Injector Coding; Battery Maintenance System Reset; Diesel Particulate Filter (Dpf) Regeneration - Launch X-431 Manual

LAUNCH
BCM, or remote control battery is replaced, anti-theft key matching must be
performed.

6.8 Injector Coding

Write injector actual code or rewrite code in the ECU to the injector code of the
corresponding cylinder so as to more accurately control or correct cylinder
injection quantity.
After the ECU or injector is replaced, injector code of each cylinder must be
confirmed or re-coded so that the cylinder can better identify injectors to
accurately control fuel injection.

6.9 Battery Maintenance System Reset

This function enables you to perform a resetting operation on the monitoring unit
of vehicle battery, in which the original low battery fault information will be
cleared and battery matching will be done.
Battery matching must be performed in the following cases:
a) Main battery is replaced. Battery matching must be performed to clear
original low battery information and prevent the related control module from
detecting false information. If the related control module detects false
information, it will invalidate some electric auxiliary functions, such as
automatic start & stop function, sunroof without one-key trigger function,
power window without automatic function.
b) Battery monitoring sensor. Battery matching is performed to re-match the
control module and motoring sensor to detect battery power usage more
accurately, which can avoid an error message displaying on the instrument
panel.

6.10 Diesel Particulate Filter (DPF) Regeneration

DPF regeneration is used to clear PM (Particulate Matter) from the DPF filter
through continuous combustion oxidation mode (such as high temperature
heating combustion, fuel additive or catalyst reduce PM ignition combustion) to
stabilize the filter performance.
DPF regeneration may be performed in the following cases:
a) The exhaust back pressure sensor is replaced.
b) The PM trap is removed or replaced.
c) The fuel additive nozzle is removed or replaced.
