Understanding your 2013 Hyundai Elantra’s fuse box is crucial for maintaining its electrical system. If you’re experiencing issues with your car’s accessories or systems, checking the fuses should be one of your first steps. This guide will specifically focus on the 2013 Hyundai Elantra Obd2 Fuse Location and provide a detailed overview of all fuse box locations, helping you diagnose and resolve electrical problems efficiently.
Locating the Fuse Boxes in Your 2013 Hyundai Elantra
For the 2013 Hyundai Elantra, you’ll find the primary fuses in two main locations: the interior fuse box, situated under the dashboard, and the engine compartment fuse box. Knowing both locations is essential for a complete understanding of your vehicle’s fuse system.
Interior Fuse Box Location (Under the Dashboard)
The interior fuse box in your 2013 Hyundai Elantra is conveniently located beneath the driver’s side dashboard. This location is easily accessible and houses fuses that control many of the car’s interior electrical components, including lights, power outlets, and certain electronic modules.
To access this fuse box:
- Locate the panel beneath the steering wheel, on the driver’s side.
- You may need to kneel down and look upwards to see it clearly.
- The fuse box cover usually has a diagram on it, or it may be a simple plastic cover that you can pull off.
Once you’ve located and opened the interior fuse box, you’ll see an arrangement of fuses and relays. Refer to the fuse diagram (often found on the inside of the fuse box cover or in your owner’s manual) to identify the specific fuse you need to check related to your issue, including potential fuses related to the OBD2 system.

Engine Compartment Fuse Box Location
The second fuse box in your 2013 Hyundai Elantra is located in the engine compartment. This fuse box typically houses fuses and relays that protect more critical vehicle systems, such as the engine control unit (ECU), anti-lock braking system (ABS), and cooling fan.
To find the engine compartment fuse box:
- Open the hood of your Hyundai Elantra.
- Locate a black plastic box, usually near the battery or engine bay side panel.
- It will have a cover that is typically secured by clips or tabs.
After opening the engine compartment fuse box, you’ll find another set of fuses and relays. Again, consult the fuse diagram to locate the specific fuse you need to inspect. This fuse box is less likely to contain a fuse directly labeled “OBD2,” but it houses fuses for systems that are crucial for OBD2 diagnostics to function, such as the ECU/PCM.

Understanding the OBD2 System and Fuses
While there isn’t typically a fuse explicitly labeled “OBD2” in your 2013 Hyundai Elantra, the On-Board Diagnostics system (OBD2) relies on the car’s computer (PCM/ECM) and related sensors to function. Therefore, fuses that protect the Powertrain Control Module (PCM) or Engine Control Module (ECM) are indirectly crucial for OBD2 operation.
If you are experiencing issues with your OBD2 scanner not connecting or not reading data from your 2013 Hyundai Elantra, check the following fuses in both fuse boxes:
- ECU-related fuses: Look for fuses labeled “ECU,” “PCM,” or “ECM” in both fuse box lists. In the engine compartment, “ECU 3” and “ECU 4” are relevant. In the interior fuse box, “IG1” feeds power to ECU related fuses in the engine bay.
- Power fuses: The OBD2 port needs power to operate. Check fuses related to the instrument panel or general module power, as these might affect the OBD2 port’s power supply. “IG1” and “IG2” in both fuse boxes are important to consider.
- Sensor fuses: Since OBD2 relies on sensor data, fuses protecting sensors (like “SENSOR 1” and “SENSOR 2” in the engine bay fuse box) can also indirectly impact OBD2 functionality if a sensor circuit is interrupted by a blown fuse.

How to Check for a Blown Fuse
Identifying a blown fuse is a straightforward process:
- Visual Inspection: Remove the fuse from the fuse box. Hold it up to the light and look at the thin wire inside the fuse.
- Check for a Broken Wire: If the wire is broken or melted, the fuse is blown and needs replacement. Sometimes, the fuse might also have a dark or burnt appearance inside.

Replacing a Fuse in Your 2013 Hyundai Elantra
When replacing a blown fuse:
- Use the Correct Fuse Type and Rating: Refer to the fuse diagram to determine the correct fuse amperage (rating) for the circuit. Using a fuse with a higher rating can damage the electrical system. Hyundai Elantras typically use blade-type mini fuses.
- Remove the Blown Fuse: Use a fuse puller (often found in one of the fuse boxes) or needle-nose pliers to gently remove the blown fuse.
- Install a New Fuse: Push the new fuse firmly into the fuse slot.
- Test the Circuit: After replacing the fuse, test the affected component to ensure it is working correctly. If the new fuse blows immediately, there might be a more significant electrical issue requiring professional diagnosis.

Frequently Asked Questions about Hyundai Elantra Fuses
Where are the fuse boxes located in my 2013 Hyundai Elantra?
Your 2013 Hyundai Elantra has two main fuse box locations:
- Inside the car, under the dashboard on the driver’s side.
- In the engine compartment, typically near the battery.
How can I tell if a fuse is blown?
Visually inspect the fuse. If the thin wire inside is broken or melted, or if there’s a dark mark inside the fuse, it’s likely blown.
What is the cost of replacing a fuse?
A single fuse is inexpensive, usually costing between $10 and $20 if you replace it yourself. If you go to a dealership, the cost could be around $100, often due to labor charges and diagnostics.
