2. Special Functions: 

1) Oil Reset Service
This function can be performed in the following cases:
a). 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.
b). After changing engine oil or electric appliances that monitor oil life, you need to reset the service lamp.’

2) Steering Angle Calibration
a). 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.
b). 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.

3) Electronic Parking Brake Reset
a). If the brake pad wears the brake pad sense line, the brake pad sense linesends 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.
b). Reset must be performed in the following cases:
The brake pad and brake pad wear sensor are replaced.
The brake pad indicator lamp is on.
The brake pad sensor circuit is short, which is recovered.
The servo motor is replaced.

4) ABS Bleeding
This function allows you to perform various bi-directional tests to check the operating conditions of Anti-lock Braking System (ABS).
a). When the ABS contains air, the ABS bleeding function must be performed to bleed the brake system to restore ABS brake sensitivity.
b). 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.

5) Electronic Throttle Position Reset/Learn
This function enables you to initialize the throttle actuators so that the “learned” values stored on ECU are returned to the default state. Doing so can accurately regulate throttle
(or idle engine) operations to control the amount of air intake. Throttle matching must be performed in the following cases:

a) The ECU is replaced and the ECU does not yet store throttle working features.
b)The ECU is disconnected from power and the ECU memory is lost.
c) The throttle assembly is replaced.
d) The intake pipe is replaced or removed, which affects idle speed control by ECU and throttle body.
e) The throttle is cleaned. Although the idle throttle potentiometer features remain unchanged, with the same throttle opening, the air inflow has changed and idle speed control features have changed.

6)  Battery Register/Battery Maintenance
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.

7)  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 rep
g) Tire Pressure Monitor System Reset

8) Tire Pressure Monitor System Reset:
This function is used to reset the tire pressure sensor. When the car tire air pressure fault indicator is on, after the repair, the tire pressure system needs to be reset by the tire pressure reset function, and the tire pressure fault indicator is extinguished.

9) Gear Learning:
The crankshaft position sensor adaptive learning, the crankshaft position sensor learns the machining error of the crankshaft teeth, and stores it in the computer to more accurately diagnose the engine misfire.

10) Immobilizer Matching:
In order to prevent the car from being used by the illegal key, the car can be opened and used after the anti-theft control system on the car recognizes and authorizes the remote control key through the anti-theft key matching function.

11) Fuel Injector Coding:
This function can write the actual code of the injector or rewrite the code stored in the ECU into the code corresponding to each cylinder nozzle, so as to more accurately control or correct the fuel injection amount of each cylinder.

How to connect Launch X431 V8 to Vehicle:

The method used to connect the diagnostic connector to a vehicle’s DLC depends on the vehicle’s configuration as follows:
1)A vehicle equipped with an OBD II management system supplies both communication and 12V power through a standardized DLC.
2)A vehicle not equipped with an OBD II management system supplies communication through a DLC connection, and in some cases supplies 12V power through the cigarette lighter receptacle or a connection to the vehicle battery.

Follow the steps mentioned below to connect OBD II vehicle:
1. Locate vehicle’s DLC socket.
2. Plug the diagnostic connector into the vehicle’s DLC socket (It is suggested to use the OBD II extension cable to connect the diagnostic connector and DLC socket.).

3. Choose one of the two ways to obtain power from:
a) Power adaptor: Connect one end of the included power adaptor to DC IN  port of X-431 V tablet, and the other end to AC outlet.
b) Internal battery pack

For non-OBDII vehicle, proceed as follows:

1. Locate vehicle’s DLC socket.
2. Select the corresponding non-16pin connector.
3. Plug the non-16pin end of the connector into the DLC socket, then connect the other end to the OBD I adaptor, and then tighten the captive screws.
4. Connect the other end of the adaptor to the included diagnostic connector.
5. To supply power to OBD I adaptor from:
a) Cigarette Lighter: Connect one end of the cigarette lighter cable to vehicle’s cigarette lighter receptacle, and the other end to the power jack of OBD I adaptor.

b) Battery Clamps Cable: Connect one end of the battery clamps cable to vehicle’s battery, and the other end to the power jack of OBD I adaptor.
