Oil Reset Service
This function allows you to perform reset for the engine oil life system,
which calculates an optimal oil life change interval depending on the
vehicle driving conditions and climate.
This function can be performed in the following cases:
1. If the service lamp is on, you must provide service for the car. After
service, you need to reset the driving mileage or driving time so that the
service lamp turns off and the system enables the new service cycle.
2. After changing engine oil or electric appliances that monitor oil life, you
need to reset the service lamp.
Electronic Parking Brake Reset
1. 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.
2. Reset must be performed in the following cases:
a) The brake pad and brake pad wear sensor are replaced.
b) The brake pad indicator lamp is on.
c) The brake pad sensor circuit is short, which is recovered.
d) The servo motor is replaced.

Steering Angle Calibration
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.
ABS Bleeding
This function allows you to perform various bi-directional tests to check the
operating conditions of Anti-lock Braking System (ABS).
1. When the ABS contains air, the ABS bleeding function must be
performed to bleed the brake system to restore ABS brake sensitivity.
2. 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.
Tire Pressure Monitor System Reset
This function allows you to quickly look up the tire sensor IDs from the
vehicle’s ECU, as well as to perform TPMS replacement and sensor test.
1. 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.
2. 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.
Gear Learning
The crankshaft position sensor learns crankshaft tooth machining tolerance
and saves to the computer to more accurately diagnose engine misfires.
If tooth 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 'tooth not learned'. In this case, you must use the diagnostic
device to perform tooth learning for the car.
After tooth learning is successful, the MIL turns off. After the engine ECU,
crankshaft position sensor, or crankshaft flywheel is replaced, or the DTC
'tooth not learned' is present, tooth learning must be performed.

IMMO Service
An immobilizer is an anti-theft mechanism that prevents a vehicle’s engine
from starting unless the correct ignition key or other device is present.
Most new vehicles have an immobilizer as standard equipment. An
important advantage of this system is that it doesn’t require the car owner
to activate it since it operates automatically.
An immobilizer is considered as providing much more effective anti-theft
protection than an audible alarm alone. As an anti-theft device, an
immobilizer disables one of the systems needed to start a car’s engine,
usually the ignition or the fuel supply.
This is accomplished by radio frequency identification between a
transponder in the ignition key and a device called a radio frequency reader
in the steering column. When the key is placed in the ignition, the
transponder sends a signal with a unique identification code to the reader,
which relays it to a receiver in the vehicle’s computer control module.
If the code is correct, the computer allows the fuel supply and ignition
systems to operate and start the car. If the code is incorrect or absent, the
computer disables the system, and the car will be unable to start until the
correct key is placed in the ignition.
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.
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:
-- Page
22
--
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.
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.
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.
