Solution

Resetting the Tire Pressure Monitoring System (TPMS) in a 2020 Toyota Highlander is a straightforward process. Below are the symptoms, tools required, diagnostic steps, and detailed instructions for resetting the TPMS.

Tools Required

Tire pressure gauge (for checking tire pressures)
Air compressor (if tire pressure needs adjustment)
Vehicle key fob or key (to start the ignition)

Reset Instructions

Prepare the Vehicle:
- Ensure all tires are properly inflated to the recommended pressure.
- Start your vehicle by inserting the key fob in the ignition and turning it to the "ON" position without starting the engine.
Locate the TPMS Reset Button:
- The TPMS reset button is typically located beneath the steering wheel, near the dashboard. It may also be in the glove box or the center console. Consult the owner’s manual if you have difficulty locating it.
Press the Reset Button:
- Press and hold the TPMS reset button until the TPMS light blinks three times, then release the button.
- The TPMS light should remain illuminated for a short period and then turn off, indicating that the system is recalibrating.
Drive the Vehicle:
- After resetting, drive the vehicle at speeds above 25 mph for about 10-30 minutes. This allows the TPMS to recalibrate and recognize the new tire pressures.
Check for Warning Light:
- If the TPMS warning light remains on after driving, double-check tire pressures and make sure they are at the correct levels.
- If the light persists, there may be a malfunction in the TPMS, and you may need to consult a professional technician.

Additional Notes

If the TPMS light does not turn off after following the above steps, it’s advisable to have the system checked using a diagnostic tool, as there may be a faulty sensor or other issues.
Always reset the TPMS after changing tires, rotating tires, or adjusting tire pressures.

By following these steps, you should successfully reset the Tire Pressure Monitoring System in your 2020 Toyota Highlander.
