Is Your GM Vehicle Experiencing Strange Electrical Issues?
The Body Control Module (BCM) is the central command center for your vehicle’s body electronics. It manages a wide array of functions, including power windows, door locks, interior and exterior lighting, security systems, and even communicates with other critical modules. When your BCM begins to fail, it can create a cascade of confusing and frustrating problems that can be difficult to diagnose. Instead of paying for expensive diagnostic time and dealership programming, our mail-in programming service provides a simple, effective, and affordable solution.
The Plug-and-Play Solution for Your 2015-2016 GM BCM
This listing is for a replacement Body Control Module that is professionally programmed with your vehicle’s original data. We perform a direct clone of your factory BCM, transferring all the essential information, including the VIN, security keys, and specific option configurations. This process ensures that the replacement module is a 100% plug-and-play part, eliminating the need for any additional programming or calibration from a dealer. You can restore your vehicle’s functionality right in your own garage.
From the Diagnostic Bay
We had a 2015 GMC Sierra 1500 in the shop that was driving the owner crazy. The dome lights would randomly turn on while driving, the radio would stay on after the key was removed, and the power locks worked intermittently. The owner had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication loss codes with various accessories. This pointed directly to the central hub – the BCM. Instead of a complex rewiring job, a cloned BCM solved every single issue. It’s a perfect example of how one failing module can create a host of seemingly unrelated symptoms.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Vehicle’s security system or keyless entry malfunctioning.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Warning lights on the dashboard, such as the airbag or security light.
- ✔ Rapid battery drain while the vehicle is parked.
- ✔ Communication errors with diagnostic scan tools.

Important Post-Installation Steps
While our goal is a seamless installation, some GM vehicles may require minor recalibration procedures after the BCM is replaced. These are simple procedures that can often be performed with a high-end diagnostic tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘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 correct brake light operation and traction control performance.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM cloning service?
BCM cloning is a process where we extract the unique software, VIN, and security data from your original module and transfer it to a replacement unit. This makes the new module an identical twin to your old one, ensuring it works perfectly with your vehicle without any dealer intervention.
Why is this better than just buying a used BCM?
A standard used BCM from a salvage yard is programmed to a different vehicle. Installing it will cause a VIN mismatch, activate the anti-theft system, and prevent your vehicle from starting. Our cloning service makes the replacement BCM fully compatible with your specific car or truck.
How long does the service take?
We pride ourselves on a fast turnaround. Once we receive your original BCM, the programming and shipping process is typically completed within 1-2 business days.
Do I need to do any programming myself?
No. The module you receive back from us will be 100% plug-and-play. Simply install it, and you’re ready to go, aside from potential minor relearn procedures mentioned above.
What if my original BCM is water damaged or won’t communicate?
In many cases, we can still recover data from damaged modules. However, if your BCM is severely compromised (e.g., fire damage, completely unresponsive), please contact us before ordering to discuss potential options.
