This genuine OEM-quality BCM, part number 15926094, is the definitive solution for restoring your vehicle’s electronic systems to perfect working order. As the central command for your vehicle’s body electronics, a healthy BCM is crucial for everyday operation and safety.
This module arrives expertly pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and programming fees. It’s a true plug-and-play repair that gets you back on the road quickly. By installing this BCM, you’re not just fixing a symptom; you’re addressing the root cause of widespread electrical issues that can plague vehicles like the Chevrolet Silverado, GMC Sierra, Tahoe, and Yukon.
Symptoms of a Failing GM Body Control Module
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors that work intermittently or not at all.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or temperature controls that don’t respond.
- ✔ An illuminated airbag warning light, often with a DTC B1001 code.
- ✔ Vehicle security system malfunctions, leading to no-start conditions or false alarms.
- ✔ Unexplained battery drain while the vehicle is off.
- ✔ Communication errors with other vehicle modules, resulting in various warning lights on the dash.
Why Choose Our Pre-Programmed Sierra 1500 Body Control Module?
This isn’t just a replacement part; it’s a comprehensive repair solution. We load the latest GM software and your vehicle’s VIN onto the module before it ships. This ensures that it communicates flawlessly with your truck’s other electronic systems, like the Engine Control Module (ECM) and Supplemental Inflatable Restraint (SIR) module, right out of the box. This process restores factory functionality and resolves common Diagnostic Trouble Codes (DTCs) without any additional setup required for most functions.
Installation is straightforward for any DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the negative battery terminal, unplug the old module, plug in the new one, and reconnect the battery. While the process is simple, it’s important to note that in some cases, particularly if you have an active airbag light, a post-installation procedure using a professional scan tool may be necessary to sync the new BCM with the airbag system (SDM). We also recommend checking for any grounding issues during the replacement, as a poor ground can cause recurring electrical problems.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like your lights, power windows, door locks, wipers, security system, and climate controls.
Is this part difficult to install?
No, installation is typically very simple and takes less than 15 minutes. It involves unplugging the old module located under the steering column and plugging in the new one. No special tools are required for the physical replacement.
Do I need to go to the dealership after installing this part?
No. This BCM is pre-programmed to your vehicle’s VIN, so it’s ready for installation right out of the box. This saves you the time and expense of a dealership visit for programming.
What if my airbag light is still on after installation?
If the airbag light remains on, it means the new BCM needs to be synchronized with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with an advanced diagnostic tool.
