Restore Full Electrical Control to Your GM Truck or SUV
If you’re dealing with bizarre electrical gremlins in your 2001 GM truck—like power windows with a mind of their own, a security light that won’t turn off, or interior lights that flicker for no reason—you’re likely facing a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and hard-to-diagnose issues. This isn’t just an annoyance; it can affect vehicle security and functionality. We offer a direct-fit, reliable solution: a replacement BCM, part number 09375899, that arrives at your door pre-programmed to your vehicle’s specific VIN.
Forget the expensive trip to the dealership and the hassle of scheduling a programming appointment. Simply provide us with your VIN during checkout, and our technicians will flash this module with the latest GM software updates for your exact vehicle configuration. This ensures a seamless installation and restores your truck’s systems to factory-correct operation. This is the most efficient way to get a dependable fix for your 2001 Yukon BCM or related GM model.
From the Diagnostic Bay
A customer brought in his 2001 Sierra 2500 last month with a classic BCM failure story. The radio would randomly turn off, the driver’s side power lock was dead, and the ‘Security’ light was constantly on, preventing the truck from starting intermittently. He had already replaced the battery and checked fuses, but the problems persisted. After a quick scan, we saw multiple communication loss codes pointing to the BCM. Instead of a costly dealer part and programming fee, we installed one of these VIN-programmed modules. The installation took less than an hour, and once we performed the necessary security and airbag key relearn, every single issue was resolved. The customer drove away with a truck that felt new again, saving hundreds of dollars and a lot of headaches.
Is Your Truck Showing These BCM Failure Symptoms?
A failing BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your Body Control Module needs attention:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The vehicle’s security system acting up, causing no-start conditions.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Communication error codes (U-codes) stored in the system.
A Straightforward Guide to BCM Installation
Replacing the BCM on these GM trucks is a manageable task for a confident DIYer. Our pre-programmed module eliminates the most difficult step. Follow this general guide for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electrical components.
- Locate the BCM: On most 2001 GM trucks and SUVs, the BCM is located on the driver’s side of the dashboard, typically to the left of the steering column. You may need to remove the lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical harnesses. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Final Procedures: After installation, you MUST perform a few final steps to ensure all systems work correctly. See the critical information below.
Critical Post-Installation Procedures
To finalize your repair and ensure vehicle safety, the following steps are required after installing your new 2001 Yukon BCM. These procedures sync the new module with your vehicle’s other systems.
- Airbag System Reset: An active airbag warning light is common after a BCM swap. You must use a compatible diagnostic scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the BCM and the airbag system (SDM), clearing the warning light.
- Brake Pedal Position Sensor Relearn: Some vehicles may require a recalibration of the brake pedal position sensor. This is crucial for proper brake light operation and stability control functions. This procedure is also performed with a professional-grade scan tool.
Note: If you are not equipped or comfortable with these final steps, we strongly recommend seeking assistance from a qualified professional mechanic to complete the installation.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you before shipment. Just provide your vehicle’s 17-digit VIN when you order, and the module will arrive ready for installation, flashed with the latest GM software for your specific vehicle.
Where do I find my VIN?
Your Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Is this a difficult part to replace for a DIYer?
The physical replacement is straightforward for someone with basic mechanical skills. It involves removing a dash panel and a few connectors. The most critical part is performing the post-installation relearn procedures (for the airbag and brake systems), which require a proper diagnostic tool.
What happens if I don’t do the airbag system reset?
The airbag warning light will remain on, and more importantly, the airbag system may not function correctly in the event of a collision. This is a critical safety step that must not be skipped.
Will this fix my intermittent no-start problem?
If your no-start issue is caused by the factory anti-theft or security system being controlled by a faulty BCM, then yes, this part is very likely to solve the problem once installed and synced correctly.
Is this a new or used part?
This is a high-quality, inspected, and tested replacement part that is guaranteed to function correctly. We load it with fresh, vehicle-specific programming to ensure reliability.
