Is Your Chevrolet Traverse Experiencing Strange Electrical Problems?
The Body Control Module (BCM) is the central command center for your vehicle’s body electronics. It manages everything from your power windows and door locks to the interior lights, security system, and key fob functions. When the BCM starts to fail, it can cause a cascade of confusing and intermittent issues that are often difficult to diagnose. If your Traverse is acting possessed, a faulty BCM is a very likely culprit.
From the Diagnostic Bay
We had a 2011 Traverse come into the shop that was giving its owner headaches. The radio would randomly change stations, the dome lights would flicker while driving, and the key fob would only work sporadically. After checking the usual suspects like fuses and wiring, we hooked up our diagnostic tool and found multiple communication errors pointing directly to the BCM. Replacing it with a pre-programmed unit like this one solved every single issue instantly. It’s a common failure point that can mimic a dozen other problems.

Common Symptoms of a Failing BCM:
- ✔ Power windows or door locks operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not working.
- ✔ The security system engaging randomly or the anti-theft light staying on.
- ✔ Keyless entry remote (fob) not responding.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ False warnings appearing on the instrument cluster.
- ✔ Wipers or horn activating without input.
Installation and Post-Install Notes
This BCM is typically located on the left-hand (driver’s) side of the dash. While the physical swap is straightforward for a DIYer with moderate experience, please be aware of potential post-installation procedures. Depending on your vehicle’s specific configuration, a couple of relearn procedures may be necessary to ensure all systems communicate correctly with the new module.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
This module is a direct replacement for a wide range of GM part numbers, including 15948438, 22860591, 25892622, and many others listed in the fitment data. Ensure you provide your vehicle’s VIN upon purchase for correct programming.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during checkout, and the module will arrive ready for installation.
What does the Body Control Module do on my Traverse?
The BCM acts as the main computer for your vehicle’s comfort and convenience electronics. It controls functions like power windows, locks, interior lighting, security system, and key fob recognition.
Where is the BCM located?
On the 2009-2012 Chevrolet Traverse, the BCM is typically found behind the dashboard on the driver’s side.
What happens if the airbag light comes on after I install this?
This indicates the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade scan tool to resolve this.
