Step-By-Step Guide To Resetting Check Engine Light On Toyota Highlander

Resetting the check engine light on your Toyota Highlander is a relatively simple process. By following these step-by-step instructions, you will be able to clear any fault codes that may be triggering the check engine light. It is important to note that this guide is specifically for Toyota Highlanders, but the process may be similar for other Toyota models.

Ensure You Have A Youcanic Full System Scanner For The Procedure

Before attempting to reset the check engine light, it is essential to have a reliable diagnostic tool. We recommend using the YOUCANIC Full System Scanner, which is capable of reading and clearing fault codes from the On-Board Diagnostics (OBD) system in your Toyota Highlander.

Next, turn the ignition on without starting the engine. This will power up the diagnostic system, allowing the scanner to communicate with it. Follow the instructions provided by the scanner to read and clear the fault codes. The scanner will display a list of fault codes associated with the check engine light. Clear these fault codes by following the prompts on the scanner.

Don’t Clear Fault Codes Without Fixing Underlying Issue

While it may be tempting to clear the fault codes and reset the check engine light without addressing the underlying issue, this is not advisable. The check engine light serves as a warning sign that there is a problem with your vehicle’s engine or emissions system. Clearing the fault codes without fixing the underlying issue can lead to further damage and potentially more expensive repairs in the future. It is best to diagnose and correct the problem before resetting the check engine light.

Resetting Maintenance Reminder Light Instructions

  2. Locate the trip reset button on the instrument panel.
  3. Press and hold the trip reset button until the maintenance reminder light starts flashing.
  4. Release the trip reset button, then immediately press and hold it again.
  5. Hold the trip reset button until the maintenance reminder light turns off.
