Solution

Resetting the Tire Pressure Monitoring System (TPMS) in a 2021 Toyota Highlander can be necessary after adjusting tire pressures or replacing tires. Below is a detailed guide on how to properly reset the TPMS.

Tools Required

Tire pressure gauge (optional, for verifying tire pressures)
Air compressor (if tire pressures need adjustment)
Vehicle owner’s manual (for reference, if needed)

Repair Instructions

Adjust Tire Pressures:
- If any tires are found to be below the recommended pressure, inflate them to the proper level.
- If any tires are over-inflated, release air until the pressure matches the recommended level.
Turn on the Ignition:
- Insert the key fob into the ignition slot or press the start button without pressing the brake pedal to turn on the electrical system (but do not start the engine).
Locate the TPMS Reset Button:
- The TPMS reset button is usually located beneath the steering wheel or to the right of the steering column. Refer to your owner's manual for the exact location.
Press and Hold the TPMS Reset Button:
- Press and hold the TPMS reset button until the TPMS indicator light on the dashboard blinks three times.
- Release the TPMS reset button.
Wait for Completion:
- Leave the ignition in the ON position for about 3 minutes.
- The TPMS light should turn off, indicating that the system has been reset successfully.
Start the Engine:
- Start the engine and let it run for a few minutes. Drive the vehicle for a short distance to ensure that the TPMS system recalibrates and monitors the tire pressures accurately.
Verify Functionality:
- After driving, check if the TPMS warning light remains off. If the light reappears, repeat the process and ensure that all tire pressures are correct.

Additional Notes

If the TPMS warning light continues to stay on after resetting, there may be an issue with the TPMS sensors or other components within the system. In such cases, a diagnostic scan may be needed to identify any fault codes.
Consider consulting a professional technician if you are uncertain about any steps or if the problem persists.

By following the above steps, you should be able to successfully reset the TPMS in your 2021 Toyota Highlander.
