30 Kinds of Special Reset Service Functions Details:

Oil Reset Service

allows you to perform reset for a new calculation of Engine Oil Life system once changed the oil.

Electronic Parking Brake Reset

is important in the maintenance of electronic braking system’s safety and efficiency.

Steering Angle Calibration

helps clear the fault steering angle sensor memories and plays an important role in the steering angle sensor calibration.

ABS Bleeding

ABS brake bleeding to get a firm brake pad after air exhaustion.

TPMS (Tire Pressure Monitor System) Reset

makes sense in displaying sensor IDs from the vehicle’s ECU, inputting TPMS sensor replacement IDs and testing sensors.

Gear Learning

Leaking injectors and some dead injectors can be missed even when an injector is disabled. Otherproblems with the ignition system and mechanical components also may not show an rpm loss when aninjector is turned off

IMMO Service

it is mainly used to disable the lost vehicle keys and program a new replacement key fob.

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

allows the scan tool to evaluate the battery charge state, monitor the close-circuit current, register the battery replacement, and activate the rest state of the vehicle.

Diesel Particulate Filter (DPF) Regeneration

specially works for Diesel Particulate Filter system with DPF regeneration, DPF component replacement teach-in and DPF teach-in after replacing the engine control unit.

Electronic Throttle Position Reset

The throttle body is a tube containing a pivoting flat valve (butterfly) that is used to control the amount ofair entering an engine. In an electronically fuel injected car, a throttle position sensor and air flow sensorcommunicate with the computer, which supplies the corresponding amount of fuel needed at the injectors. It must need re-learning throttle sensor position after clearing or repair

Gearbox Matching

1. This function can complete the gearbox self-learning to improve gear shifting
2. 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.

AFS (Adaptive Front-lighting System) Reset

It detects the light of the environment, then decides whether to automatically turn on the headlights or not. It can also adjust the headlights in time by monitoring the driving speed and body posture of the vehicle.

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

Suspension Calibration

1. This function can adjust the height of the body.
2. 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.
