Is your 2001 GM truck or SUV plagued by mysterious electrical problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. When it begins to fail, it can cause a cascade of confusing and frustrating issues that seem unrelated. From flickering lights to a vehicle that won’t start, a faulty BCM can make your reliable truck feel unpredictable. This replacement Body Control Module is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
This unit arrives at your door pre-programmed with the latest GM software updates, specifically matched to your vehicle using the VIN you provide. This critical step eliminates the need for expensive programming at a dealership, saving you time and money. It’s a direct-fit replacement for part number 9370249 and other interchangeable numbers, ensuring a straightforward installation process.
From the Diagnostic Bay
We had a 2001 Sierra 2500 in the shop that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and the power door locks worked only when they wanted to. The owner had already replaced the door lock actuators and the headlight switch with no success. After hooking up our diagnostic tool, we saw multiple communication error codes all pointing back to one component: the BCM. Once we installed a VIN-programmed module like this one, all the strange electrical gremlins vanished instantly. It’s a perfect example of how one central module can be the root cause of many seemingly separate problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system light flashing, preventing the engine from starting (PassLock issues).
- ✔ The radio or instrument cluster randomly turning on or off.
- ✔ False warning messages on the driver information center (e.g., “Service 4WD”).
- ✔ Inconsistent HVAC (heating and air conditioning) blower fan operation.
- ✔ Rapid battery drain while the vehicle is parked.

Post-Installation Information
While this module is pre-programmed for your convenience, some GM vehicles of this era may require simple relearn procedures after installation to sync with other modules. These are standard procedures for any BCM replacement.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
How does the VIN programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to load the exact GM software and calibrations for your truck’s specific features onto the BCM before shipping it to you.
Is this part truly plug-and-play?
It is pre-programmed, which handles the most difficult part of the installation. However, as with any BCM replacement on these vehicles, you may need to perform additional relearn procedures for systems like the airbags or brake sensor, which may require a professional scan tool.
What happens if my airbag light is on after I install it?
This indicates that the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A mechanic with a bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ function to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this fix the security light and no-start problem?
A failing BCM is a very common cause of PassLock security system issues on these GM trucks. Replacing it with a correctly programmed module is the most reliable way to solve that specific problem.
