Full Bi-Directional Control ( ACTVE TEST) of LAUNCH X431 PRO3S+

This diagnostic tool LAUNCH X431 X431 PRO3S+ supports active test (Bi-directional control) to request information or command a module to perform specific tests and functions. For instance, in the case of OBD II generic information Mode 1, you can initiate a request for information from the powertrain control module, and the PCM responds by sending the information back to the scan tool for display. This LAUNCH X431 PAD V also have the ability to actuate relays, injectors, coils, or perform system tests, etc.

ECU CODING Function of LAUNCH X431 X431 PRO3S+

Because every automobile actuator has a record code in ECU, which is the basis for automobile computer to mobilize their work. LAUNCH X431 PRO3S+ is equipped with advanced ECU coding function for addressing the following issues:

1. After you change the bad actuators or certain parts, you need to use this function to make a new code and recognize the new actuators.

2. By changing the code with the ECU coding, it’s easy to improve vehicle performance or stimulate high-end functions for the car.

3. ECU coding enables multiple car systems to recognize each other and then the actuators can start to work.

Accurate ADAS Calibration functions

Advanced Driver Assistance System (ADAS) is an electronic component in a vehicle, including various safety functions of the vehicle, such as automatic emergency braking (AEB), lane departure warning (LDW),lane keeping assist, blind spot elimination, night vision camera and Adaptive lighting. (NOTE: Need to be purchased separately)

TPMS Diagnostic function

LAUNCH X431 PROS3+ can work with wireless tire pressure diagnostic tool (optional accessory) toachieve the features of TPMS activation, programming and learning.

a)Activation:to activate the sensor’s IlD, wheel pressure, sensor frequency, tire temperature and battery status.

b)Programming:to program sensor data to a blank Thinkcar sensor, so as to replace a sensor that is in low battery and does not function properly. There are three sensor programming methods available:automatic, manual, and via activation replication.

c) Learning:to write the sensor ID into the vehicle ECU for sensor identification.

All in 1 graphic data stream

view and capture (record) real-time Live Data. This data including current operating status for parameters and /or sensor information can provide insight on overall vehicle performance. It can also be used to guide vehicle repair.

30+ Special Reset Service Functions

LAUNCH X431 PRO3S+ scan tool gives you the ability to use dealership level relearn procedures to complete repairs/maintenance: Oil Reset, ABS Bleeding, Injector coding, Gear Reset, SAS Reset, TPMS Reset, DPF Reset, BMS Reset, ETS Reset, AFS Reset, EGR Adaptation, GEARBOX, SUNROOF, SEAT Calibration, etc.

(NOTE:You can find 15 kinds of commonly used reset functions in the reset menu, and other special functions in the car brand diagnostic softwares menu)

1.Oil Lamp,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.

2.Electronic Parking Brake Reset

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

3.Steering Angle Calibration

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

4.ABS Bleeding

This function allows you to perform various bi-directional tests to check the operating conditions of Anti-lock Braking System (ABS).

5.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.

6.Gear Learning

The scan tool monitors certain camshaft position sensors signals to determine if all conditions are met to continue with the procedure for Engine running

7.IMMO Service

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

8.Injector Coding

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

9.Battery Maintenance System Reset

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.

10.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.

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.

12.Gearbox Matching

(1). This function can complete the gearbox self-learning to improve gear shifting quality.

(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.

13. AFS (Adaptive Front-lighting System) 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.

14. 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.
