Solution

1. Preparation

Gather necessary tools: OBD-II scanner and a vehicle owner's manual.
Ensure the vehicle is parked on a level surface, and the engine is turned off.

2. Verify Fluid Condition

Start the engine and let it reach normal operating temperature.
Shift through all gears and return to park.
Check the transmission fluid level using the dipstick (if equipped) and inspect fluid quality.
If fluid is low or dirty, replace it before proceeding with the reset.

3. Reset the Transmission Fluid Light

Turn the ignition key to the "ON" position without starting the engine.
Use the OBD-II scanner to access the vehicle's diagnostic system.
Navigate to the transmission control module (TCM) and follow the prompts to reset the fluid light. This process may vary by scanner; refer to the scanner's manual if necessary.
After the reset, turn off the ignition and then restart the engine to ensure the light is no longer illuminated.

4. Final Check

Drive the vehicle for a short distance to confirm that the transmission fluid light does not reappear.
Monitor the dashboard for any other warning lights.
