If you’re dealing with bizarre electrical issues in your 2001 Chevy S10, GMC Sonoma, or another compatible GM vehicle, you’ve likely met the frustration of a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen it all: dome lights with a mind of their own, power windows that won’t budge, and a security light that keeps your truck from starting. These aren’t separate problems; they’re symptoms of a failing BCM, the central hub for your vehicle’s body electronics.
Don’t waste time and money at a dealership with diagnostic fees and programming charges. We offer a direct, reliable solution. This Body Control Module, part number 9385236, arrives at your door pre-programmed with the latest GM software, specifically flashed to your vehicle’s VIN. This ensures seamless integration and restores functionality right out of the box. It’s the straightforward fix that gets your reliable truck back to being reliable.
Is Your Truck Showing These Symptoms?
- ✔ Erratic or non-working power windows and door locks.
- ✔ Interior lights flickering, staying on, or not working at all.
- ✔ The security or anti-theft light is on, possibly causing a no-start condition.
- ✔ Wipers, radio, or instrument cluster gauges behaving unpredictably.
- ✔ False warning lights on the dash without an actual mechanical fault.
- ✔ Communication error codes (often U-codes) when scanned with a diagnostic tool.
Case Study: A Tricky Diagnosis
A customer brought in his ’01 GMC Jimmy with a classic electrical gremlin story. His radio would cut out, the dome light would flicker while driving, and occasionally, the power locks would stop responding. He’d already replaced the battery and checked fuses, but the problems persisted. On the diagnostic scanner, I found a handful of communication codes pointing to a network issue. Instead of chasing wires for hours, experience told me to look at the BCM. We swapped in one of our VIN-programmed modules, and in under 30 minutes, every single issue was gone. It’s a reminder that sometimes the most complex-seeming problems have a simple, central solution.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2001 S10, S15, Sonoma, Blazer, and Jimmy, the BCM is typically located in the center of the dash, often accessible by removing the passenger-side hush panel or glove box. For full-size trucks and vans like the Silverado or Astro, it’s usually on the driver’s side, to the left of the steering column.
- ✔ Disconnect and Remove: Carefully 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 Module: Seat your new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a click as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions – windows, locks, lights, wipers, and radio – to confirm proper operation.
Important Post-Installation Information
While our BCM is programmed for a direct fit, some GM systems require a ‘handshake’ after a new module is introduced. Be aware of the following potential procedures:
- 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 relearn may be required to ensure your brake lights and traction control system function correctly.
Disclaimer: We are committed to your success. However, specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to program this module?
No. We handle all the programming for you. Simply provide your vehicle’s VIN during checkout, and we will flash the module with the latest GM software specific to your truck before shipping.
What does the Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, interior and exterior lighting, wipers, the security system, and the radio.
Where is the BCM located on my 2001 S10?
On the 2001 S10 and Sonoma platform trucks and SUVs, the BCM is typically found behind the passenger side of the dashboard, often accessible after removing the glove box or the lower dash panel.
Will this fix my security light issue?
In many cases, yes. A faulty BCM is a very common cause for an illuminated security light and a no-start condition on these GM vehicles. This module is programmed to work with your existing keys and security system.
Is there a core charge?
No. We do not require you to send back your old module. There is no core charge associated with this purchase, saving you time and return shipping costs.
