Imagine this: You’re cruising down the Pacific Coast Highway in your luxurious 2011 Infiniti QX56, the California sun warming your face. Suddenly, the “Check Engine” light throws a wrench in your road trip plans. You pull over, pull out your trusty OBD scanner, and…nothing. No power. Could it be the OBD fuse? Don’t panic! Finding and replacing the OBD fuse in your QX56 is a relatively simple task, even for those who aren’t mechanically inclined.
Decoding the Mystery of the OBD Fuse
Before we dive in, let’s understand why this little fuse is so important.
The Vital Role of the OBD Fuse
The OBD, or On-Board Diagnostics, port is your car’s communication hub. It allows you to connect diagnostic tools, like code readers, to understand what’s happening under the hood. The OBD fuse acts as a safety guard for this system. If there’s an electrical surge, the fuse blows, protecting the more expensive components.
Common Signs of a Blown OBD Fuse
- Your OBD scanner doesn’t power on.
- Other electrical systems in your car might be acting up, as the OBD fuse might be on a shared circuit.
Locating the Elusive OBD Fuse in Your 2011 Infiniti QX56
The OBD fuse location can vary slightly between car models. However, for the 2011 Infiniti QX56, you’ll likely find it in one of these two places:
- The Fuse Panel on the Driver’s Side: This panel is usually located on the side of the dashboard, behind a cover.
- The Fuse Box Under the Hood: This box is often near the battery and will have a diagram on its lid showing the location of each fuse.

Identifying the Correct Fuse
Once you’ve located the fuse panel, consult your owner’s manual. It will have a detailed diagram and a list of each fuse’s function, including the OBD fuse. The fuse itself is usually small and either brown or clear, with a metal strip visible inside.
“Always refer to your owner’s manual for the most accurate information regarding fuse locations and amperage,” advises Michael Carter, an experienced automotive electrician and author of “The Complete Guide to Automotive Electrical Systems”. “Using the incorrect fuse can lead to further electrical issues.”
Replacing the Fuse: A Step-by-Step Guide
- Turn off your engine and remove the key from the ignition. Safety first!
- Using the fuse puller tool (usually located within the fuse box), carefully remove the suspected blown OBD fuse.
- Examine the fuse. If the metal strip inside is broken, it’s blown and needs replacing.
- Insert a new fuse with the same amperage rating. This information is printed on the fuse itself or in your owner’s manual.
- Replace the fuse box cover.

FAQs About Infiniti QX56 OBD Fuse Issues
Q: Can I drive my QX56 with a blown OBD fuse?
A: Yes, you can technically drive with a blown OBD fuse, but it’s not recommended. The OBD system primarily aids in diagnostics, so your car should function normally.

Q: I replaced the OBD fuse, but it blew again. What could be wrong?
A: A repeatedly blowing fuse usually indicates a short circuit somewhere in the system. This requires professional diagnosis and repair.
Q: Can I replace the OBD fuse myself, or do I need to go to a mechanic?
A: Replacing the OBD fuse is a straightforward task you can likely handle yourself. However, if you’re unsure or uncomfortable working with electrical components, it’s always best to seek professional help.
