Is Your GM Truck or SUV Experiencing Bizarre Electrical Problems?
If your 2002 Chevrolet Tahoe, Silverado, Suburban, or other compatible GM vehicle is suffering from strange electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it starts to fail, you can experience a frustrating array of problems that seem to have no rhyme or reason, from flickering lights to a vehicle that won’t start.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security or anti-theft light is illuminated on the dash.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ The horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss with the BCM (U-codes).

Installation and Post-Install Requirements
While this module is designed for a straightforward installation, some vehicles may require additional steps after the part is installed to ensure full functionality. Please be aware of the following potential procedures:
- 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: On some models, a brake pedal position sensor recalibration may be necessary for correct 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.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and the instrument cluster.
Is this BCM ready to install out of the box?
Yes! This BCM is programmed to your vehicle’s VIN before it ships. This ensures it has the correct software and settings for your specific options, making installation much simpler than with a non-programmed module.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship your order until we receive this information to program the module correctly.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after I install it?
This can happen because the new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool to resolve this.
Will this fit my vehicle?
This module fits a wide range of 2002-2005 GM trucks, vans, and SUVs including the Tahoe, Suburban, Silverado, Sierra, Yukon, Escalade, Astro, Safari, and S10/Blazer. Please verify your part number and check the detailed fitment list on this page to confirm compatibility.
