Are you battling frustrating electrical gremlins in your 2002 GM truck or SUV? Flickering lights, malfunctioning power windows, a persistent security light, or a vehicle that refuses to start are all 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 pre-programmed BCM is the definitive solution to restore your vehicle’s functionality and peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle out of the repair by programming the module to your vehicle’s specific VIN before it ships. This means you get a BCM loaded with the latest software updates from GM, ensuring optimal performance and compatibility. Simply provide your VIN after purchase, and we’ll handle the complex programming, saving you a costly trip to the dealership.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic interior or exterior lighting behavior.
- ✔ The ‘SECURITY’ or anti-theft light stays on, potentially causing a no-start condition.
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ Problems with the radio or climate control functions.
- ✔ False warning messages on the driver information center.

Installation & Post-Install Notes:
Installation is typically straightforward, as the BCM is located under the steering column or in the center dash area. After installation, please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after you install the BCM, 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 relearn may be required to ensure your brake lights and traction control system function correctly.
- No Core Charge: You are not required to return your old BCM. You can keep your original module, saving you time and return shipping costs.
