Restore Full Functionality to Your GM Truck or SUV
Is your Oldsmobile Bravada, Chevy S10, GMC Jimmy, or Silverado experiencing a host of bizarre electrical problems? Issues like malfunctioning power windows, erratic door locks, intermittent interior lights, or a security system that won’t behave are often not individual component failures, but symptoms of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can create frustrating and difficult-to-diagnose problems. This replacement Body Control Module, part number 09366801, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
From the Diagnostic Bay
We had a 1999 GMC Sierra in the shop that was driving the owner crazy. The dome light would stay on, the power locks worked only when they wanted to, and the radio would randomly shut off. The owner had already replaced the door lock actuators and the dome light switch, spending hundreds with no success. After a quick scan, we saw multiple communication codes pointing to a network failure. We traced it back to the BCM. Instead of a complex and expensive repair at the dealership, we installed one of our VIN-programmed modules. In under an hour, every single one of his electrical gremlins was gone. It’s a classic case where the root cause is the central computer, not all the individual parts it controls.
Common Symptoms of a Failing BCM
- ✔ Power windows or locks working intermittently or not at all.
- ✔ Interior or exterior lights staying on or not turning on.
- ✔ The vehicle’s security system or alarm malfunctioning.
- ✔ Erratic or non-functional dashboard gauges.
- ✔ Radio or climate control issues.
- ✔ A “Service Engine Soon” or other warning light with no obvious cause.
- ✔ Inability to communicate with the module using a diagnostic scan tool.
The Simple Solution for Your 1998 Bravada BCM
Don’t let a faulty BCM keep you from enjoying your vehicle. Our replacement modules offer a streamlined and reliable fix. The biggest hurdle in replacing a BCM is the need for expensive programming at a dealership. We eliminate that step entirely. When you purchase from us, you simply provide your vehicle’s VIN, and our technicians will program the module with the latest GM software specific to your vehicle’s configuration. This ensures that when the part arrives, it’s ready for a straightforward installation, saving you time, money, and a trip to the dealer.
Installation and Required Procedures
Installation is typically a plug-and-play process. Locate your original BCM (often found in the center or left-hand side of the dash), disconnect the battery, swap the modules, and reconnect the battery. However, in some GM vehicles of this era, additional steps may be required to sync the new module with other systems.
Please be aware of the following potential post-installation procedures:
- Airbag System Sync: If the airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to synchronize the new BCM with the airbag system and extinguish the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and proper function of the traction control system.
We offer this module with no core charge, so you can keep your original part. This unit is a direct replacement for a wide range of part numbers, including: 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, and 09366801.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Is this part difficult to install?
The physical installation is generally simple, involving unplugging the old module and plugging in the new one. However, as noted, some vehicles may require a professional scan tool to perform an airbag system sync or brake pedal position relearn after installation.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific options and features. This makes the installation process as close to plug-and-play as possible and ensures proper functionality.
Will this BCM fix my specific problem?
This module is designed to correct issues directly caused by a failing BCM, such as the common symptoms listed above. While it solves the vast majority of electrical gremlins, it’s always best to have a proper diagnosis to confirm the BCM is the source of the fault.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system. A qualified mechanic with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
