Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If your 2014 Sierra Denali 1500, Silverado, Tahoe, or another compatible GM vehicle is experiencing bizarre electrical issues, a failing Body Control Module (BCM) is often the culprit. The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights, security system, and even communication between other critical modules. When it fails, it can create a cascade of frustrating and seemingly unrelated problems that can be difficult to diagnose.
Expert Pro Tip: Before condemning your BCM, always perform a full vehicle battery and charging system test. A weak battery or a failing alternator can cause low voltage conditions that mimic BCM failure. Also, check the main power and ground connections to the BCM for any signs of corrosion or looseness. Sometimes, the simplest fix is the right one.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system randomly activating or preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Inaccurate gauge readings or warning lights on the dashboard.
- ✔ Communication errors with diagnostic scan tools (U-codes).
- ✔ A no-start condition where the engine cranks but won’t fire up due to a security fault.

Installation & Post-Install Notes
The BCM on most compatible trucks like the 2014 Sierra and Silverado is located under the driver’s side of the dashboard, near the steering column. While installation is plug-and-play, some vehicles may require minor post-installation procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is because the BCM and the SDM (Sensing and Diagnostic Module) need to re-establish their security handshake. A professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure to resolve this.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper brake light operation and to prevent issues with the traction control system. This can also be performed with a compatible diagnostic tool.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How does this programming service work?
You send us your original BCM. We then use specialized equipment to extract the unique data from your module and transfer it to the replacement unit. This ‘cloning’ process makes the replacement BCM a plug-and-play part for your specific vehicle.
Will I need to go to the dealership for programming?
No. Our service completely eliminates the need for dealership programming. Because we clone your original data, your vehicle will accept the new module without any additional setup.
Where is the BCM located on my 2014 Sierra?
On the 2014 GMC Sierra and Chevrolet Silverado, the BCM is typically located under the driver’s side dashboard, to the left of the steering column.
What happens if the airbag light is on after installation?
If the airbag light is on, it means the BCM needs to be electronically synced with the airbag module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. It’s a quick procedure for any well-equipped auto shop.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary security and key information is stored within the data of your original BCM, which we will transfer to the replacement.
