7. Troubleshooting
7.1 Fault Code Analysis
Understanding fault codes is crucial for effective troubleshooting. Fault codes are structured to provide information about the system and type of fault.

- No.1 (First Character): Indicates the system (P-Powertrain, C-Chassis, B-Body, U-Network Communication).
- No.2 (Second Character): Indicates the type of fault (0-Universal, 1-Manufacturer Defined, 2-Universal, 3-P3000-P3399: Customized by manufacturer, P3400-P3FFF: Common fault code).
- No.3 (Third Character): Indicates the specific system component (e.g., 1-Fuel/Air Metering, 2-Fuel/Air Metering (Injector Circuit), 3-Ignition System, 4-Emission Control, 5-Speed and Idle Control, 6-Computer or Auxiliary Output Circuit, 7-Transmission, 8-Transmission, 9-Gearbox, A/B/C-Hybrid Power System).
- No.4, 5 (Fourth and Fifth Characters): Provide specific fault details.
7.2 Common Issues
- Scanner does not power on: Ensure the 16-pin connector is securely plugged into the vehicle's OBD-II port and the vehicle's ignition is on (or engine running). Check the vehicle's fuse for the OBD-II port if necessary.
- Connection fails (orange indicator): Verify the connection to the OBD-II port. Ensure the vehicle is OBD-II compliant and the year of manufacture is within the supported range.
- Cannot clear fault codes: Some persistent faults may require multiple drive cycles or addressing the underlying mechanical issue before the code can be permanently cleared.
