End Your Truck’s Electrical Headaches for Good
Are strange electrical problems making your reliable GM truck feel unpredictable? A failing Body Control Module (BCM) is often the culprit behind frustrating issues like erratic lights, malfunctioning power accessories, or a security system that leaves you stranded. This professionally programmed BCM is the direct-fit, definitive solution to restore your vehicle’s core electronic functions and get you back on the road with confidence.
Common Symptoms & Your Direct-Fit Solution
If you’re experiencing any of the following, a faulty BCM is the likely cause:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior dome lights or exterior lamps staying on or failing to turn on.
- The security or anti-theft system preventing the engine from starting.
- Erratic behavior from the instrument panel gauges or warning lights.
- Diagnostic Trouble Codes (DTCs) related to lost communication, such as U1000.
This isn’t just a replacement part; it’s a fully integrated solution. We flash this Pre-Programmed 1999-2000 Sierra 1500 BCM with the latest GM software using your vehicle’s specific VIN.

A Technician’s Note on BCM Replacement
As a technician with over 20 years of experience, I’ve seen countless DIY jobs get stalled at the final step: programming. Many people buy a used BCM from a salvage yard only to find it won’t work because it’s locked to another vehicle’s VIN, creating a ‘bricked’ part and a massive headache. Our process eliminates that risk entirely. By programming the module to your specific VIN before it ships, we handle the most complex part of the job for you. This ensures that when you install our Pre-Programmed 1999-2000 Sierra 1500 BCM, it communicates correctly with your truck’s other computers, like the PCM and SDM (airbag module), right out of the box.
Important Post-Installation Information
While this module is programmed for plug-and-play functionality, certain vehicle systems may require a relearn or sync procedure after installation. Please be aware of the following possibilities:
- 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 module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is essential for the part to function correctly in your vehicle.
Is this BCM difficult to install?
For most of the listed GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard. It typically involves removing a few dash panels for access and disconnecting several electrical connectors. While it’s a manageable job for a confident DIYer, we always recommend consulting a service manual for the exact procedure for your model. The most difficult part, the programming, is already done for you.
Will this Pre-Programmed 1999-2000 Sierra 1500 BCM fix my security/anti-theft issue?
In most cases, yes. The BCM is a critical part of the GM Passlock and VATS security systems. A failing module is a very common cause of no-start conditions related to the security light. This pre-programmed module is designed to restore that functionality.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s existing airbag control module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. It’s a quick procedure for a shop with the right equipment.
Do I need to send my old BCM back?
No. This BCM is sold without a core charge. You can keep your original module without any penalty or extra fees.
