Restore Full Functionality to Your GM Truck or SUV
Is your 2002 Tahoe, Suburban, or Yukon plagued by strange and unpredictable electrical problems? A faulty Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, managing everything from your power windows and locks to your interior lighting and security system. When it fails, it can cause a cascade of frustrating issues that can be difficult to diagnose. This replacement BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system acting up or preventing the vehicle from starting (Security light on).
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Problems with the radio or climate control functions.
Installation and Post-Install Steps for your 2002 Tahoe BCM
This module is a direct-fit replacement for the original unit located under the steering column. Because we program it with the latest GM software using your vehicle’s VIN, you can avoid a costly trip to the dealership for programming. Simply provide your 17-digit VIN after purchase, and we’ll handle the rest. While the physical installation is simple, please be aware of a few potential post-installation procedures that may be required to ensure all systems communicate correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control performance.
This module is a reliable replacement for service numbers: 15063577, 15081857, 19208544, 15095335, DKAJ, and DPNW.
