Restore Your Truck’s Electrical System with a Hassle-Free Solution
Are you chasing electrical gremlins in your truck? Flickering dashboard lights, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s comfort and convenience features. When it fails, it can make your truck frustrating to operate. This isn’t just an inconvenience; it can lead to a no-start condition, leaving you stranded. Instead of facing a costly dealership visit and complex programming, we offer a straightforward, reliable fix.
This listing is for a replacement BCM, compatible with part numbers like 13594692 and 13591519, that comes ready for installation thanks to our professional cloning service. You simply send us your original BCM. We then transfer all the critical information—like your vehicle’s VIN, mileage, and specific options—to this replacement module. The result? A true plug-and-play component that restores full functionality without any additional programming required on your end. It’s the most efficient way to get your truck back on the road.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Silverado 2500 with a perplexing issue: the radio would randomly turn off, the driver’s side power window wouldn’t work, and the remote key fob was unresponsive. They had already replaced the battery and checked all the fuses. Diagnostics showed several communication error codes (U-codes) pointing to the BCM. In my shop, I’ve seen this exact pattern dozens of times. Internal corrosion or a failed processor on the BCM board disrupts the low-speed data network, causing these seemingly unrelated systems to fail. By installing a cloned 2015 Sierra 2500 BCM, we restored communication between all modules and resolved every symptom in under an hour of shop time, saving the customer hundreds compared to the dealership’s quote.
Is Your GM Vehicle Showing These Symptoms?
- âś” Power windows, locks, or mirrors operate intermittently or not at all.
- âś” Interior or exterior lights flicker, stay on, or fail to turn on.
- âś” The anti-theft or security system light is illuminated, preventing the engine from starting.
- âś” The horn honks unexpectedly or doesn’t work.
- âś” Your key fob is no longer recognized by the vehicle.
- âś” Multiple random warning lights appear on the instrument cluster.
- âś” Communication error codes like U0140, U0155, or B1001 are present.
A Straightforward Guide to Installation
- âś” Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- âś” Locate the BCM: On most GM trucks and SUVs like the Sierra or Tahoe, the BCM is located under the driver’s side of the dashboard, near the steering column or left firewall. Consult a service manual for the exact position on your model.
- âś” Remove the Old Module: Carefully disconnect the electrical connectors. They have locking tabs that need to be pressed to be released. Once disconnected, unbolt or unclip the module from its mounting bracket.
- âś” Ship Us Your Original: After your purchase, we will provide instructions for shipping your original BCM to our facility. Please package it securely.
- âś” Install the Cloned BCM: Once you receive the programmed replacement from us, simply mount it in place and reconnect all the electrical connectors. Ensure they click securely into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair is successful.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair for most functions, some vehicle safety systems may require a ‘handshake’ with the new module. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on 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 new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure correct brake light operation and traction control function.
Disclaimer: Specific requirements can vary. Always consult a factory service manual or a qualified technician for guidance. There is no core charge for this service; you can keep your original module.

Frequently Asked Questions
How does the cloning service work?
After you place your order, you will ship your original BCM to us. We use specialized equipment to extract the unique vehicle data and transfer it to the replacement BCM. We then ship the programmed module back to you, ready for installation.
Do I need to get this programmed by a dealer?
No. Our cloning service makes the replacement BCM plug-and-play. This saves you the time, hassle, and expense of a dealership visit for programming.
What happens if I install it and the airbag light comes on?
This is a possibility, as the airbag system (SDM) is highly secure. If the light appears, a technician with a professional scan tool will need to perform a quick ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
Is this a new part?
This is a high-quality, tested, and verified used OEM component that has been inspected to ensure it meets or exceeds factory specifications for performance and reliability.
How long does the whole process take?
Once we receive your original module, our service is typically completed within 1-2 business days. We will then ship the replacement back to you, and tracking will be provided.
What if my original BCM is completely dead or missing?
If your original module is non-communicative or lost, cloning is not possible. Please contact us before purchasing to discuss other potential solutions for your vehicle.
