Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Are you dealing with baffling electrical issues in your GM truck or SUV? Flickering lights, intermittent starting, 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). As the central hub for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. The dealership solution often involves expensive diagnostics, a new module, and programming fees that can quickly add up. This is a smarter way to get your vehicle back to 100%.
This offering is for a fully programmed replacement BCM, compatible with part numbers like 13594768 and 13594692. We simplify the repair process through our professional cloning service. You simply send us your original BCM, and we transfer all of its critical data—including VIN, mileage, and key information—to a replacement unit. The module you receive back will be a direct, plug-and-play replacement, eliminating the need for a trip to the dealer for programming. It’s the most efficient and cost-effective way to solve complex BCM-related faults.
A Technician’s Notebook: The Case of the Haunted Sierra
A customer brought in a 2015 Sierra 2500 with a list of complaints that sounded like the truck was possessed. The radio would change stations on its own, the dome light would flicker while driving, and occasionally, the truck wouldn’t start—just a click. There were no engine codes, but the scanner was full of U-codes (U0140, U0155), indicating a loss of communication with the BCM. After verifying the main power and ground connections to the module were solid, we knew the BCM itself was failing internally. Instead of a costly new unit and programming, we performed a cloning service just like this one. The customer had their truck back the next day with all gremlins gone. This service saves both time and money by targeting the exact point of failure.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the culprit. A professional diagnosis is always recommended, but these are strong indicators:
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently.
- ✔ The security system light stays on, preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, or specific body codes (B-codes).
- ✔ Instrument cluster gauges behaving abnormally.
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is designed to be a direct swap. While the exact location can vary slightly, it’s typically found under the steering column or on the driver’s side firewall.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the Original BCM: On most Sierra/Silverado models, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black box with multiple large electrical connectors.
- Remove the Old Module: Carefully release the locking tabs on each electrical connector and pull them straight out. Then, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount the replacement BCM you received from us in the same location. Firmly reconnect all electrical connectors, ensuring they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair was successful.
Important Post-Installation Information
In some cases, additional steps may be required after installation:
- Airbag System Sync: If the airbag warning light is illuminated after the swap, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Certain models may require a brake pedal position sensor recalibration to ensure proper function of the brake lights and traction control system.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any step of the process.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with shipping instructions. You mail your original BCM to us. We then extract the vehicle-specific data and flash it onto a fully tested replacement BCM. We ship the programmed module back to you, ready for installation.
Do I need to send my keys?
No, you do not need to send your keys. Because we are cloning all the data from your original module, the replacement will recognize your existing keys automatically.
Is this a plug-and-play solution?
Yes. Since the replacement BCM is a clone of your original, it requires no additional programming after installation. In rare cases, a specific relearn procedure like for the airbag or brake pedal sensor may be needed, as noted in the description.
What is the turnaround time?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. You will receive a tracking number once it is on its way back to you.
Is there a core charge?
No, there is no core charge for this service. You are welcome to keep your original, non-working module.
