Maintaining your 2015 Hyundai Sonata in peak condition requires attention to all its systems, and the Tire Pressure Monitoring System (TPMS) is no exception. Ensuring your TPMS functions correctly is crucial for safety, tire longevity, and fuel efficiency. When a tire pressure sensor is replaced or tires are rotated, a TPMS reset is often necessary. This is where having the right auto scan tool becomes invaluable. This guide will walk you through understanding your 2015 Hyundai Sonata’s TPMS and selecting the best auto scan tool to keep it running smoothly.
Your 2015 Hyundai Sonata is equipped with a sophisticated TPMS that constantly monitors the air pressure in your tires. This system uses wheel-mounted sensors to transmit pressure readings to the vehicle’s computer. If the pressure in one or more tires drops below a specified threshold, the TPMS warning light illuminates on your dashboard, alerting you to a potential issue.

Understanding the TPMS warning light is the first step. However, when you replace a tire pressure sensor, rotate your tires, or even after inflating your tires to the correct pressure after a low pressure warning, the TPMS system may need to be reset or relearned. This is because the system needs to recognize the new sensor IDs or positions. While some vehicles have a simple auto-relearn procedure, many, including the 2015 Hyundai Sonata, benefit from or even require an auto scan tool to expedite or initiate this process.
Why Use an Auto Scan Tool for TPMS Reset on a 2015 Hyundai Sonata?
While the 2015 Hyundai Sonata TPMS receiver has an auto-learn function, it typically requires driving at speeds over 12 mph (20 km/h) for up to 20 minutes. An auto scan tool can significantly shorten this process and offer more control. Here’s why using a scan tool is advantageous:
- Speed and Efficiency: A scan tool can initiate the TPMS relearn procedure much faster than the auto-learn function, saving you time.
- Sensor ID Registration: When replacing sensors, a scan tool can directly register the new sensor IDs to the vehicle’s computer, ensuring proper communication.
- Troubleshooting: Advanced scan tools can also diagnose TPMS issues, read sensor data, and identify potential malfunctions beyond just low pressure.
- Procedure Initiation: For certain TPMS procedures, like sensor mode changes, a scan tool is mandatory, as highlighted in the original Hyundai Sonata (2008-2010) documentation.

Choosing the Right Auto Scan Tool for Your 2015 Hyundai Sonata
Selecting the best auto scan tool depends on your needs and budget. Here are a few categories and considerations for your 2015 Hyundai Sonata TPMS reset:
1. Basic TPMS Reset Tools:
These are entry-level tools primarily designed for TPMS relearn and sensor activation. They are often handheld and affordable, ideal for DIYers or tire shops performing routine TPMS services. Look for tools that specify compatibility with Hyundai vehicles and support the 315MHz or 433MHz frequencies used by Hyundai TPMS sensors.
Features to look for:
- Hyundai Sonata compatibility: Specifically listed as supported vehicle.
- TPMS relearn function: Ability to initiate the TPMS reset procedure.
- Sensor activation: Can trigger sensors to transmit data for relearn.
- Ease of use: Simple interface and clear instructions.
2. Mid-Range OBD2 Scan Tools with TPMS Functions:
These tools offer a broader range of diagnostic capabilities beyond just TPMS. They connect to your 2015 Hyundai Sonata’s OBD2 port and can read trouble codes, access live data, and perform various system resets, including TPMS. These are a great option for car enthusiasts and professional technicians needing more versatility.
Features to look for (in addition to basic tool features):
- OBD2 diagnostic functions: Reading and clearing diagnostic trouble codes (DTCs) for various vehicle systems.
- Live data streaming: Viewing real-time sensor data, including tire pressures.
- Bi-directional control (sometimes): Activating components to test functionality.
- Wider vehicle coverage: Support for multiple makes and models, not just Hyundai.
3. Professional-Grade Diagnostic Scan Tools:
These are advanced, comprehensive scan tools used by professional automotive technicians. They offer the most extensive TPMS functionality, along with in-depth diagnostics for all vehicle systems. While more expensive, they provide the most thorough and efficient TPMS service and vehicle diagnostics.
Features to look for (in addition to mid-range tool features):
- Advanced TPMS functions: Sensor programming, ECU coding, detailed system diagnostics.
- Comprehensive vehicle system coverage: Diagnostics for engine, transmission, ABS, airbags, and more.
- Regular updates: Software updates to support new vehicles and features.
- Technical support: Access to professional support and resources.

TPMS Reset Procedure for 2015 Hyundai Sonata with a Scan Tool (General Steps):
While specific steps may vary depending on the scan tool and model, here’s a general outline of the TPMS reset procedure for a 2015 Hyundai Sonata using a scan tool:
- Prepare the vehicle: Ensure the vehicle is parked safely and the ignition is off.
- Connect the scan tool: Plug the scan tool into the OBD2 port, typically located under the dashboard on the driver’s side.
- Power on and identify vehicle: Turn the ignition to the “ON” position (engine off) and power on the scan tool. Select “Hyundai” and then “Sonata” and the 2015 model year from the tool’s menu.
- Navigate to TPMS functions: Locate the TPMS or Tire Pressure Monitoring System section within the scan tool’s menu.
- Initiate TPMS Relearn/Reset: Select the “TPMS Relearn” or “Sensor Relearn” function.
- Follow on-screen instructions: The scan tool will provide step-by-step instructions, which may involve activating each sensor using the tool or driving the vehicle briefly.
- Sensor Activation (if required): Some tools require you to activate each sensor individually using a built-in exciter or a separate TPMS activation tool. Follow the tool’s prompts to do this in the correct order (typically front left, front right, rear right, rear left).
- Complete the relearn process: Allow the scan tool to complete the relearn procedure. The tool will typically display a confirmation message upon successful completion.
- Verify TPMS light: After the procedure, ensure the TPMS warning light is off.
- Test drive (if prompted): Some tools may require a short test drive to finalize the relearn process.
Important Notes:
- Consult your scan tool manual: Always refer to the specific instructions provided with your auto scan tool for the most accurate procedure.
- Tire pressure adjustment: Ensure all tires are inflated to the correct pressure specified on your tire placard (usually found on the driver’s side doorjamb) before initiating the TPMS reset.
- Professional assistance: If you are unsure about any step or encounter issues, consult a qualified automotive technician.
