What Is Computerized Diagnostics?

Faults occurring in older-model vehicles were usually mechanical; as today's technology advanced, vehicles evolved too, and the electronic control unit system began to be used in vehicle systems.

The electronic control unit is commonly referred to as the ECU.

All vehicles produced after 1999 have an electronic control unit.

Thanks to the electronic control unit, errors coming from the modules on the vehicle are displayed on the vehicle's instrument cluster.

Vehicles with an electronic control unit have an OBD (on board diagnostic) socket.

The OBD socket enables us to communicate with the modules inside the vehicle. We can communicate with modules such as the engine, airbag and ABS.

How Is Diagnostics Performed?

• The priority is always to use the right diagnostic tool for the right vehicle.
• The diagnostic tool's communication cable must be connected to the vehicle's OBD socket.
• To perform diagnostics inside the vehicle, the vehicle's ignition must be switched on.
• If the connections are made correctly, the device and the vehicle's electronic control unit can communicate.
• Through the program installed on the computer, we can run a full system scan in the vehicle or scan a system module of our own choosing.
• If it finds a system issue or error, it reports the fault as a fault code, with a description next to the fault code.
• After diagnostics is performed, if there is an error, it can be erased via the ECU. If it is a communication error or a temporary fault, the diagnostic tool erases the error via the ECU.
• When the system or module scan is run again and no error is shown, the operation has been completed successfully. If it shows the same error, it is a permanent fault that needs to be repaired; after the repair, it is erased again.
• If, in the case of a permanent fault, a part or sensor on the vehicle is being replaced, an adaptation may be required.

NOTE: Not every diagnostic tool can perform coding, adaptation and programming operations.

As today's technology advances, the automotive industry continues to develop. In-vehicle computerized diagnostic tools have now become more practical, more robust, self-updating professional devices.
