Restore Full Functionality to Your 2001 GM Truck or SUV
Are you battling frustrating electrical issues in your 2001 GMC Yukon, Tahoe, or Silverado? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable truck into a source of daily headaches. It’s the central command for your vehicle’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
We offer a dependable and straightforward solution. This Body Control Module, part number 9370249, is the definitive fix for these problems. The best part? We handle the programming for you. Simply provide your vehicle’s VIN during checkout, and our experts will flash the module with the latest GM software specific to your truck. It arrives at your door ready to install, saving you a costly trip to the dealership and hours of diagnostic guesswork.
From the Diagnostic Bay: The Ghost in the Machine
A customer brought in his 2001 Silverado 1500 last month with a list of bizarre symptoms. The dome light would stay on, the radio presets would randomly reset, and the horn would chirp when he used the turn signal. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I noticed communication errors between several modules, all pointing back to one source. We swapped in a pre-programmed BCM, and instantly, all the gremlins vanished. It’s a common failure point on these GMT800 platforms, but a correctly programmed module is a night-and-day difference.
Is Your GM Truck Showing These Signs?
- ✔ Erratic or non-functional interior/exterior lights
- ✔ Power windows, door locks, or mirrors working intermittently
- ✔ Security system or keyless entry failing
- ✔ Radio or climate control display issues
- ✔ False warnings on the driver information center (DIC)
- ✔ A persistent “Service Vehicle Soon” light
A Straightforward Guide to Installation
Replacing the 2001 Yukon BCM is a manageable job for a confident DIYer. It’s typically located under the driver’s side of the dashboard. Follow these steps for a successful installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the systems to discharge.
- Locate the BCM: On most of these models, you’ll find it attached to a bracket 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. They have locking tabs, so be gentle. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed BCM into place and securely reconnect all the electrical harnesses. You should hear a ‘click’ as they lock in.
- Reconnect Power: Reattach the negative battery terminal.
- CRITICAL Post-Installation Steps: After installation, two procedures are essential. First, you must have a qualified technician perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to clear the airbag light. Second, some vehicles may require a Brake Pedal Position Sensor recalibration to ensure proper brake light function and ABS performance. Do not skip these steps.

Frequently Asked Questions about the 2001 Yukon BCM
Do I need to program this BCM after I receive it?
No. We program the module to your vehicle’s specific VIN before shipping. It arrives ready for installation, with no dealership visit required for programming.
What exactly does a Body Control Module do?
The BCM is a computer that controls most of your vehicle’s non-engine-related electronic functions, such as power windows, locks, lights, wipers, security system, and climate controls.
Where is the BCM located on my 2001 Yukon or Silverado?
It is typically found under the driver’s side dashboard, to the left of the steering column. You will likely need to remove the lower dash trim panel to access it.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the correct factory software and vehicle options from GM’s database. This ensures the BCM works perfectly with your specific truck’s features.
Will this fix my airbag light?
Replacing the BCM will likely turn on the airbag light. You must perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible diagnostic tool to reset the light and ensure the safety system is operational.
Is any other relearn procedure required?
Some vehicles may require a brake pedal position sensor recalibration after BCM replacement. This is crucial for proper brake light operation and overall vehicle safety. We recommend consulting a service manual or a professional technician.
