Restore Your Traverse’s Electrical System with a Plug-and-Play BCM
Are you chasing down frustrating electrical gremlins in your 2013-2017 Chevrolet Traverse? Intermittent power windows, flickering dash lights, malfunctioning door locks, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of confusing and seemingly unrelated problems. Stop the guesswork and replace the faulty component with a reliable, pre-programmed solution.
I remember a 2015 Traverse that came into the shop with a complaint that would drive any owner crazy. The radio would turn off randomly, the driver’s side power window wouldn’t work, and the instrument cluster lights would flicker occasionally. The customer had already replaced the battery and checked fuses. After connecting my scan tool, I found a series of communication error codes (U-codes) pointing to a network issue. Instead of a complex wiring problem, experience told me to look at the central hub: the BCM. A failing BCM can’t properly direct traffic on the vehicle’s data network, leading to these exact kinds of phantom issues. A new, correctly programmed BCM resolved all problems in one go.
Is Your Traverse Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Inaccurate readings on the instrument panel gauges.
- ✔ Warning lights such as the airbag or traction control light illuminating.
- ✔ Communication error codes stored, such as U0140, U0155, or other U-codes.
The Smart Solution: Pre-Programmed for Your VIN
This isn’t just a replacement part; it’s a complete solution. We take a genuine OEM BCM and flash it with the latest GM software, specifically matched to your vehicle’s VIN. This means you can skip the expensive and time-consuming trip to the dealership for programming. We do the complex part for you, so you receive a module that’s ready for installation right out of the box. Plus, with our No Core Charge policy, you can keep your original module without any extra fees or hassle.
A Straightforward Guide to BCM Installation
Replacing the 2013-2017 Traverse BCM is a manageable job for a confident DIYer. The BCM is typically located on the driver’s side, behind the lower dashboard panel.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- Locate the BCM: On the Traverse, you’ll find the BCM to the left of the steering column. You may need to remove the lower dash trim 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 Module: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Start the vehicle and test all functions—lights, windows, locks, etc.—to ensure proper operation.
Important Post-Installation Information
In some cases, additional steps may be required after installation to ensure all vehicle systems are synchronized:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only needed if the light appears.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control functionality.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls functions that aren’t related to the engine, such as power windows, locks, lights, wipers, the security system, and the instrument cluster.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as we program the module specifically for your car.
Is this a guaranteed fix for my vehicle’s issues?
This part resolves issues directly caused by a faulty BCM. If your vehicle’s symptoms match those listed, there is a very high probability this will be the solution. However, proper vehicle diagnosis is always recommended, as wiring or sensor issues can sometimes mimic BCM failure.
Will I need any special tools for installation?
For the physical replacement, you’ll typically only need basic hand tools like a socket set and a trim removal tool. However, as noted, a professional-grade scan tool may be required for post-installation procedures like an airbag system sync if the warning light appears.
What happens if my airbag light comes on after I install it?
This is not a defect but a security feature. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A repair shop with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Why is your programmed module a better choice than a used one from a junkyard?
A used BCM from another vehicle is locked to that car’s VIN and options. It will not work correctly in your Traverse without being wiped and reprogrammed by a dealer, which can be costly. Our module arrives programmed to your specific VIN, saving you that significant extra step and expense.
