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 as 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.
