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. 
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.
