Some ECUs can be read and written directly via the OBD diagnostic socket.
In this case, it is therefore not necessary to remove the computer from the vehicle.
The OBD cable must be connected on one side to the vehicle's diagnostic socket and on the other side to the "OBD" connector of the Autotuner tool.
The help interface is used to locate the diagnostic socket.
It is important to check the battery voltage. If it is less than 12V, it is required to connect a charger to the battery during the whole process.
When a charger is required, Autotuner software will inform the user before reading. Some cars must also be in a specific mode in order to start the reading process. The help interface will guide you as to what to do.
