If your scan tool isn’t working on your 2014 Chevy Traverse, you’re not alone. Many Traverse owners have encountered this frustrating issue, often turning to forums like Edmunds.com for help. This comprehensive guide will walk you through the common causes and solutions to get your scan tool communicating effectively with your vehicle.
Common Reasons Why Your Scan Tool Isn’t Working
Several factors can contribute to scan tool connectivity problems. Let’s explore the most frequent culprits and how to address them.
Fuse Issues
A blown fuse in the OBD-II port circuit can prevent power from reaching the port and, consequently, your scan tool. Check your owner’s manual for the specific fuse location and replace any blown fuses.
OBD-II Port Problems
The OBD-II port itself can sometimes be the source of the problem. Bent or corroded pins can disrupt the connection. Carefully inspect the port for any damage and clean it with compressed air or a specialized contact cleaner.
Wiring Harness Damage
Damage to the wiring harness leading to the OBD-II port can also interrupt communication. Look for any signs of fraying, cuts, or loose connections. If you find any damage, repair or replace the affected wiring.
Incompatible Scan Tool
Not all scan tools are created equal. Some basic code readers may not be compatible with all vehicle makes and models, especially newer ones like the 2014 Traverse. Ensure your scan tool supports GM vehicles and is updated with the latest software.

Advanced Troubleshooting and Professional Help
If the basic troubleshooting steps don’t resolve the issue, you may need more advanced diagnostics.
Check for Diagnostic Trouble Codes (DTCs)
Even if your generic scan tool isn’t working, some vehicles can store DTCs in their computer systems. Try using a different scan tool or consulting a professional mechanic to retrieve these codes.
Consult a Professional
If you’ve exhausted all troubleshooting options, it’s time to consult a qualified mechanic or a specialized automotive diagnostic center. They have the expertise and tools to pinpoint the problem and perform any necessary repairs.
“When dealing with scan tool communication issues, it’s important to systematically eliminate the potential causes,” advises Michael Stevens, ASE Certified Master Technician. “Start with the simple checks, like fuses and connections, before moving on to more complex diagnostics.”

Troubleshooting a scan tool not working on your 2014 Traverse can seem daunting, but by following these steps, you can often identify and fix the problem yourself. Remember to check the fuses, the OBD-II port, and your scan tool’s compatibility. If the issue persists, consulting a professional mechanic is always a good option. Don’t let a malfunctioning scan tool keep you in the dark about your vehicle’s health.
