Is Your GM Vehicle Acting Possessed? It Could Be The BCM.
If your 2015 Silverado, Sierra, Corvette, or other compatible GM vehicle is plagued by bizarre electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and door locks to your interior lights and security system. When it starts to fail, it can create a cascade of frustrating and seemingly unrelated problems that can be difficult to diagnose.
Common Symptoms of a Failing BCM
A faulty BCM doesn’t always fail completely. Often, it begins with intermittent issues that can leave you scratching your head. If you’re experiencing any of the following, it’s time to inspect your Body Control Module.
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on or not turning on.
- ✔ The vehicle’s security system malfunctioning or preventing the engine from starting.
- ✔ The horn honking randomly or not working when pressed.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication errors with other modules, leading to a no-start condition.

Because this module is a direct clone of your original, in most cases, no further action is needed. However, in some instances, you may need a professional scan tool to perform a simple relearn procedure.

Frequently Asked Questions
How does this cloning service work?
You purchase this listing and then ship your original BCM to us. We extract the unique data from your module and transfer it to the replacement unit. This makes the replacement module plug-and-play, as it is an exact electronic copy of your original.
Will I need to have this BCM programmed by a dealer?
No. The entire point of our service is to bypass the need for dealer programming. Because we clone your original data, the vehicle will recognize the replacement module as its own, saving you time and money.
Is this a difficult part to install?
On most trucks like the Silverado and Sierra, the BCM is located under the steering column and is accessible by removing a lower dash panel. It typically involves disconnecting the battery and unplugging several electrical connectors. While it can be a DIY job for someone with moderate experience, we always recommend consulting a service manual or a professional technician.
What is the turnaround time for the service?
We typically program and ship your replacement module within 1-2 business days of receiving your original BCM. Return shipping time will depend on your location and the shipping service selected.
What if the airbag light comes on after I install it?
This can happen occasionally. It requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by most professional repair shops with a high-end diagnostic scan tool. It’s a quick procedure that syncs the BCM with the airbag module.
