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.
