How to Reset TPMS on Your Subaru Crosstrek Quickly and Easily
Subaru Crosstrek TPMS reset and relearn guide covers all generations. Learn when and how to reset or relearn TPMS sensors, troubleshoot issues, and maintain optimal tire performance for safety and efficiency.<>
The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, including the Subaru Crosstrek. It alerts drivers when tire pressure is low, helping to prevent accidents and improve fuel efficiency. However, there are times when you may need to reset or relearn the TPMS, such as after rotating tires or replacing sensors. This comprehensive guide will walk you through the process for all generations of the Subaru Crosstrek.<>
Understanding TPMS in Subaru Crosstrek
Before diving into the reset and relearn procedures, it’s important to understand how the TPMS works in Subaru Crosstrek models:<>
- Subaru uses a direct TPMS, meaning each wheel has its own sensor.
- The system monitors tire pressure and temperature, sending data to the vehicle’s computer.
- When pressure drops below a certain threshold, the TPMS light illuminates on the dashboard.
- The TPMS light looks like a horseshoe or semi-circle with an exclamation point inside.
When to Reset or Relearn TPMS
You may need to reset or relearn the TPMS in the following situations:<>
- After rotating tires
- When replacing one or more TPMS sensors
- After swapping between summer and winter tires
- If the TPMS light remains on after properly inflating tires
TPMS Reset vs. Relearn
It’s crucial to understand the difference between resetting and relearning:<>
- Reset: Simply turning off the TPMS light after addressing low tire pressure.
- Relearn: Teaching the vehicle’s computer to recognize new sensor positions or IDs.
TPMS Reset Procedure for Subaru Crosstrek
First Generation Crosstrek (2013-2017)
For the first-generation Crosstrek, there is no dedicated TPMS reset button. Follow these steps:<>
- Ensure all tires are properly inflated to the recommended pressure.
- Drive the vehicle for about 10-20 minutes at speeds above 20 mph.
- The TPMS light should turn off automatically once the system recognizes the correct pressures.
If the light doesn’t turn off, you may need to perform a relearn procedure or have the system checked by a professional.<>
Second Generation Crosstrek (2018-present)
The process for the second-generation Crosstrek is similar:<>
- Inflate all tires to the proper pressure.
- Drive the vehicle for about 20 minutes at various speeds.
- The system should automatically reset and turn off the TPMS light.
TPMS Relearn Procedure for Subaru Crosstrek
The relearn procedure is more complex and typically requires special tools. Here’s a general overview of the process:<>
All Generations
- Obtain a TPMS relearn tool. Popular options include the Autel MaxiTPMS TS401 and the ATEQ TPMS QuickSet.
- Ensure the vehicle is in “accessory” mode (power on, engine off).
- Use the TPMS tool to read and record the sensor IDs for each wheel.
- Connect the TPMS tool to the vehicle’s OBD-II port.
- Follow the tool’s instructions to write the new sensor IDs to the vehicle’s computer.
- Start the engine and check that the TPMS light turns off after a few minutes of driving.
Important Notes
- The exact steps may vary depending on the specific TPMS tool you’re using.
- Some tools may require you to trigger each sensor in a specific order (usually starting with the driver’s front tire and moving clockwise).
- Subaru does not provide a way to relearn TPMS sensors without specialized equipment.
Professional TPMS Service
If you’re not comfortable performing the relearn procedure yourself, or if you don’t have access to the necessary tools, it’s best to seek professional help:<>
- Most tire shops and Subaru dealerships can perform TPMS resets and relearns.
- The cost typically ranges from $50 to $100 for a TPMS relearn service.
- Professional service ensures the job is done correctly and can diagnose any underlying issues with the TPMS system.
Troubleshooting TPMS Issues
If you’re experiencing persistent TPMS problems, consider the following:<>
TPMS Light Flashing
If the TPMS light flashes for about 60 seconds before staying solid, this indicates a system malfunction rather than a simple pressure issue. In this case:<>
- Have the system checked by a professional.
- There may be a faulty sensor or other electrical issue.
Sensor Battery Life
TPMS sensors have batteries that typically last 5-7 years. If your Crosstrek is approaching this age:<>
- Consider having the sensors checked or replaced.
- Failing sensors can cause persistent TPMS warnings.
Temperature Effects
Extreme temperature changes can affect tire pressure and trigger the TPMS light. In these cases:<>
- Check and adjust tire pressure when tires are cold (vehicle hasn’t been driven for at least 3 hours).
- Remember that for every 10°F change in temperature, tire pressure can change by about 1 PSI.
Maintaining Your TPMS
To keep your Subaru Crosstrek’s TPMS functioning properly:<>
- Check tire pressure monthly, including the spare tire (if equipped).
- Have TPMS sensors checked during routine tire services.
- Be cautious when using tire sealants, as they can damage TPMS sensors.
- When replacing tires, ensure new TPMS sensors are installed if the old ones are nearing the end of their lifespan.
TPMS and Seasonal Tire Changes
Many Subaru Crosstrek owners switch between summer and winter tires. Here are some considerations:<>
- If using a second set of wheels, consider purchasing a second set of TPMS sensors.
- Some aftermarket TPMS tools allow you to store multiple sensor sets, making seasonal swaps easier.
- Always perform a TPMS relearn after swapping wheel sets.
Understanding TPMS Regulations
It’s important to note that TPMS is not just a convenience feature, but a legal requirement in many countries:<>
- In the United States, TPMS has been mandatory on all new vehicles since 2007.
- Disabling the TPMS system is illegal and can compromise vehicle safety.
- When replacing TPMS sensors, ensure they meet the required specifications for your vehicle.
Conclusion
Properly maintaining and understanding your Subaru Crosstrek’s TPMS is crucial for safety and optimal vehicle performance. While simple resets can often be done at home, more complex relearn procedures may require specialized tools or professional assistance. Always consult your vehicle’s manual and don’t hesitate to seek professional help if you’re unsure about any aspect of TPMS maintenance or repair.<>
FAQs
Q: Can I drive with the TPMS light on?
A: While you can drive short distances, it’s best to check your tire pressures as soon as possible. Driving on underinflated tires can be dangerous and cause damage.<>
Q: Will the TPMS work if I use aftermarket wheels?
A: Yes, as long as you transfer the TPMS sensors to the new wheels or install new compatible sensors.<>
Q: How accurate is the TPMS in my Subaru Crosstrek?
A: TPMS sensors are generally quite accurate, but it’s still a good idea to check your tire pressures manually on a regular basis.<>
Q: Can extreme cold weather affect my TPMS?
A: Yes, cold weather can cause tire pressure to drop, potentially triggering the TPMS light. Always check pressures when tires are cold during winter months.<>
Q: Do I need to reset the TPMS after every tire rotation?
A: For most Subaru Crosstrek models, a reset isn’t necessary after rotation unless you’re experiencing issues. However, it’s a good practice to monitor the system closely after any tire service.<>
