If you’re dealing with bizarre electrical issues in your truck—like power windows with a mind of their own, flickering dash lights, or a security system that prevents your engine from starting—you’ve likely met the frustrating reality of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can create a cascade of problems that are maddening to diagnose. Forget the expensive trip to the dealership and the days of vehicle downtime. We offer a simple, reliable, and cost-effective solution.
This is for a professionally programmed BCM, ready for installation in your vehicle. Our service is straightforward: you purchase this listing, and we’ll provide instructions for shipping your original BCM to our facility. Once we receive it, our expert technicians will clone all the essential data—including VIN, mileage, and key programming—onto this replacement module. We then ship the ready-to-install BCM back to you. This process makes the replacement completely plug-and-play, saving you hundreds in dealership programming fees.
A Technician’s Notebook: The Case of the Haunted Truck
A few months back, a 2015 Sierra 2500 was towed into my bay. The owner was at his wit’s end. The radio would turn on and off, the driver’s side window wouldn’t work, and the horn would randomly blare. He’d already replaced the battery and checked all the fuses. A quick scan showed a slew of communication codes (U-codes) pointing to the BCM. After popping off the kick panel, I found the classic sign: evidence of water intrusion from a leaky windshield seal. The corrosion on the BCM board was causing intermittent shorts, creating the ‘haunted’ behavior. By cloning his original BCM, we preserved all his settings and got him a reliable fix without the dealer’s hefty price tag for a new module and programming.
Is Your Truck Exhibiting These Electrical Gremlins?
A failing BCM can manifest in numerous ways. If you’re seeing any of these signs, your BCM is the most likely culprit:
- ✔ Erratic or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, causing a no-start condition.
- ✔ Dashboard gauges behaving incorrectly or not working at all.
- ✔ Horn, wipers, or radio activating unexpectedly.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, or B1001.
- ✔ False warnings appearing on the driver information center (DIC).
Your Straightforward Path to a Reliable Fix
Our process is designed to be as simple as possible for both DIY mechanics and professional shops. Here’s how you get your truck back in top shape:
- Step 1: Place your order. We will contact you with secure, insured shipping instructions for sending us your original BCM.
- Step 2: Carefully remove your original BCM. It’s typically located under the steering column or on the driver’s side firewall/kick panel area.
- Step 3: Ship your module to us. Once it arrives, our technicians perform the cloning service within 1-2 business days.
- Step 4: We ship your newly programmed replacement BCM back to you with tracking information.
- Step 5: Install the replacement module. Since it’s cloned, it’s plug-and-play. Reconnect your battery and start your vehicle.
Important Post-Installation Information
While our cloning service makes this a near-seamless swap, some vehicle systems may require a ‘handshake’ with the new module. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the airbag system with the BCM.
- 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 functionality.
- Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is the process of reading all the critical, vehicle-specific data from your original BCM and writing it directly onto the replacement module. This includes the VIN, security information, and other settings, making the new part work in your truck without needing dealer programming.
How long does the programming and shipping process take?
We typically complete the cloning service within 24-48 hours of receiving your original module. The total turnaround time will depend on the shipping speed you choose. We will provide you with a return tracking number as soon as it ships.
Do I need to send my keys with the module?
No, you do not need to send your keys. Our cloning process transfers all the necessary key data from your old BCM to the new one, so your existing keys will work seamlessly upon installation.
What if the airbag light comes on after I install the new BCM?
This is a known possibility. It simply means the BCM and the airbag system (SDM) need to be re-synced. A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is this a guaranteed fix for my truck’s problems?
This service corrects all issues directly caused by a faulty BCM. If your vehicle’s symptoms match those of a failed BCM, this is the definitive solution. However, it will not fix problems originating from other parts, like a bad sensor or wiring harness.
Is there a core charge for this part?
No, there is no core charge. We need your original module to perform the cloning service, but you are not required to leave it with us. You can keep your original module after the service if you wish.
