Are you tired of chasing down electrical gremlins in your 2001 Chevy S10 or GMC Sonoma? One minute the power windows work, the next they don’t. Maybe the security light is flashing, or the interior lights have a mind of their own. As a technician with over 20 years of experience, I can tell you these frustrating, intermittent issues often point directly to a failing Body Control Module (BCM). This isn’t just an inconvenience; it can affect your vehicle’s security and daily operation. This is the reliable, long-term fix you’ve been looking for.
This is a replacement Body Control Module for your GM truck or SUV, arriving at your door fully programmed to your vehicle’s specific VIN. We install the latest GM software updates before it ships, which often corrects factory flaws and improves performance. This means you can skip the expensive trip to the dealership for programming. Just provide your VIN at checkout, and we handle the rest. It’s the most direct path to getting your truck back to 100%.
From the Diagnostic Bay
I remember a 2001 GMC Jimmy that came into my shop with a classic case of BCM failure. The owner was frustrated because his power locks were working sporadically and the radio would shut off randomly. He’d already replaced the battery and checked fuses. After plugging in my scan tool, I saw several communication error codes (U-codes) pointing to the BCM. We installed one of these VIN-programmed modules, and within an hour, all the strange electrical issues were gone. It’s a common failure, and having a pre-programmed unit saves hours of diagnostic and programming time.
Is Your Truck Showing These Symptoms?
A failing BCM can cause a wide range of confusing problems. If you’re experiencing any of the following, this module is likely the solution:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights staying on or not turning on at all.
- ✔ The security or anti-theft light flashing, sometimes causing a no-start condition.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers operating intermittently or not parking in the correct position.
- ✔ Diagnostic trouble codes related to communication loss with the BCM (e.g., U1000).
A Straightforward Guide to Installation
Installing your new BCM is a manageable job for a DIYer. On the 2001 S10/S15/Sonoma, the BCM is typically located in the center of the dashboard, often behind the radio or climate controls. Follow these general steps:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronics.
- Access the Module: Carefully remove the necessary dash trim panels to gain access to the BCM. This may involve removing the radio or glove box on some models.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
- Final Steps: Reassemble your dashboard and reconnect the negative battery terminal. Start the vehicle and test all functions (windows, locks, lights, etc.).
Important Post-Installation Note: In some cases, additional steps may be needed. If your airbag light is on, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ might be necessary on certain models to ensure proper brake light and traction control operation. Always consult a factory service manual for specifics related to your vehicle.

Frequently Asked Questions
Do I need to program this 2001 S10 BCM?
No. We program the module to your vehicle’s VIN before we ship it. It arrives ready for installation, saving you a trip to the dealer.
Where is the BCM located on my 2001 S10?
On the 2001 S10, S15, Sonoma, Blazer, and Jimmy, the BCM is typically found in the center of the dashboard, behind the radio or HVAC control panel.
What happens after I purchase?
After you place your order, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
What if my airbag light is on after installation?
If the airbag light illuminates, the BCM needs to be synced with the airbag system’s SDM module. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
