Is Your 2014 Sierra Experiencing Strange Electrical Problems?
The Body Control Module, or BCM, is the central nervous system for your truck’s electronic accessories. It’s not part of the engine or transmission control; instead, it manages everything from your power windows and door locks to your interior lights, security system, and even the turn signals. When the BCM starts to fail, it can create a host of confusing and frustrating symptoms that seem unrelated. One moment your radio might act up, and the next, your dome light won’t turn off. This isn’t just an annoyance—a faulty BCM can affect vehicle security and safety systems.
Symptoms of a Failing Body Control Module
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, not working, or flickering erratically.
- ✔ The vehicle’s security system or alarm malfunctioning or engaging randomly.
- ✔ Inaccurate or non-working gauges on the instrument cluster.
- ✔ Key fob not being recognized or working intermittently.
- ✔ Communication error codes (U-codes) stored in the vehicle’s diagnostic system.
- ✔ Parasitic battery drain that kills the battery overnight.

Post-Installation Information
While our goal is a seamless plug-and-play experience, some modern vehicles may require minor electronic handshakes after a new module is installed. Please be aware of the following potential procedures:
- Airbag System Sync: If you see an airbag warning light after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is performed with a professional-grade scan tool and re-syncs the BCM with the airbag system.
- 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: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly is a BCM?
The Body Control Module (BCM) is a computer in your vehicle responsible for managing and controlling various electronic body functions. This includes power windows, locks, lights, wipers, the security system, and more. It acts as a central hub for these systems.
How does your cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Our technicians will then extract the critical data from your module and flash it onto the replacement unit. We then ship the programmed replacement back to you, ready for installation.
Why do I need to send you my original part?
Your original BCM contains the specific programming for your vehicle’s VIN, key data, and optional features. By transferring this data, we ensure the replacement module is a 100% plug-and-play match, avoiding the need for expensive and complicated dealer programming.
Is this BCM truly plug-and-play?
Yes, in over 99% of cases, the module is completely plug-and-play. In rare instances, as noted in the description, a simple relearn procedure like an airbag sync or brake pedal position relearn might be required, which can be done by most automotive shops.
How long does the entire process take?
We typically program and ship the replacement module within 1-2 business days of receiving your original BCM. The total turnaround time will depend on shipping times to and from our facility.
Will this fix a parasitic battery drain?
A faulty BCM is a very common cause of parasitic battery drain, as it can fail to let other modules ‘sleep’ when the vehicle is off. If your diagnostics have pointed to the BCM as the source of the drain, this replacement will resolve the issue.
