Restore Full Functionality to Your Vehicle’s Electronics
Is your Chevrolet, GMC, or Cadillac experiencing a host of bizarre and frustrating electrical problems? Issues like malfunctioning power windows, erratic door locks, flickering interior lights, or false security alerts are often hallmark signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of seemingly unrelated issues. This programmed Body Control Module, compatible with part numbers 13594768, 13594692, and others, is the definitive solution to restore your vehicle’s electronic systems to factory-perfect operation.
From the Diagnostic Bay
We recently had a 2015 GMC Sierra in the shop with a classic BCM failure. The owner was frustrated because his truck’s battery would be completely dead every morning. He had already replaced the battery and alternator to no avail. After a thorough diagnosis, we traced a significant parasitic draw back to the BCM. The module was failing to enter its ‘sleep’ mode, keeping other systems active overnight and draining the battery. Instead of a costly trip to the dealer for a new module and programming, we provided a cloned BCM. The installation was a simple swap, the parasitic draw was gone, and the customer was back on the road without the daily headache of a dead battery.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, not turning on, or flickering randomly.
- ✔ The security system engaging without reason or the key fob not working correctly.
- ✔ Unexplained parasitic battery drain leading to a dead battery.
- ✔ False warnings on the instrument cluster (e.g., ‘Service Theft Deterrent System’).
- ✔ Horn honking unexpectedly or wipers activating on their own.
- ✔ HVAC (heating and air conditioning) controls not responding.
Understanding Your 2014-2017 Caprice BCM Solution
Replacing a BCM isn’t typically a simple swap. A new module from the dealership requires expensive, vehicle-specific programming to communicate with your car’s other electronic systems. Our unique cloning service completely eliminates this step. You simply send us your original BCM, and we perform a full data transfer to this replacement unit. We copy the VIN, mileage, key data, and specific option configurations. The module you receive back will be 100% plug-and-play, ready for immediate installation without any need for additional programming. It’s the most efficient and cost-effective way to solve your vehicle’s electrical issues.
Installation and Post-Install Considerations
Installation is straightforward: locate your old BCM (typically under the steering column or in the driver’s side dash area), disconnect the battery, unplug the electrical connectors, and swap in the replacement module. While our programming makes this a plug-and-play process, some GM vehicles may require one or two simple relearn procedures after installation:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates a sync mismatch between the new BCM and the airbag’s SDM. A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to resolve this. This is only required if the light is on.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor recalibration might be necessary. This is also performed with a capable diagnostic tool.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Guaranteed Compatibility
This module is a direct replacement for a wide range of GM vehicles and is guaranteed to be compatible with the following part numbers: 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769. It fits numerous models including the Chevy Caprice, SS, Corvette, Impala, Silverado, Suburban, Tahoe; GMC Sierra, Yukon; Cadillac ATS, CTS, XTS, and Escalade from approximately 2014 to 2019. Please verify your part number and check the fitment list to ensure this is the correct part for your vehicle.
Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of transferring all the vehicle-specific data—like the VIN, security information, and optional feature settings—from your original BCM to a replacement unit. This makes the replacement module a plug-and-play part, avoiding the need for expensive dealership programming.
How does the process work after I place my order?
After you complete your purchase, we will contact you with detailed instructions on how to ship your original BCM to our facility. Once we receive it, we will perform the data transfer service and ship the newly programmed replacement BCM back to you, typically within 1-2 business days.
Is this BCM truly plug-and-play?
Yes, in over 99% of cases. Because we clone your original data, the vehicle recognizes the replacement module as its own. In rare instances, as noted above, a simple relearn procedure like an airbag sync or brake pedal position relearn may be required.
What if my original BCM is completely dead or not communicating?
Even if your BCM is severely damaged (e.g., by water or a short circuit), we can often still extract the necessary data directly from its memory chips. Please contact us before ordering if you suspect your module is unreadable so we can discuss the options.
Do I need to return my old BCM as a core?
No, there is no core charge for this part. You will need to ship your original BCM to us for the cloning service, but we do not require you to leave it with us.
