Tired of Chasing Electrical Gremlins in Your GM Truck?
If you’re dealing with flickering lights, power windows with a mind of their own, a security light that won’t turn off, or other bizarre electrical issues in your 2001 GM truck or SUV, you’ve likely met the culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s body electronics, when the BCM starts to go, it can cause a cascade of frustrating and seemingly unrelated problems. I’ve seen it hundreds of times in my 20+ years as a technician. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
This is your direct, reliable solution. We offer a replacement Body Control Module, part number 09370249, that arrives at your door programmed specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and we’ll flash the module with the latest GM software updates. This critical step ensures all the options and features your truck came with from the factory work correctly, saving you a costly trip to the dealership for programming.
From the Diagnostic Bay: A Technician’s Notebook
A customer’s 2001 Silverado 1500 came in last month with a classic BCM failure story. The radio would turn on by itself, the dome lights wouldn’t work, and the power locks were intermittent. He had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple communication loss codes with the BCM. These modules, especially on the GMT800 platform, are prone to internal solder joint failures from years of heat cycles and vibration. We installed one of our VIN-programmed modules, and within an hour, every single issue was resolved. This is the definitive fix for these specific symptoms.
Is Your GM Truck Showing These Symptoms?
A faulty BCM can manifest in many ways. If you’re noticing any of the following, it’s a strong indicator that your module needs attention:
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security system light is on, or the vehicle won’t start due to a false theft alert.
- ✔ The radio or climate control display is behaving strangely.
- ✔ The horn honks randomly or doesn’t work when pressed.
- ✔ False warning messages on the driver information center (DIC).
A Straightforward Guide to Your 2001 Yukon BCM Installation
Replacing the BCM is a manageable job for a DIYer with basic tools. The module is typically located under the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most of these GM trucks, you’ll find the BCM mounted to the left of the steering column, under the dash. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the multiple electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Power: Reattach the negative battery terminal.
- CRITICAL Final Steps: After installation, two procedures are often necessary. You will need a capable diagnostic scan tool to perform the ‘Setup SDM Primary Key in BCM’ function to clear the airbag light. Some vehicles may also require a Brake Pedal Position Sensor recalibration to ensure proper brake light and ABS function. If you are not equipped to do this, a professional mechanic can perform these steps quickly.

Frequently Asked Questions
Why do you need my VIN?
Your VIN allows us to program the BCM with the exact software and vehicle-specific options (like keyless entry, power seats, etc.) that your truck was built with. This makes the installation a direct replacement without needing a trip to the dealer for expensive programming.
Is this a difficult part to replace myself?
The physical replacement is straightforward for most DIYers with basic hand tools. The main challenge is accessing the module under the dash. The most critical part is the post-installation electronic setup (Airbag and Brake Pedal), which may require a professional scan tool.
Will this fix my ‘Security’ light issue?
In many cases, yes. The BCM is a core part of the Passlock security system. A failing BCM is a very common cause of a persistent security light and no-start conditions on these GM trucks.
What happens if I don’t do the airbag and brake pedal procedures?
If the ‘Setup SDM Primary Key’ is not performed, your airbag warning light will remain illuminated, and the system may not function correctly in an accident. Skipping the brake pedal recalibration (if required for your vehicle) could lead to improper brake light operation or issues with stability control.
How do I send you my VIN?
After you complete your purchase, you will receive instructions on how to reply with your 17-digit VIN. We cannot ship your order until we receive this information, as the programming is a required step.
