Solution

1. Preparation

Gather tools and materials required for diagnostics and repairs.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to ensure safety.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition key to the "ON" position without starting the engine.
Read the codes and write them down for reference.
Compare codes against a repair manual or online database to identify issues.

3. Inspect and Address Issues

For codes related to maintenance items (e.g., oil change, tire pressure), perform the necessary service.
If codes indicate a fault in a specific system (e.g., emissions, transmission), proceed with targeted inspections:
- Emissions Codes: Inspect the catalytic converter and oxygen sensors.
- Transmission Codes: Check transmission fluid levels and inspect for leaks.
- Engine Codes: Inspect ignition system components like spark plugs and coils.

4. Reset the Warning Light

Once repairs are completed, reconnect the negative battery terminal.
Use the OBD-II scanner to clear the diagnostic trouble codes.
Turn the vehicle on and observe the dashboard for warning light status.
