Alternatively, you can use an OBD2 scanner to reset the timing belt light. Here's how:
1. Connect the OBD2 scanner to the diagnostic port of your car, which is usually located under the dashboard.
2. Turn on the ignition, but don't start the engine.
3. Scroll through the menu options on the scanner and select "Reset ECU" or "Reset Maintenance Light."
4. Follow the prompts on the scanner to confirm the reset.
5. Turn off the ignition and disconnect the OBD2 scanner.
The timing belt light should now be reset.
Note: Some Toyota models require a special sequence to reset the timing belt light. Consult the owner's manual or a trusted mechanic for specific instructions for your vehicle.
