Is Your GM Truck Plagued by Bizarre Electrical Issues?
If you’re dealing with a vehicle that seems to have a mind of its ownāpower windows not working, interior lights flickering, security system acting up, or strange messages on your dashāthe culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. Replacing it isn’t as simple as swapping parts; a new BCM requires expensive programming at a dealership to sync it with your vehicle’s specific VIN and options. Our professional programming service eliminates that hassle entirely.
From the Diagnostic Bay
We had a 2015 Silverado 2500 come into the shop that was driving the owner crazy. The radio would randomly turn off, the driver’s side power window worked intermittently, and the remote start failed half the time. He had already replaced the battery and checked all the fuses. After hooking up our diagnostic scanner, we saw multiple communication errors pointing towards 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, failing BCM to a quality replacement unit, we had him back on the road in a day with all electrical functions fully restored. It’s a common story, and this service is the most effective solution.

Symptoms of a Failing 2015 Sierra 3500 BCM
- ā Power windows, door locks, or mirrors operating erratically or not at all.
- ā Interior or exterior lights (headlights, dome lights) staying on or not turning on.
- ā The security system or alarm randomly activating or preventing the vehicle from starting.
- ā Inconsistent or non-functional remote keyless entry.
- ā False warning lights or messages appearing on the instrument cluster.
- ā Wipers or radio not functioning correctly.
- ā Communication errors with other vehicle modules when scanned with a diagnostic tool.
Post-Installation Procedures
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a simple recalibration after the new BCM is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will be necessary. This requires a professional-grade scan tool to sync the airbag system with the new BCM and clear the light. This is only needed if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure proper operation of the brake lights and 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 the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, locks, lights, security system, wipers, and more. When it fails, these systems can become unreliable.
Is this BCM truly plug-and-play?
Yes. Because we clone the exact data from your original module, the replacement BCM we send you is ready for immediate installation without any need for dealer programming. In some rare cases, a minor relearn procedure may be needed for systems like the airbag or brake pedal sensor.
Why do you need my original BCM?
Your original BCM contains the unique software and coding specific to your vehicle’s VIN and factory-installed options. By cloning this data, we ensure the replacement module works perfectly with your truck’s existing systems, just like the original did.
How long does the programming service take?
We typically complete the cloning process and ship your programmed BCM back to you within 1-2 business days of receiving your original module.
What if the airbag light comes on after I install it?
This can occasionally happen. It requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by any competent repair shop with a professional-grade diagnostic tool. It’s a quick sync procedure to re-establish communication between the BCM and the airbag module.
Is this a better option than buying a used BCM from a junkyard?
Absolutely. A used BCM from another vehicle will not work in your truck without being reprogrammed by a dealer, which is costly and often difficult. Our service provides a part that is already programmed specifically for your vehicle, saving you time, money, and hassle.
