Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2002 GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or a persistent security light are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement BCM, part number 19208544, is the definitive solution to restore your vehicle’s proper operation and reliability.
This isn’t just a part in a box. To make your repair as simple as possible, we program the module to your vehicle’s specific VIN before it ships. This critical step ensures compatibility and integrates the BCM with your truck’s existing systems, saving you a costly trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security light is illuminated on the dashboard, and you may experience no-start conditions.
- ✔ Instrument cluster gauges behaving erratically or not working.
- ✔ Radio, HVAC, or climate control systems malfunctioning.
- ✔ False warnings or messages appearing on the driver information center.
Installation and Post-Install Procedures
This BCM is located under the steering column for easy access. While the physical installation is straightforward, please be aware of potential post-installation steps. Because this module communicates with other critical systems, some vehicles may require a ‘re-sync’ procedure to ensure all components work together correctly.
- Airbag System Sync: If the airbag warning light (SRS light) is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional 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 necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
