Restore Your Truck’s Electrical System to Perfect Health
Are you battling frustrating electrical gremlins in your Isuzu Hombre or GM truck?

Don’t let these unpredictable issues compromise your vehicle’s reliability. This professionally programmed BCM is the definitive, hassle-free solution to restore full functionality and get your truck back to dependable working order.

Expert Insight: The Junkyard Gamble vs. A Sure Bet
Many owners are tempted to grab a used BCM from a salvage yard to save a few dollars. This is almost always a mistake. A used module is a black box—you don’t know its history, and it’s programmed for the donor vehicle, not yours. It will not work correctly without being reprogrammed by a dealer, which can cost hundreds of dollars and often leads to compatibility headaches. Our Programmed 1999-2000 Isuzu Hombre BCM eliminates that gamble entirely. You receive a tested module, loaded with fresh software, and perfectly matched to your truck’s configuration. It’s the smart, reliable repair that gets the job done right the first time.
Frequently Asked Questions
What exactly does the BCM control on my truck?
The Body Control Module acts as the central hub for your vehicle’s body electronics. It manages non-engine related functions like the power windows, door locks, interior and exterior lighting, alarm system, and often communicates with the radio and climate controls. When it fails, these systems can behave erratically.
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 a critical step in the process.
Is any other programming required after I install it?
In most cases, no. The unit is shipped ready to install. However, on some models, if the airbag light appears, a simple “Setup SDM Primary Key in BCM” procedure may be needed by a technician with a capable scan tool. Additionally, a Brake Pedal Position Relearn might be necessary. These are sync procedures, not full programming.
Do I have to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, making the process simpler and faster for you.
My original part number is slightly different. Will this still work?
Yes, this BCM is a direct replacement for all part numbers listed in the description, including 16257125, 19153625, and others. As long as your vehicle is listed in the fitment chart, this module, once programmed to your VIN, will function correctly.
Will this fix my truck’s security or anti-theft issue?
A failing BCM is a very common cause of security system problems (like GM’s Passlock system) in these trucks. While we can’t diagnose your vehicle remotely, replacing a faulty BCM with this Programmed 1999-2000 Isuzu Hombre BCM is a very effective solution for these specific issues.
