A Technician’s Notebook
I remember a 2001 Sierra 1500 that came into the shop with the owner at his wit’s end. The radio would turn on and off, the dome light wouldn’t work, and the security light was always on, sometimes preventing the truck from starting. He’d already replaced the battery and checked fuses. After connecting my scan tool, I saw multiple communication loss codes (U-codes) with various modules. This is a classic sign. The issue wasn’t the individual components; it was the central hub—the BCM—that was failing to communicate properly. Swapping in a VIN-programmed BCM like this one solved every single issue in one shot. It’s a common failure point on these GMT800 platforms.
Is Your Truck Showing These BCM Failure Signs?
- ✔ Power windows or door locks working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light is illuminated, or the vehicle won’t start (PassLock issues).
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Erratic behavior from the radio or climate controls.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, often U-codes.
Your Straightforward BCM Installation Guide
Replacing the BCM is a job a confident DIYer can handle. The key is our pre-programming service, which eliminates the most complex step.
- Safety First: Always disconnect the negative terminal from your truck’s battery before working on electrical components.
- Locate the BCM: On these GM trucks, the BCM is typically located on the driver’s side of the dashboard, to the left of the steering column. You may need to remove the lower dash panel for access.
- 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 BCM: Mount the new, pre-programmed BCM in place and securely plug in all the electrical connectors. Ensure they click 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, horn, and radio.
Important Post-Installation Note: In some cases, additional relearn procedures may be necessary. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. A ‘Brake Pedal Position Relearn’ might also be required for proper brake light and traction control operation. Always consult a factory service manual for specifics related to your vehicle.

Frequently Asked Questions
Does this BCM need to be programmed by a dealer?
No. We handle the programming for you before we ship it. Just provide your VIN during checkout, and it will arrive ready to install, saving you time and money.
Where is the BCM located on my 2001 Silverado?
The Body Control Module is located under the dashboard on the driver’s side, typically to the left of the steering column.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s SDM. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the physical replacement is straightforward. Since we pre-program the unit, you avoid the most complicated step. However, be aware that post-install relearn procedures may be needed depending on your vehicle.
Will this fix my truck’s security (PassLock) issue?
A faulty BCM is a very common cause of PassLock security system problems on these GM trucks. Replacing a bad BCM with this pre-programmed unit will often resolve those issues.
