5.7. INJECTOR CODING
This function can write the identification code of the fuel injector into the ECU so that the ECU can recognize
and work normally. Write actual injector code or rewrite code in the ECU to the injector code of the
corresponding cylinder for controlling accurately and correcting cylinder injection quantity.
After the ECU or injector is replaced, the injector code of each cylinder must be confirmed or re-coded so that
the cylinder can better identify injectors to accurately control fuel injection.
In general cases, there is no need to do the coding matching function after cleaning.
The identification of the fuel injector includes its working accuracy value and type value. When
replacing it, you need to find the corresponding model for replacement.
At present, mainstream cars support injector coding functions.
The operation guidelines of the Injector Coding function are shown below:
1. Enter the Injector coding menu and choose relevant chassis models according to the vehicle being
tested.
2. Enter the Fuel injection nozzle injection volume adjustment menu.
Read the note displayed carefully and press OK after the reading.
