Are you chasing electrical gremlins in your 2001 Oldsmobile Bravada or another compatible GM vehicle? If you’re dealing with flickering lights, malfunctioning power windows, erratic gauges, or a security system that won’t cooperate, the source of your frustration is very likely a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of confusing and seemingly unrelated issues. This isn’t just an annoyance; it can affect the safety and reliability of your truck or SUV.
This is a direct-fit replacement Body Control Module, arriving at your door fully programmed to your vehicle’s specific VIN. We install the latest GM software updates, ensuring optimal performance and compatibility. This critical step eliminates the need for an expensive trip to the dealership for programming. Simply provide your VIN at checkout, and we handle the complex part for you, delivering a component that’s ready for installation right out of the box.
Case Study: A Tricky Diagnosis
I remember a 2000 Silverado in my bay a few months back that had the owner completely stumped. The radio would turn on and off by itself, the driver’s side power window worked intermittently, and the dome light had a mind of its own. The owner had already replaced the window motor and the radio head unit with no success. After connecting my scan tool, I saw a handful of ‘U’ codes, indicating communication loss between modules. This is a classic sign. The root cause wasn’t any of the individual components; it was a failing BCM corrupting the data bus. Installing a new, properly programmed BCM like this one solved all three problems instantly. It’s a perfect example of how one central part can fix a dozen headaches.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security or anti-theft system light is on, or the vehicle won’t start.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, especially communication codes like U0140.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes before beginning work.
- ✔ Locate the BCM: On the 2001 Bravada, S10, and Jimmy, the BCM is typically located behind the center of the dashboard. On other compatible trucks and SUVs, it’s usually found on the driver’s side, to the left of the steering column.
- ✔ Disconnect and Remove: Carefully 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. Securely plug in all the electrical connectors, making sure they click into place.
- ✔ Reconnect Power: Reconnect the negative battery terminal.
- ✔ Perform Relearns: Start the vehicle. If you see an airbag warning light or notice issues with brake light operation, proceed to the necessary post-installation procedures outlined below.
Important Post-Installation Steps
While this 2001 Bravada Body Control Module is designed for a simple installation, some vehicle systems may need to be re-synchronized after the BCM is replaced. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag light illuminates after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required. This must be done with a professional-grade diagnostic tool to ensure the safety system is fully operational.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor may be necessary. This ensures your brake lights and traction control system function as intended.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your VIN is essential for us to program the Body Control Module with the exact software and settings for your vehicle’s specific options. This ensures seamless integration and proper function of all electronic systems, just like a new part from the factory.
Is this a difficult part for a DIYer to install?
The physical replacement is straightforward for most DIY mechanics with basic tools. Because we pre-program the module, you skip the most difficult step. The main challenge can be accessing the module’s location within the dash.
What happens if the airbag light comes on after I install it?
This is not a sign of a defective part. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a professional scan tool, which can be performed by most automotive repair shops.
My original part number is 19208539. Will this work?
Yes. This module is a direct replacement for service numbers 9385236, 19208539, and 9371990. As long as your vehicle is on the compatibility list, this part will function correctly.
Do I have to send my old BCM back?
No. We do not require a core return for this part. You can keep your old module, which saves you money and eliminates the hassle of shipping a core back.
