Ensure the vehicle is parked on a level surface and the engine is off.

2. Confirm Fluid Level

Open the hood and locate the transmission dipstick (if applicable).

If low, add the appropriate type of transmission fluid as specified in the owner's manual.

Connect the OBD-II scanner to the vehicle's diagnostic port, usually located under the dashboard near the steering column.
Turn the ignition to the "On" position without starting the engine.
Navigate to the “Transmission” section on the scanner and select “Clear Codes” or “Reset Transmission Light.”
Follow the prompts on the scanner to complete the reset process.

4. Power Cycle the Vehicle

Disconnect the OBD-II scanner.
Turn off the ignition and wait for at least 5 seconds.
Start the engine to ensure the transmission fluid light is off.
