How to Reset and Relearn the TPMS of Toyota 86 in All Generations
The Toyota 86, also known as the GT86, FT86, and Subaru BRZ, is a popular sports car that has been in production since 2012. One important safety feature of this vehicle is its Tire Pressure Monitoring System (TPMS). Understanding how to properly reset and relearn the TPMS is crucial for maintaining optimal tire performance and safety. This comprehensive guide will walk you through the process for all generations of the Toyota 86.<>
Understanding TPMS in the Toyota 86
Before diving into the reset and relearn procedures, it’s important to understand what TPMS is and how it functions in the Toyota 86.<>
What is TPMS?
TPMS is a safety feature that monitors the air pressure in a vehicle’s tires. It alerts the driver when one or more tires are significantly under-inflated, potentially creating unsafe driving conditions. In the Toyota 86, this system uses sensors located in each tire to transmit pressure data to the vehicle’s computer.<>
Types of TPMS in Toyota 86
The Toyota 86 uses a direct TPMS, which means it has individual sensors in each tire. These sensors directly measure the air pressure and temperature inside the tire and transmit this data to the vehicle’s TPMS module.<>
When to Reset or Relearn TPMS
There are several situations when you might need to reset or relearn the TPMS in your Toyota 86:<>
- After rotating tires
- When replacing one or more tires
- After replacing a TPMS sensor
- When the TPMS warning light remains on after inflating tires to the correct pressure
- When switching between summer and winter tire sets
TPMS Reset vs. Relearn
It’s important to understand the difference between resetting and relearning the TPMS:<>
TPMS Reset
A TPMS reset is a simple procedure that can be done by the driver. It typically involves pressing a button to clear the TPMS warning light after adjusting tire pressures. This process does not reprogram the system or teach it new sensor IDs.<>
TPMS Relearn
A TPMS relearn is a more complex procedure that involves teaching the vehicle’s TPMS module to recognize new sensor IDs. This is necessary when replacing sensors or switching to a different set of wheels with their own sensors.<>
TPMS Reset Procedure for Toyota 86 (All Generations)
The TPMS reset procedure is relatively simple and consistent across all generations of the Toyota 86. Here’s how to do it:<>
- Ensure all tires are inflated to the correct pressure as specified in your owner’s manual or on the driver’s side door jamb sticker.
- Turn the ignition to the “ON” position without starting the engine.
- Locate the TPMS reset button. In the Toyota 86, this is typically found in the glove compartment.
- Press and hold the TPMS reset button until the TPMS warning light blinks three times.
- Release the button and start the engine.
- Drive the vehicle for about 20 minutes at speeds above 25 mph to complete the reset process.
If the TPMS light doesn’t turn off after this procedure, you may need to perform a TPMS relearn or have your system checked by a professional.<>
TPMS Relearn Procedure for Toyota 86 (First Generation: 2012-2021)
The first generation Toyota 86 requires a specific tool and procedure for TPMS relearn. Here’s how to do it:<>
Tools Required
- TPMS relearn tool (such as ATEQ QuickSet or similar OBD2-compatible TPMS tool)
- TPMS sensor activation tool (if sensors need to be manually activated)
Procedure
- Obtain the sensor IDs for all four tires. These are usually on a sticker on the sensor, or you can use a TPMS activation tool to read them.
- Connect your TPMS relearn tool to the vehicle’s OBD2 port.
- Follow the tool’s instructions to enter the programming mode for the Toyota 86.
- Input the sensor IDs for each tire in the correct order (usually LF, RF, RR, LR).
- Confirm the new sensor IDs have been programmed into the vehicle’s TPMS module.
- Disconnect the tool and start the engine.
- Drive the vehicle for about 20 minutes at speeds above 25 mph to ensure the system recognizes all sensors.
TPMS Relearn Procedure for Toyota GR86 (Second Generation: 2022-Present)
The second generation Toyota GR86 uses a similar TPMS to the first generation, but the relearn procedure may vary slightly depending on the specific model year and region. Here’s a general guide:<>
Tools Required
- TPMS relearn tool compatible with the latest Toyota models
- TPMS sensor activation tool (if needed)
Procedure
- Ensure all tires are inflated to the correct pressure.
- Turn the ignition to the “ON” position without starting the engine.
- Connect your TPMS relearn tool to the OBD2 port.
- Follow the tool’s instructions to enter the TPMS relearn mode for the GR86.
- The tool will guide you through the process of reading and programming the new sensor IDs.
- Once complete, disconnect the tool and start the engine.
- Drive the vehicle for about 20 minutes to ensure all sensors are recognized.
Troubleshooting TPMS Issues in Toyota 86
If you’re experiencing persistent TPMS issues with your Toyota 86, consider the following troubleshooting steps:<>
TPMS Light Stays On
- Check tire pressures and adjust if necessary
- Perform a TPMS reset
- Check for faulty TPMS sensors
- Verify that the correct TPMS sensor IDs are programmed into the vehicle
TPMS Light Flashes
A flashing TPMS light typically indicates a system malfunction. Possible causes include:<>
- Failed TPMS sensor
- Low sensor battery
- TPMS module malfunction
In these cases, it’s best to have the system diagnosed by a professional.<>
Maintaining Your Toyota 86’s TPMS
To keep your TPMS functioning properly, follow these maintenance tips:<>
- Regularly check and maintain proper tire pressure
- Have TPMS sensors checked during routine tire services
- Replace TPMS sensor batteries when they’re low (typically every 5-7 years)
- Be cautious when mounting or dismounting tires to avoid damaging the sensors
TPMS and Aftermarket Wheels
If you’re considering aftermarket wheels for your Toyota 86, keep these TPMS considerations in mind:<>
- Ensure the new wheels are compatible with your existing TPMS sensors
- If new sensors are required, make sure they’re compatible with your vehicle’s TPMS
- After installing new wheels and sensors, a TPMS relearn will be necessary
TPMS and Track Days
For Toyota 86 owners who participate in track days or racing events, it’s important to note that extreme heat generated during high-performance driving can affect TPMS sensors. Consider these tips:<>
- Check sensor functionality before and after track sessions
- Be prepared to perform a TPMS reset or relearn if needed
- Consider using a separate set of wheels without TPMS for track use
Legal Requirements for TPMS
TPMS has been mandatory on all new passenger vehicles in many countries since the mid-2000s. For example:<>
- United States: Required on all vehicles manufactured after September 1, 2007
- European Union: Mandatory on all new cars since November 1, 2014
- Japan: Required on all new vehicles since 2018
It’s important to maintain a functioning TPMS not only for safety but also to comply with these regulations.<>
TPMS Technology Advancements
As automotive technology continues to advance, TPMS systems are also evolving. Some recent and upcoming developments include:<>
- Integration with vehicle telematics systems for remote tire pressure monitoring
- Advanced sensors that can detect tire wear and alignment issues
- Self-inflating tire systems that work in conjunction with TPMS
While these features may not be present in current Toyota 86 models, they could appear in future generations or high-end trims.<>
Frequently Asked Questions
To address common concerns about TPMS in the Toyota 86, here are answers to some frequently asked questions:<>
