Restore Full Function to Your GM Vehicle with a VIN-Programmed BCM
Are you dealing with baffling electrical issues in your 2010 Tahoe or another GM vehicle? Intermittent power windows, door locks with a mind of their own, strange warning lights, or a security system that prevents your truck from starting are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it can affect safety systems like your airbags and traction control.
As a technician with over two decades of experience, I’ve seen firsthand how a faulty BCM can sideline an otherwise perfectly good vehicle. This isn’t a part you can just swap out. A new BCM from the dealer requires expensive programming. We solve that problem for you. This is a direct-fit replacement 2010 Tahoe Body Control Module that we program to your vehicle’s specific VIN before it ships. You get a part that’s ready for installation right out of the box, loaded with the latest GM software updates to ensure peak performance and reliability.
A Technician’s Notebook: The Case of the Haunted Tahoe
I remember a 2010 Tahoe that came into my shop with a list of complaints that sounded like something out of a ghost story. The radio would change stations on its own, the dome lights would flicker while driving, and the driver’s power window would only work when it felt like it. The customer had already replaced the battery and checked all the fuses. A quick scan showed a dozen communication error codes (U-codes) pointing to a network failure. The culprit? A failing BCM. Water had wicked down a wire from a leaky A-pillar seal, causing slow corrosion on the BCM’s circuit board. Replacing it with a VIN-programmed unit like this one didn’t just fix the symptoms; it restored the vehicle’s entire communication network and the owner’s peace of mind.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not working.
- ✔ The security or anti-theft light is on, and the vehicle may not start.
- ✔ False warnings on the instrument cluster (e.g., “Service Stabilitrak,” “Service Airbag”).
- ✔ Communication issues with diagnostic scan tools, often showing codes like U0140, U0155, or other U-series codes.
- ✔ Air conditioning and climate control functions are inoperative.
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On most GM trucks and SUVs like the Tahoe, the BCM is located under the driver’s side of the dashboard, to the left of the steering column. On vans and some cars, it may be in the center dash area.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors. Most have a locking tab that needs to be depressed or a lever that needs to be swung over. Once disconnected, remove any bolts or clips holding the module in place and remove the old unit.
- ✔ Install the New Module: Seat your new, pre-programmed BCM into the mounting bracket and secure it. Firmly reconnect all electrical connectors, ensuring they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- ✔ Perform Relearns: Start the vehicle. As noted below, you may need to perform a ‘Setup SDM Primary Key’ procedure if the airbag light is on, or a ‘Brake Pedal Position Relearn’. This is often required to sync the new module with other systems in the vehicle.
Important Post-Installation Procedures
After installing your new BCM, some vehicles may require additional steps to ensure all systems function correctly. These procedures typically require a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, the “Setup SDM Primary Key in BCM” procedure is necessary to re-establish communication between the BCM and the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct operation of the brake lights and the traction/stability control systems.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for procedures specific to your vehicle.

Frequently Asked Questions
How does the VIN programming service work?
It’s simple. After you complete your purchase, you will provide us with your vehicle’s 17-digit VIN. Our technicians will then program this BCM with the latest GM-certified software specific to your vehicle’s features and options before we ship it out.
Is this part truly plug-and-play?
Because we program it to your VIN, it eliminates the need for dealer programming. For most users, it is a direct installation. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake sensor, which require a professional scan tool.
What if my original part number is not 15921353?
This module is a hardware replacement for a wide range of part numbers. As long as your original part number is on our compatibility list, this module will function correctly in your vehicle once programmed to your VIN.
Do I need to send my old BCM to you?
No. This is a replacement part, not a repair service for your original. Per our policy, we do not require your original module (core). We ship you a programmed replacement, and you can dispose of your old one.
Will this fix my ‘Service Airbag’ light?
If the BCM is the cause of the light, yes. However, after installation, you may need to have the ‘Setup SDM Primary Key in BCM’ procedure performed with a scan tool to sync the new BCM with the airbag module and turn off the light.
