Is Your GM Vehicle Experiencing Strange Electrical Problems?
The Body Control Module (BCM) is the central command center for your vehicle’s body electronics. It manages a vast array of functions, from your power windows and door locks to the interior lights, security system, and even communication between other modules. When the BCM starts to fail, it can cause a cascade of confusing and frustrating issues that can be difficult to diagnose. If your Cadillac, Chevy, or GMC is acting possessed, a faulty BCM is a likely culprit.
The Simple, Dealer-Free Solution
Replacing a BCM typically means a trip to the dealership for expensive and time-consuming programming. Our unique cloning service eliminates that hassle entirely. We transfer the critical data—including VIN, mileage, and key information—from your original BCM directly onto this replacement unit. The result is a true plug-and-play module that is ready for installation right out of the box, saving you hundreds of dollars and significant downtime.
From the Diagnostic Bay
We had a 2015 Silverado in the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome light would flicker, and occasionally the truck wouldn’t start, showing a ‘Service Theft Deterrent System’ message. The owner had already replaced the battery and checked all the grounds. After hooking up our diagnostic tool, we saw multiple communication loss codes with the BCM. Instead of just selling him a new module that would need programming, we performed a data transfer from his old, failing unit to a replacement. He installed it in his driveway in under an hour, and every single bizarre electrical issue was gone for good. This service saved him a tow to the dealer and a massive bill.
Common Symptoms of a Failing 2015-2016 ATS BCM
A failing Body Control Module can manifest in numerous ways. If you’re noticing any of the following, it’s time to consider a replacement:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights not working correctly (staying on, not turning on, or flickering).
- ✔ The security system acting erratically, causing no-start conditions or false alarms.
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ Warning lights appearing on the dash, such as for the airbag or traction control system.
- ✔ Remote keyless entry failing to work.
- ✔ Complete loss of communication with the BCM when using a diagnostic scan tool.
How Our Programming Service Works
Our process is designed to be as simple and straightforward as possible for you.
- Place Your Order: Purchase this BCM listing. Ensure your contact information is up-to-date.
- We Contact You: We will reach out with clear instructions and a shipping address for you to send your original BCM to us.
- Ship Your Module: Securely package and ship your original BCM to our facility.
- We Clone the Data: Upon receipt, our technicians will perform a full data transfer from your original module to the replacement unit.
- Receive Your Ready-to-Install BCM: We ship the newly programmed BCM back to you. You’ll receive tracking information once it’s on its way. Installation is as simple as swapping the modules.
Post-Installation Procedures
While our cloning service makes this a plug-and-play part, some vehicle systems may require a simple sync or relearn procedure after the new BCM is installed. This is standard for many electronic repairs.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the airbag system with the new BCM and can be performed with a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control functionality.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly is ‘cloning’ or ‘programming’?
We extract the vehicle-specific software and security data (like the VIN and key codes) from your original BCM and flash it onto the replacement module. This makes the new module an exact digital copy of the old one, allowing your vehicle to accept it without needing any additional programming from a dealer.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary immobilizer and key data is stored within the BCM itself. We transfer this data, so your existing keys will work perfectly with the new module upon installation.
How long does the programming service take?
Once we receive your original BCM, the data transfer process is typically completed and shipped back out within 1-2 business days. You will be notified with tracking information as soon as it is on its way back to you.
Will this fix my specific problem?
This part is a direct solution for a faulty BCM. If your vehicle has been properly diagnosed with a failing BCM, this programmed module will resolve the related issues. It will not fix problems caused by other faulty components, wiring, or sensors.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is not communicating with the vehicle, we can still extract the necessary data directly from the memory chip. Please contact us before ordering if your module is severely damaged by water or fire.
Is there a core charge for this part?
No, there is no core charge. We require your original module to perform the data transfer service, but you are not required to leave it with us. You can keep your original module after the service is complete.
