Expert Insight: The Key is in the Programming
From the Mechanic’s Bench: We’ve seen countless GM workhorses from this era come through the shop with perplexing electrical faults. The root cause is almost always a failing BCM. The critical mistake some people make is installing a used module without proper programming. It simply won’t work. Each BCM must be coded to the vehicle’s specific VIN and options package. Our service handles that critical step for you, ensuring the new module integrates perfectly, just like the original, and provides a lasting repair.
Important Post-Installation Information
To ensure a smooth and successful installation, please be aware of these potential procedures. While not always necessary, they are common for BCM replacements on these models.
- Airbag System Sync: If the airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. This is the primary benefit of our service. We pre-program the module to the VIN you provide during checkout. It will arrive ready to be installed in your vehicle, with no additional programming required.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the BCM correctly for your specific truck or SUV.
Is this part difficult to install?
The BCM is typically located under the driver’s side or center of the dashboard. For someone with basic mechanical skills and tools, it is a manageable job. We always recommend disconnecting the battery before starting any electrical work.
Will this fix my security system issues?
Yes, a failing BCM is one of the most common causes of security system malfunctions, including the ‘Security’ light staying on or the engine being disabled. This programmed 1999-2000 Sierra 2500 BCM 16257125 is designed to resolve those communication faults.
What happens if my airbag light is on after I install it?
This is a normal possibility. It simply means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A qualified technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to turn off the light.

This BCM is a direct replacement for a wide range of part numbers, including: 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, and 09366801.
