Tired of Chasing Electrical Gremlins in Your GM Truck or Van?
As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable vehicle into a source of constant frustration. Are your dash lights flickering for no reason? Do your power windows and locks have a mind of their own? These aren’t separate problems; they’re classic symptoms of a BCM on its way out. The BCM is the electronic nerve center for your vehicle’s body functions, and when it fails, chaos ensues. This isn’t just an annoyance—it can affect safety systems and even leave you stranded.
Forget the dealership hassle and high costs. We offer a dependable, streamlined solution: a direct-fit Programmed GM BCM, part number 15167329. The biggest hurdle in replacing a BCM has always been the mandatory, expensive programming. We eliminate that step for you. Simply provide us with your vehicle’s VIN during checkout, and our experts will flash this module with the latest GM software specific to your truck or van. It arrives at your door ready for installation, saving you hundreds of dollars and significant downtime.
A Technician’s Notebook: The 2005 Silverado Ghost
A customer brought in his ’05 Silverado 2500, completely fed up. The radio would turn on and off, the dome light would stay on, and occasionally the security light would flash, preventing it from starting. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple communication loss codes with various modules. This pointed directly to the BCM. Instead of sending him to the dealer, we ordered a Programmed GM BCM. The physical swap took less than 30 minutes. After performing the necessary key relearn and SDM reset, every single issue was gone. The customer was thrilled to have his reliable work truck back without the dealership price tag.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system light is on, or the vehicle won’t start (anti-theft issue).
- ✔ False warnings on the instrument cluster (e.g., “Service Airbag”).
- ✔ Radio or climate control malfunctions.
- ✔ Communication errors when using a diagnostic scan tool.
A Straightforward Guide to Your BCM Installation
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the Old BCM: On most Silverado and Sierra pickups, you’ll find the BCM mounted under the driver’s side of the dashboard, near the steering column. For Express and Savana vans, it is typically located behind the center dash panel.
- Disconnect and Remove: Carefully unplug the electrical connectors from the module. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new Programmed GM BCM in the same location and securely reconnect all electrical harnesses.
- Reconnect Battery: Re-attach the negative battery terminal.
- CRITICAL Final Steps: After installation, two procedures are often required. First, perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the airbag light. Second, some vehicles may need a ‘Brake Pedal Position Sensor Calibration’ to ensure proper brake light and ABS function. If you are not equipped to perform these steps, a local repair shop can complete them for you.

Frequently Asked Questions About This BCM
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings your vehicle had when it left the factory. This ensures all your specific options (like power seats, keyless entry, etc.) work correctly right out of the box.
Is this a simple plug-and-play part?
The physical installation is plug-and-play. However, as noted, post-installation procedures like resetting the airbag module (SDM key setup) and potentially calibrating the brake pedal sensor are required with a proper diagnostic tool to ensure full system functionality and safety.
Will this fix my ‘Security’ light and no-start problem?
In many cases, yes. The BCM is a core part of the Passlock/Passkey anti-theft system. A failing BCM is a very common cause of these symptoms. This programmed module will restore that functionality, though a key relearn procedure may also be necessary.
Can I install this myself?
A confident DIYer can certainly handle the physical swap, which is straightforward. The key is having access to a bi-directional scan tool (or a mechanic who does) to perform the final setup procedures. This is not optional for restoring full vehicle function.
What if I have a different part number on my old BCM?
This module replaces several part numbers, including 15194169, 15747545, and more, as listed above. As long as your original part number is on our cross-reference list, this module will work perfectly once programmed for your vehicle.
