Quick Answer
If your 2012 Hyundai Accent's speedometer stopped working after installing a new radio, it's likely due to a disconnected or disturbed connection.
Quick fix:
- Check the wiring, as the speed sensor wire might have been disconnected during the install.
- Ensure all connections are secured and there are no loose wires behind the dash.
For a quick start, inspect the fuse box. A blown fuse related to the dash or instrument panel could also be the culprit. Look for:
- The fuse labeled "Instrument Cluster" or similar.
- Replace any blown fuses with one of the same amperage.
Summary: Radio installs can disrupt nearby systems. Double-check wiring, secure connections, and inspect fuses. This should help resolve most speedometer issues post-install.

Experiencing an issue with your speedometer becoming inoperative after installing a new radio in your 2012 Hyundai Accent can be a frustrating problem, but don't worry—let's dive into some potential reasons and solutions!
Firstly, when installing aftermarket radios, it's common to inadvertently affect other electrical components. The speedometer, in many vehicles, relies on a series of electrical signals and sensors, all of which are part of the vehicle's complex wiring system.
One of the most straightforward explanations and solutions for this issue involves checking the fuse box. The problem could be due to a blown fuse, especially if wires or other components were disturbed during installation.
Fuse Box Location
In the 2012 Hyundai Accent, there are typically two fuse boxes:
- Interior Fuse Box: Located on the driver's side of the cabin, look beneath the dashboard, near the steering wheel. You might need to remove a cover panel to access it.
- Engine Compartment Fuse Box: Found under the hood, it's usually on the driver's side, near the battery or the side fender. Lift up the cover to access the fuses.
Fuse Diagram and Tables
You'll want to refer to the fuse box diagrams typically located on the fuse box cover itself. However, I'll provide some basic guidance here:
Interior Fuse Box
| Fuse | Function |
|---|---|
| 10A | Instrument Panel, including Speedometer |
| 15A | Radio, Audio System |
Engine Compartment Fuse Box
| Fuse | Function |
|---|---|
| 20A | Main Ignition System |
| 30A | Engine Management Systems |
Steps to Diagnose and Fix
- Begin by checking the interior fuse box to see if the instrument panel fuse (often 10A) is blown. Replace it with the same amperage rating if needed.
- If the instrument panel fuse is fine, check the connections made during the radio installation, especially any wires that might connect to the vehicle’s system data bus.
- Inspect wiring harnesses; ensure no pins are bent or damaged, and confirm that all connectors are secure.
- If the problem persists, explore the engine compartment fuse box and check relevant fuses.
By following these steps and understanding where critical fuses and components lie, you should be able to restore your speedometer functionality. Happy troubleshooting!
