The Toyota GR Supra is a high-performance sports car that demands optimal tire performance for safety and handling. An essential component of tire maintenance is the Tire Pressure Monitoring System (TPMS), which alerts drivers to potential tire pressure issues. In this comprehensive guide, we’ll explore how to reset and relearn the TPMS for all generations of the Toyota GR Supra, ensuring your vehicle maintains peak performance and safety.
Understanding TPMS in Toyota GR Supra
The Tire Pressure Monitoring System is a crucial safety feature that continuously monitors tire pressure and alerts the driver when it falls below the recommended level. For the Toyota GR Supra, maintaining proper tire pressure is not just about safety, but also about optimizing performance and handling.
Why TPMS Reset and Relearn is Important
Resetting and relearning the TPMS is necessary in several situations:
- After rotating tires
- When replacing one or more tires
- After installing new TPMS sensors
- When the TPMS warning light remains on after adjusting tire pressure
Proper TPMS function ensures that you’re getting the most out of your Supra’s performance capabilities while maintaining safety on the road.
TPMS Reset and Relearn Process for Toyota GR Supra (A90/J29 Generation, 2019-Present)
The current generation of the Toyota GR Supra, known as the A90 or J29, uses a direct TPMS system. Here’s how to reset and relearn the TPMS for this model:
Method 1: Using the iDrive System
- Ensure all tires are inflated to the correct pressure (38 PSI when cold for stock tires)
- Turn on the ignition without starting the engine
- Navigate to the vehicle settings in the iDrive system
- Select “Vehicle status”
- Choose “Perform reset”
- Follow the on-screen prompts to complete the reset process
- Start the engine and drive the vehicle
- The system will automatically relearn the new tire pressures and sensor positions during the drive
Method 2: Automatic Relearn
For the latest GR Supra models, the TPMS is designed to automatically relearn new sensor positions:
- Ensure all tires are properly inflated
- Drive the vehicle for about 10-20 minutes at speeds over 25 mph
- Include some turns and curves in your drive to help the system identify sensor positions
The TPMS should automatically recalibrate and clear any warning lights after this process.
TPMS Reset for Older Supra Models (A80 Generation and Earlier)
While the original Supra models (A40, A60, A70, and A80) did not come equipped with TPMS from the factory, some may have had aftermarket systems installed. For these cases, the reset process will depend on the specific aftermarket system. Generally, it may involve:
- Locating a TPMS reset button, often under the steering wheel or in the glove compartment
- Pressing and holding the reset button until the TPMS light flashes three times
- Releasing the button and starting the engine
- Driving the vehicle for about 20 minutes to complete the relearn process
Using TPMS Tools for Advanced Reset and Relearn
For more complex situations or when dealing with aftermarket wheels and sensors, professional TPMS tools may be necessary. These tools can program new sensors and force the vehicle’s system to relearn sensor positions.
Programming Universal Sensors
- Use a compatible TPMS tool (e.g., Autel, OTC, or Snap-On scanner)
- Select the appropriate vehicle make, model, and year
- Choose the “Program Sensor” option
- Follow the tool’s prompts to program each new sensor
- Use the tool to trigger each sensor and record the ID numbers
Cloning Existing Sensor IDs
For a seamless transition when replacing sensors:
- Use the TPMS tool to read the existing sensor ID
- Select the “Clone” or “Copy” function on the tool
- Program the new sensor with the copied ID
- Install the new sensor in the tire
This method ensures that the vehicle’s TPMS module continues to recognize the sensor without requiring a system reset.
Troubleshooting TPMS Issues in Toyota GR Supra
If you encounter persistent TPMS problems, consider the following troubleshooting steps:
- Check for damaged or corroded TPMS sensors
- Verify that all sensors are compatible with your Supra model
- Ensure the vehicle’s TPMS module is functioning correctly
- Look for interference from other electronic devices
If issues persist, consult a Toyota dealership or a certified TPMS specialist for advanced diagnostics and repair.
Best Practices for TPMS Maintenance in Toyota GR Supra
To keep your Supra’s TPMS functioning optimally:
- Regularly check tire pressure when tires are cold
- Rotate tires according to the manufacturer’s schedule
- Replace TPMS sensors when replacing tires, or at least every 5-7 years
- Use high-quality, compatible sensors when replacements are needed
- Have your TPMS checked during routine maintenance visits
The Importance of Correct Tire Pressure in the GR Supra
Maintaining the correct tire pressure is crucial for the GR Supra’s performance and safety. The recommended pressure for stock tires is 38 PSI when cold. Proper inflation ensures:
- Optimal handling and cornering performance
- Improved fuel efficiency
- Even tire wear
- Maximum traction for acceleration and braking
TPMS and Track Day Considerations
For Supra owners who enjoy track days, it’s important to note that tire pressures may need adjustment for optimal performance on the track. However, this can trigger TPMS warnings. Consider the following:
- Adjust tire pressures for track use according to expert recommendations
- Be prepared to reset the TPMS after track sessions
- Consider using a separate set of wheels and tires for track use to avoid frequent TPMS resets
Future of TPMS Technology in Toyota Vehicles
As automotive technology advances, TPMS systems are likely to become more sophisticated. Future Toyota models, including potential new Supra generations, may feature:
- Integration with advanced driver assistance systems (ADAS)
- Predictive tire wear analysis
- Automatic tire pressure adjustment systems
- Enhanced smartphone integration for tire monitoring
Conclusion
Proper maintenance and understanding of your Toyota GR Supra’s TPMS are essential for both safety and performance. By following the reset and relearn procedures outlined in this guide, you can ensure that your TPMS functions correctly, providing accurate tire pressure information at all times. Remember that while these procedures are generally straightforward, if you encounter any difficulties or are unsure about any step, it’s always best to consult with a professional Toyota technician or TPMS specialist.
Keep your Supra’s tires properly inflated and its TPMS system in top condition, and you’ll continue to enjoy the exhilarating performance and handling that make the GR Supra a true driver’s car.
