5.10 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.
d) The catalytic oxidizer is removed or replaced.
e) The DPF regeneration MIL is on and maintenance is performed.
f) The DPF regeneration control module is replaced.

6.11 Electronic Throttle Position Reset

This function enables you to make initial settings to throttle actuators and returns
the "learned" values stored on ECU to the default state. Doing so can accurately
control the actions of regulating throttle (or idle engine) to adjust the amount of
air intake.
