Restore Your Vehicle’s Electrical Functions with a VIN-Programmed BCM
Are you chasing electrical gremlins in your GM vehicle? Flickering lights, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s comfort and convenience features. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. Instead of spending a fortune on diagnostic time and dealership programming, get a reliable, direct-fit solution.
This Body Control Module, part number 95151084, is the definitive fix for your vehicle’s electronic woes. We take the guesswork and hassle out of the repair by programming the module to your vehicle’s specific VIN before we ship it. This ensures that it communicates perfectly with your vehicle’s existing systems right out of the box. All you need to do is provide your VIN at checkout, and we’ll handle the complex programming with the latest GM software updates. This is the most efficient way to get your truck or van back to 100% functionality.
From the Diagnostic Bay
A customer brought in a 2011 Express 2500 work van that was becoming a real headache for his business. The driver reported the interior lights would stay on, draining the battery overnight, and the power door locks worked intermittently. He had already replaced the battery twice. On the bench, I saw no-communication codes with the BCM on my scan tool. These vans are workhorses, and their BCMs are located in the center dash area, where they can be susceptible to moisture from spills or a leaky windshield seal over time. We installed one of our pre-programmed BCMs, performed the quick post-install procedures, and the van’s electrical systems were stable and reliable again. It’s a common failure, but with a properly programmed module, it’s a straightforward fix.
Is Your Vehicle Showing These Classic BCM Failure Signs?
- ✔ Erratic or non-functional power windows and door locks.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security or anti-theft system light is illuminated, preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication error codes with the BCM (U-codes) stored in other modules.
A Straightforward Guide to Your BCM Replacement
Installing your new 2008-2012 Express 2500 BCM is a manageable job for a DIY enthusiast or a quick task for any professional. While the exact location varies by model, the general process is similar.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most Express/Savana vans, the BCM is located in the center dash area. On other models like the Impala or Acadia, it’s typically on the left side of the dash or under the steering column. A quick search for your specific model will confirm the location.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the BCM. Use a trim removal tool to avoid scratching or breaking clips.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Perform Post-Install Procedures: Reconnect the battery. You will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the airbag light. Some vehicles may also require a Brake Pedal Position Sensor calibration.
Important Post-Installation Requirements
To ensure full functionality and safety after installing your new BCM, a couple of steps are required. These procedures sync the new module with your vehicle’s critical safety systems. You will need a bi-directional scan tool or to visit a shop that has one.
- Airbag System Reset: You must perform the ‘Setup SDM Primary Key in BCM’ procedure. This step is essential to re-establish communication between the BCM and the airbag system (SDM), which will turn off the airbag warning light.
- Brake Pedal Calibration: On some models, the Brake Pedal Position (BPP) Sensor needs to be recalibrated. This ensures the brake lights and stability control systems function correctly.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you before shipment. Just provide your vehicle’s 17-digit VIN during checkout, and the module will arrive ready for installation and final setup procedures.
What tools are required for the installation?
You’ll need basic hand tools like a socket set and screwdrivers to remove trim panels and the old BCM. A plastic trim removal tool is highly recommended to prevent damage. A bi-directional scan tool is required for the post-installation airbag and brake sensor procedures.
Will this fix my ‘Service Theft System’ message?
In many cases, yes. The BCM is a critical part of the vehicle’s anti-theft (Pass-Key/Pass-Lock) system. A faulty BCM is a very common cause of this warning and the associated no-start condition.
Is this a brand new part?
This is a high-quality, tested, and verified original equipment part that has been expertly programmed with the latest software for your vehicle. It is guaranteed to restore your vehicle’s function.
What happens if I don’t do the airbag (SDM) reset?
The airbag warning light will remain on, and more importantly, the airbag system may not function correctly in the event of a collision. This is a critical safety step that must not be skipped.
