Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.
Allow the engine to cool if it has been recently running.

2. Inspect and Clear Codes

Use the OBD-II scanner to read and record any error codes.
If codes are present, research them to understand the underlying issues.
Clear the error codes and reset the check engine light.

3. Check Connections and Components

Inspect all connectors and wiring harnesses related to the engine control unit (ECU) to ensure they are secure.
Reconnect any loose connections found during inspection.
If any components were serviced (like spark plugs or sensors), ensure they are correctly installed.

4. Perform Functional Tests

Reconnect the battery and start the engine.
Monitor the engine for unusual noises or behaviors.
Test the vehicle under various conditions (idle, acceleration) to ensure proper operation.

5. Finalize and Document

If the check engine light remains off and the vehicle operates normally, document the findings and repairs made.
If the light reappears, consult the error codes again for further diagnosis.
