Is Your Chevrolet Traverse Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows with a mind of their own, or a security system that randomly activates? These frustrating and unpredictable issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, managing everything from your interior dome lights and power locks to the instrument cluster and theft-deterrent system. When it starts to fail, it can make driving your Traverse an exercise in frustration.
From the Diagnostic Bay
We had a 2015 Traverse come into the shop with a battery that would be dead every morning. The owner had already replaced the battery and alternator, but the problem persisted. After a quick parasitic draw test, we found a significant current draw even with the key off. Tracing the circuits, we discovered the BCM was keeping the interior lighting and radio circuits powered on intermittently throughout the night. Instead of a costly and time-consuming diagnostic and programming session at the dealership, we installed one of our VIN-programmed BCMs. The next morning, the battery was perfect. It’s a classic example of how a faulty BCM can cause baffling issues that have a surprisingly simple solution.
The Direct Solution: A VIN-Programmed 2013-2017 Traverse BCM
Don’t let a faulty module keep your vehicle sidelined. This Body Control Module, part number 22820314 (also compatible with 22915542), is the definitive solution to restore your vehicle’s electronic functions. We take the guesswork and hassle out of the repair process. Simply provide us with your vehicle’s Vehicle Identification Number (VIN) during checkout, and our technicians will program the module with the latest GM factory software specific to your Traverse. This means the BCM arrives at your door ready for installation, saving you a trip to the dealership and avoiding their expensive programming fees.
Common Symptoms of a Failing BCM
- ✔ Erratic Lighting: Headlights, taillights, or interior lights that flicker, stay on, or don’t work at all.
- ✔ Power Accessory Failure: Power windows, door locks, or mirrors behaving unpredictably or not responding.
- ✔ Instrument Cluster Issues: Gauges acting erratically, warning lights illuminating for no reason, or a complete loss of the display.
- ✔ Security System Problems: The anti-theft system may prevent the car from starting or the alarm may go off randomly.
- ✔ Communication Errors: A diagnostic scan tool may show a loss of communication with the BCM or other modules.
- ✔ Parasitic Battery Drain: The BCM may fail to let other modules go to ‘sleep’, causing the battery to drain overnight.
Installation and Post-Install Procedures
Once you receive your pre-programmed module, the physical installation is straightforward for a DIYer with mechanical experience or any professional technician. After installation, some vehicles may require additional relearn procedures to ensure all systems communicate correctly. Please be aware of the following:
- 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 professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and proper function of the traction control system.
We always recommend consulting a factory service manual or a qualified technician for specific guidance related to your vehicle.
Guaranteed Fitment
This BCM is a direct-fit replacement for a wide range of GM vehicles, ensuring broad compatibility. While it is a primary solution for the 2013-2017 Traverse BCM, it also fits models such as the GMC Acadia, Buick Enclave, Chevrolet Impala, Cadillac CTS, and Express/Savana vans. Please verify your original part number (22820314 or 22915542) to confirm fitment.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready to be installed, saving you time and money.
Why do you need my VIN?
Your VIN allows us to load the exact software and calibrations your vehicle had when it left the factory. This ensures all the options and features of your Traverse work correctly with the new BCM.
Where is the BCM located on a 2015 Chevy Traverse?
On the 2013-2017 Traverse, the Body Control Module is typically located on the driver’s side of the dashboard, behind the lower dash panel to the left of the steering column.
What happens if my airbag light is on after I install the BCM?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Is this a simple plug-and-play installation?
For many vehicles, it is. However, as noted, some models may require additional relearn procedures for the airbag or brake pedal position sensor. The core functionality will be restored upon installation, but these final steps may be necessary to clear all warning lights.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
