To reset the check engine light on a 2002 Toyota Highlander, you can disconnect the negative battery terminal for about 15 minutes to clear the codes. Alternatively, you can use an OBD-II scanner to erase the trouble codes directly. After reconnecting the battery or using the scanner, the check engine light should turn off. However, ensure that any underlying issues causing the light to activate are addressed to prevent it from coming back on.
