Solution

1. Preparation

Ensure the vehicle is parked in a safe location.
Connect the vehicle to a charger if the battery is low, as it may need power during the reset process.

Sit in the driver's seat and ensure the vehicle is powered on.
Tap the 'Controls' icon located at the bottom left of the touchscreen.

3. Reset the Light

Navigate to the 'Service' menu.
Select 'Software' and then choose 'Reset'.
Confirm the reset option to clear temporary faults and reset the check engine light.

4. Perform a Full Power Cycle (if necessary)

If the check engine light does not reset, perform a power cycle:
- Press and hold both scroll wheels on the steering wheel until the Tesla logo appears on the screen (this may take around 10 seconds).
- Release the scroll wheels and allow the vehicle systems to reboot.

5. Monitor the System

After the reset, monitor the vehicle for any recurring check engine light alerts.
If the light reappears, further diagnostics may be necessary to address any underlying issues.
