Are you battling frustrating electrical gremlins in your 2002 GM truck or SUV? Issues like erratic power windows, door locks that have a mind of their own, a security light that won’t turn off, or even a no-start condition can often be traced back to a single component: the Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and seemingly unrelated problems. Stop chasing symptoms and replace the root cause with our reliable, VIN-programmed BCM.
This is a direct-fit replacement for part number 15095334 and several other interchangeable part numbers. We take the guesswork and hassle out of the installation process. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will program the module with the latest GM software specific to your vehicle’s configuration. This ensures a seamless, plug-and-play installation, getting your vehicle’s essential features working correctly again without a costly trip to the dealership.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security or anti-theft light is illuminated, preventing the engine from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ The radio or other interior accessories turning on and off randomly.
- ✔ Key fob not responding or working unreliably.
Installation for Your 2002 Avalanche Body Control Module
This module is designed for a straightforward installation. On most compatible trucks and SUVs like the 2002 Avalanche, Silverado, and Sierra, the BCM is located under the driver’s side of the dashboard, near the steering column. Once installed, your vehicle’s core functions will be restored. However, please be aware of potential post-installation procedures that may be required for your specific model.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Compatible Part Numbers:
This module is a direct replacement for part numbers 15063578, 15081796, 15095334, 19208537, DKAK, and DPNU, ensuring wide compatibility across many GM models.
