Restore Your Truck’s Electrical System to Perfect Health
Are you dealing with frustrating and unpredictable electrical problems in your GM truck or SUV? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or an engine that refuses to start can all point to one culprit: a failing Body Control Module (BCM).

Expert Insight: Why Do GMT800 BCMs Fail?
As a technician who has worked on countless of these trucks, I’ve seen BCM failures stem from a few common causes. Over two decades, simple heat cycles and vibrations can cause internal solder joints on the circuit board to crack. However, a primary culprit is often moisture intrusion. The windshield seals on these 2001-era GM trucks can degrade over time, allowing water to drip down the A-pillar and directly onto the BCM, which is located on the driver’s side dash. This leads to corrosion and short circuits. When you install your new module, it’s a great time to check for any signs of water leaks to protect your investment for the long haul. A proper 2001 Sierra 1500 BCM replacement isn’t just about the part; it’s about ensuring a lasting repair.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. The main benefit of our service is that we program the BCM for you before we ship it. Simply provide us with your vehicle’s VIN during or after checkout, and it will arrive ready to install, saving you a costly trip to the dealership.
How difficult is the installation?
The BCM is typically located under the driver’s side of the dashboard. For someone with basic mechanical skills and tools, it’s a manageable job that usually takes less than an hour. You will need to disconnect the battery, remove a few dash panels for access, and then unplug the electrical connectors from the old BCM and swap in the new one. The most critical part of a successful 2001 Sierra 1500 BCM replacement is ensuring the battery is disconnected before you begin.
What happens after I place my order?
After you purchase the BCM, you will need to send us your vehicle’s 17-digit VIN. We cannot program or ship the module without it. Once we receive your VIN, we will program the BCM with the latest GM software specific to your truck and ship it out to you promptly.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synced with the airbag control module (SDM). If the airbag warning light comes on, a procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a mechanic with a professional-grade scan tool. This is a quick procedure that resolves the light.
Will this fix the ‘Security’ light and no-start issue?
Yes, in the vast majority of cases. The BCM is a key part of the PassLock vehicle anti-theft system on these trucks. A failing BCM is a very common cause of an illuminated ‘Security’ light and the resulting no-start condition. This programmed module is designed to resolve that issue.
