A car diagnostic tool also called an OBD scanner, is, as the name suggests, a car scanner that is a diagnostic scanner for your car. OBD stands for On-Board Diagnostics. The device is connected to the car via the so-called OBD port and an OBD cable (if needed).
The car diagnostic tool then accesses the data memory of the control units and the on-board electronics and evaluates or analyzes them.
For this purpose, stored data from the vehicle’s electronics is evaluated, which is essential for the detection of faults. If necessary, error codes are then generated, but these must then be analyzed using the information provided on internet databases, etc.
This is because a car code reader usually only tell you the error codes but not what it means.
The subsequent elimination of errors is possible with the help of some OBDII scan tool devices; however, this process is very complex and requires additional knowledge. Furthermore, a diagnostic device allows essential vehicle data such as fuel consumption, fluid temperatures, etc. to be readout.
