Restore Your Truck’s Electrical System with Confidence
Are you battling bizarre electrical problems in your 2001 GM truck or SUV? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM).

Expert Insight: The GMT800 Electrical Workhorse
The 2001 GM truck and SUV platform (GMT800) is legendary for its durability, but its BCM is a known weak point after two decades of service. These modules manage a surprising number of functions, and when they fail, the symptoms can seem random and unrelated. Many owners chase expensive wiring repairs or replace individual components like switches, only to find the core problem was the BCM all along. Opting for a pre-programmed 2001 Suburban 2500 BCM 9370249 is the smartest, most efficient repair. It addresses the root cause and comes loaded with updated software that can improve upon the original factory programming, giving your trusted vehicle a new lease on life.
Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require one or more of the following procedures to be completed with a professional-grade scan tool to ensure all systems are synced correctly:
- Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure is necessary.
- Brake Pedal Position Relearn: A recalibration may be needed for proper brake light and traction control function.
We provide this information to ensure you have a complete understanding of the repair process. Always consult a factory service manual or a qualified technician if you are unsure about any step.
Frequently Asked Questions
Do I need to program this BCM?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide us with your vehicle’s 17-digit VIN during or after checkout, and we will flash the BCM with the correct software and calibration files for your specific truck or SUV.
Where is the BCM located on my 2001 Suburban?
The Body Control Module on these GM models is typically located on the driver’s side, up under the dashboard to the left of the steering column. It is a black plastic box with several large electrical connectors.
Why do you need my VIN?
The Vehicle Identification Number (VIN) allows us to access the exact factory software and settings for your vehicle’s specific options, such as drivetrain (4×4 vs 4×2), power accessories, and security system. This ensures the replacement 2001 Suburban 2500 BCM 9370249 works perfectly.
Will this fix my ‘Service 4WD’ light?
While the BCM communicates with the 4WD system, a ‘Service 4WD’ light is most often caused by a faulty transfer case encoder motor, selector switch, or a problem with the Transfer Case Control Module (TCCM). It is important to have the vehicle properly diagnosed to pinpoint the exact cause.
What if I have an airbag light on after installation?
As noted in the description, if the airbag light comes on, it means the new BCM needs to be electronically ‘introduced’ to the vehicle’s airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a bi-directional scan tool to sync the systems and turn off the light.
Is this a difficult part to replace myself?
For someone with basic mechanical skills, the physical replacement is straightforward. It involves removing a few dash panels for access and disconnecting the electrical connectors. The most critical part is ensuring any necessary post-install relearn procedures are performed correctly, which may require a professional scan tool.
