Installation Procedures
While our goal is a seamless plug-and-play experience, some modern vehicles require a final handshake between modules. After installing your programmed 2015 Tahoe BCM, you may need to perform the following procedures:
- 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. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary 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 does this BCM programming service include?
This service includes a quality tested, replacement BCM that is programmed with your vehicle’s original data. We transfer the VIN, mileage, and security information from your old module to the new one, making it ready for installation.
Why do I need to send my original BCM to you?
Your original BCM contains the unique software and security keys required for your vehicle to operate correctly. By cloning this data, we ensure the replacement module is a perfect match, avoiding the need for expensive dealer programming.
Is this a plug-and-play solution?
Yes, in over 95% of cases, the module is completely plug-and-play. In rare instances, as noted in the description, a simple relearn procedure like an airbag sync or brake pedal position relearn may be required using a professional scan tool.
What happens if I have an airbag light after installation?
An airbag light is the most common relearn needed. It simply means the new BCM needs to be electronically introduced to the airbag module. A technician with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How long does the entire process take?
Once we receive your original module, our programming service typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We always ship the completed module back promptly with tracking.
