A car diagnostic tool interacts with a vehicle's on-board computer system to gather diagnostic information about the vehicle's health and performance. These tools can read fault codes, monitor sensor data, and conduct various tests to identify issues with the engine, transmission, emissions system, and other components, enabling the technician to diagnose and repair the problem.
Code Readers: These are basic diagnostic tools that can only read and clear diagnostic trouble codes. They are typically more affordable than full-function OBD2 scanners and do not provide advanced diagnostic capabilities.
OBD2 Scanners: These handheld devices plug into the OBD2 port of a vehicle (usually located under the dashboard) to read diagnostic trouble codes (DTCs), view real-time data from sensors, and perform basic diagnostic functions.
Multimeters: Multimeter tools measure voltage, resistance, and other electrical parameters in a vehicle's electrical system. They are used to diagnose issues related to electrical components such as sensors, switches, and wiring.
