Experiencing issues with your OBD2 port in your 2013 Jeep Wrangler JKU? You’re not alone. Many Jeep owners encounter situations where they need to diagnose problems using an OBD2 scanner, only to find the port unresponsive. One of the first and easiest things to check is the OBD2 fuse location. This guide will help you locate the OBD2 fuse in your 2013 JKU and provide some troubleshooting steps to get your diagnostic port working again.
The OBD2 port, or On-Board Diagnostics port, is crucial for accessing your Jeep’s computer system. It’s used for emissions testing, diagnosing engine problems, and even for performance tuning. If your OBD2 scanner isn’t powering up or connecting when plugged into the port, a blown fuse is a very common culprit. Locating and checking this fuse should be your first step in diagnosing the issue.
In a 2013 Jeep Wrangler JKU, the OBD2 fuse is typically found in the Power Distribution Center (PDC), also known as the fuse box. This fuse box is located under the hood, on the passenger side of the engine compartment, near the battery. To access the fuses, you’ll need to open the PDC cover. The cover usually has labels or a diagram on the underside to help you identify the fuses.

For the 2013 Jku Obd2 Fuse Location specifically, you’ll be looking for a fuse often labeled as “Cigar Lighter” or “Power Outlet”. This might seem counterintuitive, but on many Jeep JK models, the OBD2 port shares a fuse with the cigarette lighter or accessory power outlets. Refer to the fuse box diagram on the underside of the PDC cover or your Jeep owner’s manual to confirm the exact fuse location and amperage for your specific 2013 JKU model. Fuse positions and labels can slightly vary depending on the exact vehicle configuration and options.
Once you’ve located the correct fuse, carefully remove it from the fuse box. Visually inspect the fuse. A blown fuse will often have a broken wire or melted section inside the clear plastic housing. If the fuse looks blown, replace it with a new fuse of the exact same amperage. Using a fuse with a higher amperage can potentially damage your vehicle’s electrical system.

If you replace the fuse and your OBD2 port still isn’t working, or if the fuse blows again immediately, there might be a more serious issue. Possible causes could include a short circuit in the wiring to the OBD2 port or a problem with the OBD2 port itself. In these cases, further diagnosis and repair by a qualified automotive technician might be necessary. They can use specialized tools to test the wiring and the OBD2 port to pinpoint the exact problem.
Checking the 2013 JKU OBD2 fuse location is a simple first step in troubleshooting a non-functional OBD2 port. By following these steps, you can often resolve the issue quickly and get back to diagnosing your Jeep’s systems. Remember to always consult your owner’s manual for the most accurate fuse box diagrams and fuse specifications for your specific 2013 Jeep Wrangler JKU.
