Restore Control Over Your Truck’s Electronics
Are you chasing down electrical gremlins in your 1998 Isuzu Hombre or GM S-Series truck? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s comfort and convenience features, a faulty BCM can make your daily drive a frustrating experience. This isn’t just an inconvenience; it can be a safety issue when exterior lights or security functions become unreliable.
This is a direct-fit replacement 1998 Isuzu Hombre BCM that arrives at your door fully programmed to your truck’s specific VIN. We handle the complex part—flashing the module with the latest GM software—so you don’t have to. Forget about expensive dealership visits for programming or towing fees. This module is designed to get your truck’s essential functions back online quickly and reliably.
A Technician’s Notebook
I remember a 1998 S10 that came into the shop with the weirdest combination of problems: the dome light wouldn’t turn off, the radio presets kept resetting, and the horn would randomly chirp when locking the doors. The owner had already replaced the battery and checked all the fuses. After connecting a scan tool, we found communication loss codes pointing to the BCM. These modules, especially from this era, are prone to internal solder joint fractures from years of vibration and heat cycles. Swapping in a pre-programmed BCM like this one solved every single issue in under an hour. It’s a definitive fix for problems that can otherwise seem impossible to trace.
Is Your Truck Showing These Symptoms?
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security or anti-theft light is illuminated or flashing, preventing the engine from starting.
- ✔ Erratic behavior from the radio or climate controls.
- ✔ False warnings on the instrument cluster (e.g., “door ajar” light).
- ✔ Diagnostic Trouble Codes (DTCs) related to communication loss with other modules.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes for all system capacitors to discharge.
- ✔ Locate the BCM: On the 1998 Isuzu Hombre, the BCM is typically located on the left-hand (driver’s) side of the dash. On S10, Jimmy, and Bravada models, it’s usually behind the center dash area, often near the radio.
- ✔ Remove Trim Panels: Carefully remove any dash panels or glove box components necessary to access the module. Keep track of all screws and clips.
- ✔ Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and reconnect all electrical harnesses. Ensure they click securely into place.
- ✔ Reconnect and Test: Reassemble the dash panels, reconnect the negative battery terminal, and turn the key to the ‘On’ position. Test all functions like windows, locks, lights, and wipers to confirm proper operation.
Important Post-Installation Information
While this BCM is programmed for your vehicle, some systems may require a ‘handshake’ procedure after installation. Please note the following:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be required to ensure correct brake light operation.
- No Core Charge: You can keep your old module, as there is no core charge or need to return it.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the BCM to the VIN you provide before shipping. It arrives ready for installation, saving you a trip to the dealer.
Where is the BCM located on my 1998 S10?
On the 1998 Chevy S10, GMC Sonoma, and Blazer/Jimmy models, the BCM is typically found behind the dashboard on the passenger side, often accessible by removing the glove box. On the Isuzu Hombre, it’s usually on the driver’s side.
Will this fix my truck not starting?
It can. A common failure of the BCM is with the Passlock anti-theft system. If your security light is on and the truck won’t start, a faulty BCM is a very likely cause. This programmed module will restore the security function.
What if my original part number is not 8162683950?
This module is a compatible replacement for multiple part numbers, including 09366803, 16264870, and 16268395. As long as your vehicle is on the fitment list, this part will work correctly.
Do I need special tools for the installation?
Basic hand tools like a socket set and screwdrivers are usually all that’s needed to access and replace the BCM. The only special tool that might be required post-installation is a professional-grade scan tool if the airbag light comes on.
