Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical problems in your 2002 GM vehicle? Issues like erratic power windows, a security light that won’t turn off, intermittent starting problems, or malfunctioning gauges are often signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement Body Control Module, part number 15095334, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 2002 Sierra 2500 towed in that was a real head-scratcher for the owner. The truck would randomly refuse to crank, the radio would cut out, and the power door locks had a mind of their own. The battery and alternator tested fine. After connecting our diagnostic tool, we saw multiple communication loss codes pointing to the BCM. Instead of a costly and time-consuming repair at the dealership, we installed one of our pre-programmed BCMs. The truck fired right up, and all the strange electrical gremlins were gone. It’s a common failure, but with the right part, it’s a straightforward fix.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ The security or anti-theft light stays illuminated, preventing the engine from starting.
- ✔ Intermittent no-crank or no-start conditions.
- ✔ Interior dome lights, headlights, or taillights not working correctly.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ False warning messages on the driver information center.
- ✔ Issues with the heating and A/C blower motor controls.

Our technicians will then program the BCM with the latest GM software specific to your truck or SUV. This ensures that when the part arrives, it’s ready for installation without the need for a specialized scan tool for setup. This is the most efficient way to replace your faulty 2002 Silverado BCM and get your vehicle back to perfect working order.
Important Post-Installation Information
While our BCMs are programmed for a straightforward installation, some vehicle systems may require a relearn procedure after the new module is connected. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional scan tool to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, security system, wipers, and instrument panel gauges.
Is this BCM difficult to install?
Installation is typically straightforward. The BCM is usually located under the steering column or in the center dash area. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. Since we pre-program the module, no special tools are needed for the initial setup.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information.
What if my airbag light is on after I install the new BCM?
This is not uncommon. It means the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). A qualified mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this part fit my 2002 GMC Sierra or Chevy Tahoe?
Yes, this BCM fits a wide variety of 2002 GM models including the Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, and more. Please check the detailed fitment list and match your original part number to confirm.
