A Technician’s Notebook: The Phantom Drain Mystery
A few months back, a 1998 S10 came into my shop with a battery that would die overnight. The owner had already replaced the battery and alternator. After checking for parasitic draws, I traced a significant one back to the BCM. It was keeping the interior courtesy light circuit active long after the doors were closed, slowly draining the battery. Swapping in a correctly programmed BCM didn’t just fix the drain; it also resolved a quirky power lock issue the owner had forgotten to mention. These modules control more than you think, and a failure can manifest in very strange ways.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The security system or horn activates randomly.
- ✔ Dashboard warning lights, such as the airbag light, illuminate without a clear cause.
- ✔ Intermittent starting problems or a no-crank condition.
- ✔ Inaccurate or dead gauges on the instrument cluster.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the Module: On the 1998 Isuzu Hombre, the BCM is typically found on the left-hand (driver’s) side of the dashboard. On S10/Blazer/Jimmy models, it’s usually behind the center dash area.
- ✔ Remove and Replace: Carefully unplug the electrical connectors from the old BCM. Unbolt it from its mounting bracket and set it aside. Mount the new module in its place and securely reconnect all wiring harnesses.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all related functions: power windows, locks, interior lights, wipers, and indicators.
Important Post-Installation Information
In some cases, additional steps with a diagnostic tool may be required after installing your new 1998 Isuzu Hombre BCM:
- Airbag System Sync: If your airbag warning light is on after installation, a professional will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new module with the airbag system.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary to ensure correct brake light operation and traction control performance.
We make the process easier by offering this module with no core charge. You can keep your old part without the hassle of shipping it back.

Frequently Asked Questions About This BCM
Frequently Asked Questions
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the correct software and vehicle-specific options from GM. This ensures the module communicates properly with your truck’s other systems right out of the box.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the physical replacement is straightforward. The BCM is typically accessible behind a dash panel. The main benefit of our service is that the complex programming is already done for you.
My airbag light is on. Will this fix it?
A faulty BCM can cause the airbag light to turn on. While this replacement part will resolve the module-related fault, the system may need to be synced using a professional scan tool after installation to turn the light off, as noted in the post-installation procedures.
What if my original part number isn’t 8093668030?
This module is a direct replacement for several part numbers. Please check the fitment list to see if your vehicle and original BCM ID (e.g., 16268395) are listed. If so, this part will work for you.
Do I need to send my old BCM back?
No. This product is sold with no core charge, so you can keep your original module without any extra cost or hassle.
