Restore Your Vehicle’s Electrical Functions
Are you chasing down frustrating electrical gremlins in your 2001 Oldsmobile Bravada or other compatible GM vehicle? Intermittent power windows, flickering lights, a security system that has a mind of its own, or even a no-start condition can often be traced back to a single component: the Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a failing BCM can cause a cascade of confusing and unpredictable issues. This replacement Body Control Module, part number 09371990, is the reliable, straightforward solution to restore order and get your vehicle operating as it should.
Case Study: A Tricky Diagnosis
I remember a 2001 GMC Jimmy S15 that came into my shop with a laundry list of complaints from the owner. The dome lights wouldn’t turn off, the power locks worked only half the time, and the radio would randomly shut down. The owner had already replaced the battery and checked all the fuses. After connecting my scan tool, I found a series of ‘U’ codes, indicating a loss of communication between various modules. This pointed me directly to the BCM. These modules, especially on this GM platform, are prone to internal circuit board failures over time. Swapping in a pre-programmed BCM like this one resolved all the issues in under an hour, saving the customer hundreds compared to a dealership visit.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or anti-theft light flashing, preventing the engine from starting.
- ✔ Inconsistent or non-working radio and instrument cluster gauges.
- ✔ Diagnostic Trouble Codes (DTCs) related to loss of communication, such as U1000.
- ✔ Unpredictable battery drain when the vehicle is off.
The Smart Solution: Pre-Programmed for Your Vehicle
The biggest hurdle in replacing a BCM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. When you purchase this module, simply provide us with your vehicle’s VIN. Our technicians will flash the BCM with the latest GM software updates specific to your vehicle. It arrives at your door ready to be installed, saving you time, money, and a trip to the dealer. Plus, there is no core charge, so you can keep your old part.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2001 Bravada, S10, and Jimmy, the BCM is typically located behind the center of the dashboard, often near the radio or climate controls. For most other listed GM trucks and SUVs, it’s found on the driver’s side, under the dash to the left of the steering column.
- ✔ Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the BCM. 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 and remove it.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM into the bracket and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reassemble and Reconnect: Reinstall any trim panels you removed. Finally, reconnect the negative battery terminal.
Important Post-Installation Steps
After installation, your vehicle should start and run. However, some systems may require recalibration to communicate properly with the new 2001 Bravada BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure correct brake light operation and traction control functionality.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready for installation, making this a plug-and-play repair.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact factory software and calibrations for your specific model, year, and options, ensuring perfect compatibility.
Is there a core charge or do I have to send my old part back?
There is absolutely no core charge. You can keep your old module, saving you the hassle and cost of return shipping.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a high-level, bi-directional diagnostic scan tool, typically used by professional mechanics. Many local repair shops can perform these services for you if needed.
Will this 2001 Bravada BCM fix my no-start problem?
A faulty BCM is a common cause of no-start conditions, especially if the security light is flashing. While this module will correct a BCM-related issue, a no-start can have other causes. Proper diagnosis is always recommended.
