Are you tired of dealing with the frustrating and unpredictable electrical problems in your GM truck or SUV? One moment your power windows work, the next they don’t. The radio might shut off randomly, or you’re greeted by a dashboard of warning lights that make no sense.

Instead of spending a fortune at the dealership for diagnostics and programming, get the reliable, permanent fix right here.
This is a direct-fit replacement BCM for your 2012-2014 Silverado 2500 and a wide range of other GM vehicles. The best part? We handle the complicated part for you. Simply provide your vehicle’s VIN at checkout, and our technicians will program the module with the latest GM software specific to your truck. It arrives at your door ready for a straightforward installation, eliminating the need for expensive scan tools or a trip to the dealer. This is the most efficient way to restore your vehicle’s electronics to perfect working order.
From the Diagnostic Bay: The Case of the Phantom Battery Drain
A customer brought in his 2013 Sierra 2500, completely frustrated. He’d replaced the battery twice in six months, but it kept dying overnight. He had flickering interior lights and the remote key fob worked intermittently. He was convinced the truck was cursed. After ruling out the alternator and parasitic draws from accessories, I hooked up my diagnostic scanner. The BCM wasn’t allowing other modules to go to ‘sleep’ mode when the truck was off, causing a constant, slow drain. We swapped in a pre-programmed BCM like this one, and the problem vanished instantly. It’s a common failure I’ve seen dozens of times, and a new BCM is almost always the definitive fix.
Is Your Truck Plagued by These Electrical Gremlins?
A faulty BCM can cause a wide range of confusing symptoms. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The radio or infotainment system randomly shutting off or acting erratically.
- ✔ False warning messages on the driver information center (DIC).
- ✔ A security light that stays on, preventing the engine from starting.
- ✔ Communication error codes (U-codes) stored in the system, like U0140.
- ✔ Unexplained battery drain that leaves you with a dead battery.
Your Straightforward BCM Installation Guide
Replacing the BCM is a job most DIYers can handle in their own driveway. This module is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most of these GM trucks and SUVs, it’s found under the driver’s side dash. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical harnesses. You’ll hear a ‘click’ when they’re seated properly.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all functions: lights, windows, locks, radio, etc.
Important Post-Installation Steps
Because this BCM is pre-programmed, most functions will work immediately. However, depending on your vehicle’s specific configuration, a couple of simple relearn procedures may be needed to sync everything perfectly.
- ✔ Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- ✔ Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure the brake lights and traction control system function correctly. This can also be done with a capable scan tool.
Disclaimer: While these steps are straightforward, we always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the process.

Frequently Asked Questions
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is the computer that controls most of your vehicle’s non-engine related electronics. This includes power windows, locks, lights, wipers, the security system, and the radio. When it fails, you get strange electrical issues.
Do I really need to provide my VIN?
Yes, it’s essential. We use your VIN to load the correct software and settings for your vehicle’s specific options. This ensures it works correctly right out of the box and saves you a trip to the dealership for programming.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
What if the part number on my old module is slightly different?
This module replaces several part numbers, including 22737275 and 22846364. As long as your vehicle is on our compatibility list, this BCM will work perfectly once programmed to your VIN.
What tools are required for installation?
Basic hand tools are usually all that’s needed, such as a socket set and a trim removal tool to access the module under the dashboard. No special programming tools are required on your end.
