Is Your 2002 GM Truck Experiencing Strange Electrical Problems?
The Body Control Module, or BCM, is the central command center for your truck’s body electronics. When it begins to fail, it can cause a host of frustrating and seemingly unrelated issues. From flickering lights to malfunctioning power accessories, a faulty BCM can make your reliable truck feel unpredictable. This replacement Body Control Module, part number 19208537, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
From the Diagnostic Bay
We had a 2002 Sierra 2500 in the shop that was driving the owner crazy. The radio would turn off randomly, the dome light would stay on, and the power locks worked only when they wanted to. He had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The truck was back to normal in under an hour, saving the customer significant time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing intermittently.
- ✔ The radio or instrument cluster turning on and off by itself.
- ✔ False warning lights or messages appearing on the dashboard.
- ✔ Rapid battery drain when the vehicle is off.

Important Post-Installation Information
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ procedure after installation to recognize the new BCM. This is a normal part of the repair process.
- Airbag System Sync: If the airbag warning light is illuminated 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 might be necessary to ensure brake lights and traction control function as intended.
Please note: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for your specific vehicle.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it to you. This saves you a trip to the dealership and associated programming fees.
Where is the BCM located on my 2002 Silverado 2500?
On most 2002 GM full-size trucks like the Silverado, Sierra, Tahoe, and Yukon, the BCM is located under the driver’s side of the dashboard, near the steering column.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. However, as noted, some post-installation electronic relearn procedures may be required using a professional-grade scan tool.
What happens if my airbag light comes on after I install it?
This is a common occurrence. The new BCM needs to be electronically introduced to the airbag system (SDM). A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
