Injector Coding; Urea Drive (Def); Flash Data Conversion; Data Optimization - Launch PRO3S+ Manual

LAUNCH
status of the engine.
It needs to be performed in the following cases:
• When engine is running abnormally or certain cylinder does not work.

6.4 Injector coding

This function can write injector actual code or rewrite code in the ECU to the
injector code of the corresponding cylinder, so as to control or correct the
cylinder injection quantity accurately.
It needs to be performed in the following cases:
• After the ECU or injector is replaced.

6.5 Urea drive (DEF)

This function can drive the urea pump to perform reverse pumping, compression,
injection and other operations through the diagnostic scanner.
It needs to be performed in the following cases:
• After the urea pump maintenance is performed.

6.6 Flash data conversion

This function enables you to convert the backup data into standard format data
such as .hex, .s19 and .bin etc.
It needs to be performed in the following cases:
• Need the standard format data to perform other operations.

6.7 Data optimization

This function enables you to optimize the vehicle power by revising vehicle data.

6.8 Nox sensor

NOx sensor is a sensor used to detect the content of nitrogen oxides (NOx) in
engine exhaust. If the NOx fault is re-initialized and the NOx catalytic converter
is replaced, it is necessary to reset the catalytic converter learned value stored
in the engine ECU.
