Are you battling frustrating electrical gremlins in your truck? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or intermittent starting issues can often be traced back to a single, vital component: the Body Control Module (BCM). This module acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and unpredictable problems. Restore order and reliability to your vehicle with our pre-programmed Body Control Module, specifically prepared for your 1999-2000 Isuzu Hombre and a wide range of compatible GM trucks and SUVs.
The Central Command for Your Vehicle’s Comfort and Security
The BCM is an essential computer that manages a vast array of non-engine-related functions. Think of it as the traffic controller for features you use every day, such as interior and exterior lighting, power door locks, keyless entry, the anti-theft system, and even the horn. When it begins to fail, communication between these systems breaks down, leading to the erratic behavior you’re likely experiencing. Simply swapping a BCM from another vehicle won’t work, as these modules are coded specifically to the vehicle’s unique Vehicle Identification Number (VIN) and its specific options.
Solving Electrical Chaos with a Pre-Programmed 1999-2000 Isuzu Hombre BCM
Our solution eliminates the guesswork and the expensive trip to a dealership. We provide a high-quality replacement BCM that is professionally programmed to your vehicle’s exact VIN before it ships. This means the module arrives at your door ready for installation, loaded with the latest software updates from GM to ensure optimal performance and reliability. This plug-and-play approach gets your truck back to full functionality quickly and efficiently, restoring the features you depend on.
Symptoms This BCM Will Correct
- ✔ Erratic or non-functional interior or exterior lights (headlights, dome lights, dash lights).
- ✔ Power door locks or windows operating intermittently or not at all.
- ✔ The security system or anti-theft light staying on, preventing the vehicle from starting.
- ✔ Keyless entry remote not working despite having a good battery.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Unexplained battery drain when the vehicle is turned off.
- ✔ Warning lights on the dashboard related to systems controlled by the BCM.
Installation and Post-Install Considerations
Physically installing the BCM is typically straightforward. It is often located under the dashboard on the driver’s or passenger’s side. The process involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors from the old module to swap in the new one. However, after installation, some vehicles may require additional synchronization procedures.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after the BCM is replaced. This is because the BCM needs to be electronically synced with the Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary on certain models to ensure correct brake light operation and to prevent issues with the traction control system.
We make the process simple: after your purchase, provide us with your VIN, and we handle all the programming. You receive a part that is ready to go, minimizing vehicle downtime. Best of all, there is no core charge, so you can keep your original module.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, security systems, and interior chimes.
How does the VIN programming service work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to flash the BCM with the correct software and vehicle-specific settings from GM’s database before we ship it to you.
Is this BCM difficult to install?
The physical installation is generally simple for someone with basic mechanical skills, as it’s a plug-and-play part. However, some vehicles may require post-installation electronic procedures, like an airbag system sync, which needs a professional diagnostic tool.
What if my airbag light is on after I install the new BCM?
If the airbag light comes on, it means the BCM needs to be synced with the airbag system’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to turn off the light.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module without any additional fees.
Will this fit my Chevy S10 or GMC Sierra?
Yes, this BCM is compatible with a wide range of GM trucks and SUVs from the 1998-2000 era, including the S10, Sonoma, Blazer, Jimmy, Silverado, and Sierra, as long as the original part number matches one of those listed.
