Is Your GM Vehicle Acting Possessed? It’s Probably the BCM.
If your 2015 GMC Yukon, Chevy Tahoe, Silverado, or other compatible GM vehicle is plagued by baffling electrical problems, you’ve likely met the culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. It manages everything from your power windows and door locks to the interior lights, security system, and even communicates with other critical modules. When it starts to fail, the symptoms can be unpredictable and incredibly frustrating, often mimicking a dozen other potential issues.
From the Diagnostic Bay
We recently had a 2015 Sierra 1500 in the shop with a list of complaints that seemed to have no connection. The radio would randomly turn off, the driver’s side window wouldn’t roll down intermittently, and the dome lights would flicker at highway speeds. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication loss codes with various systems, all pointing back to one central point. We identified a failing BCM. Instead of a costly trip to the dealer for a new module and several hours of programming, we used our cloning service. We transferred the data from his old, faulty module to our replacement unit. He was back on the road the next day with all issues resolved, saving him hundreds of dollars and significant downtime.
Common Symptoms of a Failing BCM
- โ Power windows, door locks, or mirrors operating erratically or not at all.
- โ Interior or exterior lights flickering, staying on, or not turning on.
- โ The security system or keyless entry malfunctioning, or the alarm going off for no reason.
- โ The instrument cluster displaying incorrect information or warning lights illuminating randomly.
- โ The vehicle failing to start, even with a good battery and starter.
- โ HVAC (heating and air conditioning) controls not responding.
- โ Communication errors when trying to scan the vehicle with a diagnostic tool.

- โ Receive Your Ready-to-Install BCM: We ship the newly programmed module back to you. Simply install it, and you’re ready to go!
Post-Installation Procedures
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a recalibration or sync procedure after the new BCM is installed. These are typically simple procedures for a qualified technician with a professional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure is needed to sync 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 might be necessary to ensure proper brake light and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is the process of reading the essential vehicle-specific data (like VIN, key information, and security settings) from your original BCM and writing it onto a replacement module. This makes the replacement unit an exact digital copy, allowing it to work in your vehicle without any further programming.
Why do I have to send you my original part?
Your original BCM holds the unique digital fingerprint for your vehicle. We need it to extract this data. Without it, a new module would be a blank slate and would require expensive programming from a dealership, which is what our service helps you avoid.
Is this BCM truly plug-and-play?
Yes, in over 99% of cases. Once we program it with your vehicle’s data, you simply need to install it. In rare instances, a secondary procedure like an airbag sync may be needed, which can be done by any competent shop with a high-end scan tool.
Will my existing keys and remote fobs work?
Absolutely. Because we transfer all the original data, the new BCM will recognize your existing keys and remotes just like the old one did. No need for key reprogramming.
Where is the BCM located on a 2015 GMC Yukon?
On the 2015 GMC Yukon and similar GM trucks/SUVs (Tahoe, Silverado, Sierra), the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column. Always disconnect the battery before attempting removal or installation.
