Experiencing issues with your OBD2 scanner connecting to your 2010 Pontiac G6 can be frustrating. If you’re getting error messages or no communication at all, before you delve into complex diagnostic procedures, a simple fuse check might just be the solution. Let’s explore how to identify and check the OBD2 fuse on your 2010 Pontiac G6 and what to do if a fuse isn’t the issue.
Locating the OBD2 Fuse in Your 2010 Pontiac G6
The fuse box location can vary slightly depending on the Pontiac G6 trim and options, but for a 2010 model, the primary fuse box is typically located inside the car. You’ll usually find it on the driver’s side, underneath the dashboard. It’s often behind a small access panel on the lower part of the dashboard or kick panel area.

Once you’ve located the fuse box, you’ll need to identify the correct fuse for the OBD2 port, also known as the Diagnostic Link Connector (DLC). Refer to the fuse box diagram, which is usually printed on the inside of the fuse box cover. Look for a fuse labeled “OBD,” “DLC,” “Data Link,” or something similar related to diagnostics or the data communication system. For a 2010 Pontiac G6, this fuse is often a 10-amp or 15-amp fuse.
How to Check the OBD2 Fuse
Checking a fuse is a straightforward process. Here’s what you’ll need to do:
- Access the Fuse Box: Open the fuse box cover as described above.
- Locate the OBD2 Fuse: Use the fuse box diagram to pinpoint the fuse for the OBD2 port.
- Visual Inspection: Carefully remove the fuse. You can usually pull it out with your fingers or use a fuse puller tool, which is often included in the fuse box. Hold the fuse up to the light and inspect the thin wire inside. If the wire is broken or melted, the fuse is blown and needs to be replaced.

- Multimeter Test (Optional but Recommended): For a more definitive check, use a multimeter. Set your multimeter to the continuity setting (it looks like a sound wave symbol or a diode symbol). Place the probes on each of the metal terminals on top of the fuse. If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If there’s no beep or the reading is very high (indicating open circuit), the fuse is blown.
- Replace the Fuse (If Blown): If the fuse is blown, replace it with a new fuse of the exact same amperage. Using a fuse with a higher amperage rating can damage your vehicle’s electrical system.
Beyond the Fuse: Other OBD2 Port Issues
If you’ve checked the OBD2 fuse and it’s not blown, but you’re still experiencing communication errors, the problem might lie elsewhere. Here are a few other potential causes:
- OBD2 Port Malfunction: The OBD2 port itself could be damaged or have corroded pins. Inspect the port for any visible damage or debris.
- Wiring Issues: There could be a break or short in the wiring leading to the OBD2 port. This is more challenging to diagnose and might require professional help.
- Scanner Compatibility: While less likely with standard OBD2 scanners, there’s a slight chance your scanner might not be fully compatible with the 2010 Pontiac G6. Try a different scanner if possible.
- Vehicle Computer Problems: In rare cases, a problem with the vehicle’s computer (PCM or ECM) could prevent OBD2 communication.
When to Seek Professional Help
If you’ve checked the OBD2 fuse and explored other simple fixes but still can’t get your scanner to connect, it’s time to consult a qualified mechanic. Diagnosing electrical issues, especially those related to vehicle communication systems, can be complex and requires specialized tools and expertise. A professional technician can accurately pinpoint the root cause of the OBD2 communication problem on your 2010 Pontiac G6 and perform the necessary repairs.
Checking the 2010 Pontiac G6 Obd2 Fuse is a quick and easy first step in troubleshooting communication issues. While it may not always be the solution, it’s a simple fix that can save you time and money. If the fuse is not the problem, remember to systematically rule out other potential causes before seeking professional diagnostic services.
