Is Your 2015 Silverado Plagued by Electrical Gremlins?
The Body Control Module (BCM) is the central nervous system for your truck’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 the BCM begins to fail, it can cause a cascade of bizarre and frustrating electrical issues that can be difficult to diagnose. If your truck is acting possessed, a faulty BCM is a likely culprit.
From the Diagnostic Bay
We had a 2015 Silverado 1500 in the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome lights would flicker while driving, and occasionally the turn signals would stop working altogether. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing towards the BCM. Instead of a costly and complex replacement at the dealership, we provided a programmed BCM using our cloning service. After a straightforward installation, all the strange electrical issues were gone, and the truck was back to normal. It’s a classic case of a failing BCM creating symptoms that seem unrelated.
Common Failure Symptoms of a Bad BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security system acting up, causing alarm to go off randomly or a no-start condition.
- ✔ False warnings on the dashboard, such as “Service StabiliTrak” or other system alerts.
- ✔ Radio or infotainment system turning on/off or behaving erratically.
- ✔ Key fob not working consistently.
- ✔ Complete loss of power to multiple accessory systems at once.

Post-Installation Procedures
While our goal is a seamless installation, some GM vehicles may require minor recalibration procedures after the BCM is installed. These are often simple and can sometimes be done without a specialized tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and to prevent issues with the traction control system.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that controls most of your vehicle’s non-engine-related functions. This includes power windows, locks, lights, wipers, security system, and various other comfort and convenience features.
Why is this cloning service better than buying a new BCM?
Our cloning service transfers your vehicle’s original data, making the replacement plug-and-play. A new BCM from the dealer is a blank slate and requires expensive, specialized programming to learn your vehicle’s keys, mileage, and specific options. Our service saves you that time, cost, and hassle.
Will I need to get my keys reprogrammed?
No. Because we clone the data from your original module, the replacement BCM will recognize your existing keys. This is a major benefit of our service.
What is the turnaround time for this service?
We typically program and ship your replacement module within 24-48 hours of receiving your original BCM. We then ship it back to you with tracking.
Is this installation difficult?
On the 2015 Silverado 1500, the BCM is located under the steering column. It involves removing a few trim panels and disconnecting electrical connectors. It is a manageable job for a DIYer with basic tools, but we always recommend consulting a service manual or professional if you are unsure.
What if my original BCM is completely dead or unreadable?
In most cases, even with significant internal failure, we can still extract the necessary data. If you suspect your module is severely damaged (e.g., water or fire damage), please contact us before ordering to discuss options.
