These instructions apply to the Kia Rio (UB, QBR) 2011 - 2018. For other models, please choose your vehicle here.
The Kia Rio (2011–2018) is equipped with an OBD-II diagnostic port that allows you to read engine fault codes, reset warning lights, and monitor live data using a scan tool. This guide shows where to find the connector and how to access it safely without removing interior trim.
OBD-II Port Location
The diagnostic connector is located under the dashboard on the driver’s side, just above the brake pedal and to the left of the steering column. It sits behind a small plastic trim section integrated into the lower dash panel.
How to Access the Connector
- Sit in the driver’s seat and look under the steering column toward the pedals.
- Locate the 16-pin trapezoidal connector facing downward or slightly toward the rear.
- If covered, gently pull open the small access panel or trim flap.
- Insert your diagnostic scanner’s plug — it only fits one way, so do not force it.
Connector Pinout (Overview)
- Pin 16: +12 V battery power
- Pins 4 & 5: Ground
- Pins 6 & 14: CAN communication lines
Tips for Safe Use
- Keep the ignition ON (engine off) when connecting a scan tool unless otherwise specified.
- Never connect or disconnect the tool during engine cranking.
- If the connector feels loose or misaligned, support it with your hand before inserting the plug.
- After diagnostics, ensure the connector is left uncovered but protected from dirt or moisture.
Recommended Tools
- Bluetooth or Wi-Fi OBD-II adapter compatible with Android/iOS apps such as Torque or Car Scanner.
- Professional handheld scanner for reading live data and clearing DTCs.
