Is Your Vehicle Plagued by Bizarre Electrical Issues?
Are you dealing with flickering dashboard lights, power windows that won’t cooperate, a security system that acts up, or other strange electronic gremlins in your Chevrolet, GMC, or Cadillac? These aren’t just annoyances; they are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, managing everything from interior lighting and power locks to the instrument cluster and security system. When it starts to fail, it can create a cascade of frustrating and seemingly unrelated problems.
From the Diagnostic Bay
We had a 2015 GMC Sierra in the shop that was driving its owner crazy. The radio would randomly shut off, the dome light would stay on, and the power door locks worked only when they felt like it. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication errors pointing towards a faulty BCM. Instead of a costly trip to the dealer for a new module and programming, we provided a replacement unit programmed with the data from his original. The result? All the electrical gremlins vanished instantly. It’s a perfect example of how a single component can cause widespread issues.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, and mirrors.
- ✔ Dashboard lights flickering, dimming, or staying on unexpectedly.
- ✔ Horn honking randomly or not working at all.
- ✔ Vehicle security system engaging without reason or preventing the car from starting.
- ✔ Inconsistent operation of interior and exterior lighting.
- ✔ Radio or infotainment system turning on and off by itself.
- ✔ False warning messages appearing on the instrument cluster.

Post-Installation Information
While our goal is a 100% plug-and-play experience, some vehicle systems may require a simple sync procedure after installation. This is normal and can often be done with a high-end diagnostic tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will be necessary to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any post-installation steps.

Frequently Asked Questions
Why do I need to send you my original BCM?
Your original BCM contains unique data specific to your vehicle’s VIN, security information (immobilizer), and optional features. By cloning this data to the replacement module, we ensure it works seamlessly with your vehicle without requiring expensive dealer programming.
Is this BCM truly plug-and-play?
Yes, in over 95% of cases, the module is completely plug-and-play. In rare instances, as mentioned above, a simple relearn procedure for the airbag or brake pedal sensor may be required using a professional scan tool.
How long does the programming service take?
Once we receive your original module, our technicians typically complete the programming and prepare your replacement for shipment within 24-48 hours.
What if my original BCM is completely dead or ‘fried’?
Even if your module is non-functional, in most cases, our advanced tools can still extract the necessary data from the memory chips. Please contact us if your module has significant physical damage (e.g., from fire or water) to discuss options.
Do I need to return my old BCM after I receive the replacement?
No, there is no core charge for this service. You only need to send us your original module for the initial data cloning. We will not return the original module unless specifically requested.
