Restore Full Functionality to Your GM SUV
Are you dealing with baffling electrical problems in your 2001 GMC Yukon or a similar GM truck? One minute the power windows work, the next they don’t. Maybe the security light is flashing, preventing your truck from starting, or the interior lights have a mind of their own. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause widespread and intermittent chaos. This isn’t a part you can ignore.
We offer a straightforward, reliable solution: a replacement BCM, part number 9370249, that arrives at your door pre-programmed to your vehicle’s specific VIN. We handle the complex part—flashing the module with the latest GM software—so you don’t have to. This eliminates the need for an expensive trip to the dealership for programming. By providing us with your VIN during checkout, you receive a component that is truly ready for installation, designed to restore the precise electronic functions your truck had when it left the factory.
A Technician’s Notebook: The Intermittent Gremlin
A customer’s 2001 Yukon XL 1500 came into the shop last month with a list of complaints that seemed unrelated. The radio would cut out, the driver’s side power lock was dead, and the dome lights would flicker while driving. They had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I saw multiple communication loss codes with various modules. This immediately pointed me toward the BCM. In my 20 years of experience, these intermittent, multi-system electrical faults are textbook BCM failure. We installed a VIN-programmed module, and every single issue was resolved instantly. The customer was thrilled to have their truck back to normal without the guesswork.
Common Signs of a Failing BCM
If your truck is experiencing these issues, a faulty BCM is the likely culprit. Replacing your 2001 Yukon BCM can be the definitive fix.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Instrument cluster gauges behaving strangely or not working at all.
- ✔ The security or anti-theft light stays on, causing a no-start condition.
- ✔ Interior and exterior lights flickering, staying on, or not turning on.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ False warnings appearing on the driver information center.
A Straightforward Guide to Installation
Installing your new 2001 Yukon BCM is a manageable job for a DIYer. 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 electrical components.
- Locate the BCM: On these GM SUVs, the BCM is usually found to the left of the steering column, mounted to a bracket. 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 need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM onto the bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- Reconnect Power: Reconnect the negative battery terminal.
- Perform Final Procedures: Turn the key to the ‘ON’ position. Follow the critical post-installation steps outlined below to ensure all systems, like airbags and brakes, are properly calibrated.
Important Post-Installation Calibrations
After installing your new BCM, a couple of final steps are required to ensure vehicle safety and functionality. These procedures require a professional-grade scan tool.
- Airbag System Reset: To clear the airbag warning light, the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This re-establishes communication between the new BCM and the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Sensor Calibration: Some vehicles require the Brake Pedal Position (BPP) sensor to be recalibrated. This ensures the brake lights and stability control system receive accurate input from the brake pedal.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the 2001 Yukon BCM to the VIN you provide before shipping. It arrives ready for installation and final calibration procedures.
What happens if I don’t provide my VIN?
We cannot ship the module without your vehicle’s 17-digit VIN. The programming is essential for the BCM to communicate correctly with your truck’s other electronic systems.
Will this fix my truck’s security light and no-start problem?
Yes, a faulty BCM is a very common cause of security system issues (like Passlock) in these GM vehicles. A properly programmed replacement BCM is the correct fix for this problem.
Why is the airbag light on after installation?
The airbag light is a safety feature. After replacing the BCM, the system requires a ‘key relearn’ procedure (‘Setup SDM Primary Key in BCM’) with a scan tool to verify the new module and ensure the airbag system is fully operational.
Can I use a BCM from a junkyard?
While possible, it is not recommended. A used BCM will be programmed to a different vehicle’s VIN and options, which will cause compatibility issues. Our new, correctly programmed modules ensure a proper and lasting repair.
