Restore Full Electronic Functionality to Your GM Vehicle
Is your 2014 Sierra, Silverado, or other compatible GM vehicle suffering from bizarre and unpredictable electrical issues? The Body Control Module (BCM) is the central command center for your vehicle’s body electronics, and when it begins to fail, it can cause a cascade of frustrating problems. This replacement BCM, part number 13594768, is offered with a professional programming service that makes replacement straightforward and eliminates the need for expensive dealership programming.
From the Diagnostic Bay
We recently had a 2014 Sierra 1500 in the shop with a list of symptoms that sounded like a ghost was in the machine. The dome lights would flicker randomly, the radio would turn on by itself overnight draining the battery, and the driver’s side power window would only work intermittently. The owner had already replaced the battery and checked all the fuses. After ruling out wiring issues, we hooked up our scope to the BCM’s data network and saw corrupted signal packets. The BCM itself was failing internally, sending phantom commands throughout the truck. By providing a replacement BCM with the original’s data cloned onto it, we were able to solve every single electrical gremlin in one go. The customer was thrilled to have his truck back to normal without a massive dealership bill.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The anti-theft or security system acting erratically or preventing the engine from starting.
- ✔ Key fobs that stop working or only work sporadically.
- ✔ False warning messages appearing on the instrument cluster (e.g., “Service StabiliTrak,” “Service Airbag”).
- ✔ Unresponsive climate controls or radio functions.
- ✔ A parasitic battery drain that kills your battery overnight.
Understanding Your 2014 Sierra BCM Solution
This isn’t just a part; it’s a complete service designed to get you back on the road quickly. The BCM in modern vehicles is tied to the specific VIN, security system, and options of your truck. Simply installing a used module from another vehicle will not work. Our professional cloning service is the key. You send us your original, faulty BCM. We then extract the unique, vehicle-specific data and flash it directly onto this fully tested replacement unit. The module you receive back is a true plug-and-play component, programmed specifically for your vehicle’s VIN and options. This process ensures all existing keys and remotes will work perfectly upon installation.
Installation and Post-Install Considerations
Physically installing the BCM is typically straightforward, as it’s located under the steering column on most compatible trucks and SUVs. Once installed, the vehicle will start and run as normal. However, in some cases, additional synchronization procedures may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor relearn might be necessary. This can also be performed with a compatible diagnostic tool.
We provide this service for a wide range of GM vehicles. Please check the fitment list to confirm this part is correct for your specific make, model, and year. This module is a direct replacement for part numbers 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769.
Frequently Asked Questions
What is a BCM cloning service?
Cloning is the process of reading all the critical, vehicle-specific data (like VIN, mileage, key information, and security settings) from your original BCM and writing it onto the replacement module. This makes the new module an exact electronic match to your old one, ensuring a plug-and-play installation.
Why do I have to send my original BCM to you?
Your original BCM holds the unique digital fingerprint for your vehicle. We need it to extract this data. Without it, the replacement module would not be able to communicate with the other computers in your vehicle, and it would not start or function correctly.
Is this solution truly plug-and-play?
Yes, for all engine and security functions. Because we clone your data, the vehicle will start and run without any additional security programming. In some cases, as noted above, minor sync procedures for systems like the airbag or brake sensor may be needed, which require a professional scan tool.
How long does the programming service take?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. We will provide you with a return tracking number as soon as it ships.
What happens if the airbag light is on after I install it?
This is a known possibility and simply means the new BCM needs to be electronically introduced to the airbag system’s Sensing and Diagnostic Module (SDM). A repair shop with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fit vehicles other than a 2014 Sierra?
Absolutely. This BCM fits a wide variety of GM cars, trucks, and SUVs from roughly 2014-2019, including the Silverado, Tahoe, Suburban, Corvette, CTS, Impala, and Escalade. Please verify your original part number matches one of the numbers listed in the description.
