Solution

1. Preparation

Gather necessary tools: OBD-II scanner, Tesla mobile app.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Confirm that the vehicle's battery is charged.

2. Connect OBD-II Scanner

Plug the OBD-II scanner into the vehicle’s diagnostic port, typically located under the steering column.
Turn on the vehicle without starting the engine (press the brake pedal and push the start button).

3. Read and Clear Codes

Follow the instructions on the OBD-II scanner to read any stored trouble codes.
If any codes are present, take note of them and address any additional issues if necessary.
Use the scanner to clear the codes, which should also turn off the check engine light.

4. Reset via Tesla Touchscreen

On the Tesla touchscreen, navigate to the "Service" menu.
Select "Reset" or "Power Off" to reset the vehicle’s systems.
Wait for at least 2 minutes, then turn the vehicle back on to check if the light has cleared.

5. Test Drive

Drive the vehicle for a short distance (approximately 10-15 minutes) to ensure the check engine light does not reappear.
Monitor the vehicle for any abnormal behavior during the drive.
