Is Your GM Truck or SUV Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows with a mind of their own, or a security system that prevents your truck from starting? These frustrating and seemingly random electrical issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your interior lights and power locks to the horn and anti-theft system. When it starts to fail, it can create a cascade of problems that are difficult to diagnose.
The Direct-Fit, Programmed Solution
Instead of paying for expensive diagnostic time and dealership programming fees, get the solution delivered to your door. This Body Control Module is a direct replacement for your original unit and comes professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). We install the latest software updates from GM, ensuring optimal performance and compatibility. This critical programming step means you can avoid a trip to the dealer and get your truck back to full functionality faster.
Common Symptoms of a Failing 2001 S10 Body Control Module
- ✔ Power windows or door locks operate intermittently or not at all.
- ✔ The anti-theft or security light is illuminated, potentially causing a no-start condition.
- ✔ Interior dome lights or exterior lights stay on or fail to turn on.
- ✔ The horn sounds randomly or doesn’t work when pressed.
- ✔ Dashboard gauges behave erratically or warning lights flash without reason.
- ✔ Windshield wipers activate on their own or won’t shut off.
- ✔ Remote keyless entry stops functioning correctly.
Installation and Post-Install Procedures
Physically replacing the BCM is straightforward. On models like the S10, Blazer, and Jimmy, it’s typically located in the center dash area. On full-size trucks and SUVs like the Silverado and Tahoe, it’s found on the driver’s side (LH) of the dash. Always disconnect the battery before beginning work.
Because this module is pre-programmed, it is designed to be a simple installation. However, in some cases, your vehicle’s other electronic systems may need to be re-synced to the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This is a security handshake between the airbag module and the new BCM and must be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Guaranteed Fitment
This module is a direct replacement for service numbers 19208539, 9371990, and 9385236. It is compatible with a wide range of 2000 and 2001 GM vehicles, including the Chevy S10, Blazer, Silverado, Suburban, Tahoe, and their GMC counterparts like the Sonoma, Jimmy, Sierra, and Yukon. Upon purchase, simply provide us with your VIN, and we’ll handle the rest.
Frequently Asked Questions
Is this BCM a plug-and-play part?
Yes, this BCM comes programmed to your vehicle’s VIN, making it as close to plug-and-play as possible. In some cases, minor relearn procedures, such as for the airbag or brake systems, may be required after installation using a diagnostic tool.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your truck.
Will this fix my ‘Security’ light problem?
A faulty BCM is a very common cause of an illuminated security light and a no-start condition in these GM vehicles. While other issues can cause this, replacing a failed BCM with our pre-programmed unit is a highly effective solution for this specific problem.
What if the airbag light comes on after I install it?
If the airbag light appears, it means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
