Is Your GM Truck or SUV Experiencing Strange Electrical Problems?
If your 2002 Chevrolet Suburban 1500, Silverado, Tahoe, or another compatible GM vehicle is acting possessed, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central computer for your vehicle’s body electronics, managing everything from power windows and locks to the interior lights, security system, and horn. When it starts to fail, it can cause a cascade of frustrating and unpredictable issues that can be difficult to diagnose.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security or anti-theft system light is illuminated, preventing the vehicle from starting.
- ✔ Horn honking randomly or failing to work when needed.
- ✔ The radio or climate control display behaves erratically.
- ✔ False warning messages on the instrument cluster, like “Service Vehicle Soon.”
- ✔ Inconsistent A/C compressor or blower fan operation.

Important Post-Installation Information
While this BCM is designed for a straightforward installation, some vehicle systems may require a ‘handshake’ with the new module. In some cases, you may need a professional scan tool to perform simple relearn procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary on certain models to ensure correct brake light and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does the BCM actually do on my truck?
The Body Control Module acts as the brain for your truck’s non-engine related electronics. It controls the power windows, locks, lights, security system, horn, wipers, and more, ensuring all these comfort and convenience features work together properly.
Do I need to take this part to a dealer for programming?
No! This is the key benefit of our service. We program the BCM with the latest GM software using the VIN you provide before we ship it. This makes the installation process much simpler and saves you from expensive dealership programming fees.
How do I find my original part number to confirm a match?
Your BCM is typically located under the steering column or in the center dash area. The part number is printed on a white sticker on the module’s case. This module replaces part numbers 15063578, 15081796, 15095334, and others listed in the description.
What if my airbag light turns on after I install the new BCM?
This is not a defect. It simply means the new BCM needs to be electronically introduced to your vehicle’s airbag system (SDM). A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is this a difficult part to replace myself?
For someone with basic mechanical skills, the physical replacement is generally straightforward. It involves removing a few dash panels to access the module, unplugging the electrical connectors, and swapping the unit. The most important part is that our pre-programming saves you the most complex step.
