Oil Reset
The lightening of the car maintenance light indicates that the vehicle
needs maintenance. Reset the mileage or driving time to zero after the
maintenance, so the maintenance light will go out and the system will start a
new maintenance cycle.
**Throttle Adaption
**
Elec. Throttle Adaption is to utilize the car decoder to initialize the throttle actuator so that the learning value of the ECU returns to the initial state. By doing these, the movement of the throttle (or idle motor) can be more accurately controlled, thus adjust the intake volume. Situations when throttle matching is needed:
- After replacing the electronic control unit, the relevant characteristics of the throttle operation have not been stored in the electronic control unit.
- After the electric control unit is powered off, the memory of the electric control unit’s memory is lost.
- After replacing the throttle assembly, you need to match the throttle.
- After replacing or disassembling the intake port, the controlling of the idle speed by the coordination between the electronic control unit and the throttle body is affected.
- Although the characteristics of the idle throttle potentiometer have not changed, the intake volume has changed and the idle control characteristics have changed at the same throttle openings.
Steering Angle Reset
To reset the steering angle, first find the relative zero-point position for
the car to drive in straight line. Taking this position as reference, the ECU
can calculate the accurate angle for left and right steering. After replacing
the steering angle position sensor, replacing steering mechanical parts (such
as steering gearbox, steering column, end tie rod, steering knuckle),
performing four-wheel alignment, or recovering car body, you must reset the
steering angle.
Battery Matching
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:
- The 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
- 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
ABS Bleeding
When the ABS contains air, the ABS bleeding function must be performed to
bleed the brake system to restore ABS brake sensitivity. If the ABS computer,
ABS pump, brake master cylinder, brake cylinder, brake line, or brake fluid is
replaced, the ABS bleeding function must be performed to bleed the ABS.
Break-pad Reset
If the brake pad wears the brake pad sense line, the brake pad sense line
sends a signal sense line to the on-board computer to replace the brake pad.
After replacing the brake pad, you must reset the brake pad. Otherwise, the
car alarms.
Reset must be performed in the following cases:
- The brake pad is replaced or the brake pad wear sensor
- The brake pad indicator lamp is on.
- The brake pad sensor circuit is short, which is recovered.
- The servo motor is replaced.
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:
- The exhaust back pressure sensor is replaced.
- The PM trap is removed or replaced.
- The fuel additive nozzle is removed or replaced.
- The catalytic oxidizer is removed or replaced.
- The DPF regeneration MIL is on and maintenance is performed.
- The DPF regeneration control module is replaced.
Gear Learning
The crankshaft position sensor learns crankshaft gear machining tolerance and
saves to the computer to more accurately diagnose engine misfires. If gear
learning is not performed for a car equipped with Delphi engine, the MIL turns
on after the engine is started. The diagnostic device detects the DTC P1336
‘gear not learned’. In this case, you must use the diagnostic device to
perform gear learning for the car. After gear learning is successful, the MIL
turns off. After the engine ECU, crankshaft position sensor, or crankshaft
flywheel is replaced, or the DTC ‘gear not learned’ is present, gear learning
must be performed.
IMMO Service
To prevent the car being used by unauthorized keys, the anti-theft key
matching function must be performed so that the immobilizer control system on
the car identifies and authorizes remote control keys to normally use the car.
When the ignition switch key, ignition switch, combined instrument panel, ECU,
BCM, or remote-control battery is replaced, anti-theft key matching must be
performed.
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.
TPMS Reset
After the tire pressure MIL turns on and maintenance is performed, the tire
pressure resetting function must be performed to reset tire pressure and turn
off the tire pressure MIL. Tire pressure resetting must be performed after
maintenance is performed in the following cases: tire pressure is too low,
tire leaks, tire pressure monitoring device is replaced or installed, tire is
replaced, tire pressure sensor is damaged, and tire is replaced for the car
with tire pressure monitoring function.
Suspension Matching
This function can adjust the height of the body. When replacing the body
height sensor in the air suspension system, or control module or when the
vehicle level is incorrect, you need to perform this function to adjust the
body height sensor for level calibration.
AFS Reset
This feature is used to initialize the adaptive headlamp system. According to
the ambient light intensity, the adaptive headlamp system may decide whether
to automatically turn on the headlamps, and timely adjust the headlamp
lighting angle while monitoring the vehicle speed and body posture.
A/T Learning
This function can complete the gearbox self-learning to improve gear shifting
quality. When the gearbox is disassembled or repaired (after some of the car
battery is powered off), it will lead to shift delay or impact problem. In
this case, this function needs to be done so that the gearbox can
automatically compensate according to the driving conditions so as to achieve
more comfortable and better shift quality.
Sunroof Initialization
This function can set the sunroof lock off, closed when it rains, sliding /
tilting sunroof memory function, temperature threshold outside the car etc.
EGR Adaption
This function is used to learn the EGR (Exhaust Gas Recirculation) valve after
it is cleaned or replaced.
ODO Reset
- ODO reset is to copy, write, or rewrite the value of kilometers in the chip of odometer by using a car diagnostic computer and data cable, so that the odometer shows the actual mileage.
- Usually when the mileage is not correct due to the damaged vehicle speed sensor or odometer failure, it is necessary to do ODO reset after maintenance.
Airbag Reset
This function resets the airbag data to clear the airbag collision fault
indicator. When the vehicle collides and the airbag deploys, the corresponding
fault code of the collision data appears, the airbag indicator lights up, and
the fault code cannot be cleared. Since the data inside the airbag computer is
disposable, it is required that all new accessories must be replaced, but
after performing this function, the data of the airbag computer can be
recovered and the fault code can be cleared, the airbag light will go out, and
the airbag computer can continue to use.
Transport Mode
In order to reduce power consumption, the following functions may be disabled,
including limiting the vehicle speed, not waking up the door opening network,
and disabling the remote-control key, etc. At this time, the transport mode
needs to be deactivated to restore the vehicle to normal.
Stop/Start Reset
This function is used to open or close the automatic start-stop function via
setting the hidden function in ECU (provided that the vehicle has a hidden
function and supported by hardware).
NOx Sensor Reset
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.
AdBlue Reset (Diesel Engine Exhaust Gas Filter)
After the diesel exhaust treatment fluid (car urea) is replaced or filled up,
urea reset operation is required.
Seat Calibration
This function is applied to match the seats with memory function that are
replaced and repaired.
Coolant Bleeding

after repairing.
Engine Power Balance Monitoring
At the power stroke of each cylinder, power balance monitors crankshaft
acceleration, thus determining the relative power provided by each cylinder.
Gas Particulate Filter Regeneration
After long-term use of the particle catcher, fuel consumption can be
increased, engine output power can be decreased, then in this case, the GPF
needs to be replaced or regenerated.
Motor Angle Calibration
There is a deviation between the rotor position detected by the angle position
sensor of the motor and the actual rotor magnetic fifi eld position, so it is
necessary to calibrate the motor angle.
High Voltage Battery Diagnostics
