- Perform Actuator Tests: These tests help verify the functionality of various components like solenoids, relays, and motors, ensuring they respond correctly to commands from the car’s computer.
- Conduct System Resets: After repairs, a diagnostic tester enables you to reset the car’s computer and clear DTCs, ensuring smooth operation.
