Expert Insight: Why BCMs Fail & The Importance of Software
Over two decades, the original BCMs in these hardworking trucks endure countless heat cycles, vibrations, and voltage fluctuations. Internal solder joints can crack and electronic components can degrade, leading to the bizarre electrical issues you’re seeing. Our process involves more than just a replacement; we ensure each 1998-2000 GM BCM Body Control Module is loaded with the newest stable software from GM. This updated programming resolves many of the original bugs and electronic conflicts that contributed to the initial failure, providing a more robust and reliable long-term fix than simply installing another old, un-updated unit.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your truck.
Is this BCM truly ‘plug and play’?
Yes, for the vast majority of vehicles, it is. Because we program it to your VIN, it’s ready for installation right out of the box. However, as with any complex electronic repair, some vehicles may require a simple post-installation procedure, such as an airbag system sync, if a warning light appears. This is detailed in the product information.
What if the airbag light comes on after installation?
This can occasionally happen as the new BCM syncs with your vehicle’s other systems. A professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified mechanic and will sync the systems to turn off the light.
Will this fix my exact electrical problem?
This 1998-2000 GM BCM Body Control Module is the solution for a wide range of common electrical failures. While it resolves the vast majority of issues related to power accessories, security, and interior electronics, proper vehicle diagnosis is always recommended. This part will fix problems originating from a faulty BCM.
Do I need to return my old BCM?
No. This purchase comes with no core charge. You are free to keep or dispose of your old module as you see fit, saving you the time and expense of return shipping.
