Are you battling frustrating electrical issues in your GM truck, van, or SUV? A faulty Body Control Module (BCM) is often the culprit behind problems like malfunctioning power windows, erratic lights, and security system failures. This replacement BCM is the definitive solution, arriving pre-programmed with the latest GM software specifically for your vehicle’s VIN. This eliminates the need for expensive dealership programming, making your repair simpler and more affordable.
Diagnosing and Solving with a 2002 Suburban BCM
The BCM acts as the central hub for your vehicle’s body electronics. When it begins to fail, it can cause a cascade of confusing symptoms that seem unrelated. By replacing your old module with this pre-configured unit, you are restoring the core of that system. We handle the complex part—the programming—so you can focus on the straightforward physical installation.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior dome lights or exterior lamps staying on or not turning on at all.
- ✔ The security system acting up, preventing the vehicle from starting (Security light on).
- ✔ Horn honking randomly or not working when pressed.
- ✔ Instrument cluster warnings or messages appearing without cause.
- ✔ Radio or climate control systems behaving erratically.
This module is a direct fit for a wide range of GM vehicles and is compatible with multiple part numbers, including 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU. Simply provide your VIN during checkout, and we’ll ensure the module is a perfect match for your vehicle’s specific options and software requirements.
Installation Note: After installing the new BCM, some vehicles may require additional relearn procedures. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. A Brake Pedal Position relearn may also be necessary for proper brake light and traction control function. Best of all, there is no core charge, so you can keep your original module.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories such as power windows, locks, lights, security systems, and the horn. It’s the central command for most non-engine related electronics.
How do I provide my VIN for programming?
You can enter your vehicle’s 17-digit VIN in the notes section during checkout or simply reply to your order confirmation email with the information. We cannot ship the part until we have your VIN to program it.
Is this part difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. It’s usually located under the steering column or in the center dash. The key is that our pre-programming service removes the most difficult step, which is software configuration.
Will this fix my specific electrical problem?
This module is the solution for a very wide range of common electrical failures. If your vehicle is experiencing several of the symptoms listed, a failing BCM is the most likely cause. However, always ensure your vehicle has been properly diagnosed.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module without any extra fees.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A repair shop with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
