  • OIL RESET – Reset the oil service light reminder every time the oil and oil filter are changed;
  • INJECTOR – Code new injector numbers to replace the previous one when fitting the new injectors or after the replacement is completed;
  • BRAKE RESET – Deactivate and activate the brake control system, assist with brake fluid control, open and close brake pads, etc.;
  • SAS RESET – Perform steering angle sensor calibration and clear records;
  • BAT.RESET – Evaluate the battery charge state, monitor the closed-circuit current, register the battery replacement, etc.
  • BLEEDING ABS– When the ABS contains air, the ABS bleeding function must be performed to bleed the brake system to restore ABS brake sensitivity;
  • ELEC. THROTTLE RELEARN – Initialize the throttle actuators so that the “learned” values stored on ECU are returned to the default state;
  • TPMS RESET – Tyre pressure resetting is required to be performed after maintenance is performed;
  • DPF REG – Clear PM (Particulate Matter) from the DPF filter through continuous combustion oxidation mode to stabilize the filter performance;
  • GEAR LEARN – Perform gear learning for the car when the engine ECU, the crankshaft position sensor, or the crankshaft flywheel is replaced;
  • AFS RESET – Headlight matching function is used to match the headlights of the vehicle. It detects the light of the environment, then decides whether to automatically turn on the headlights, and can monitor the driving speed and body posture of the vehicle, and adjust the headlights in time.
  • EGR ADAPTION – The main purpose is to reduce nitrogen oxides (NO x ) in the exhaust gas and improve fuel economy at partial load.
  • GEARBOX ADAPTATIONS– When the gearbox is disassembled or repaired (after some car batteries are powered off), it will cause shift delay or impact problem. At this time, this function needs to be performed to automatically test the gearbox according to driving conditions. Compensate for a more comfortable and ideal shift quality.
  • SUNROOF – set the sunroof lock switch, the sunroof when it is raining, the memory function of the sliding/tilting sunroof, and the temperature threshold outside the car.
  • SUSPENSION RESET – When the body height sensor and control module in the air suspension system are replaced or the level of the car is wrong, this function needs to be performed to level the body height sensor.



This diagnostic tool LAUNCH X431 V+ 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 V+ also have the ability to actuate relays, injectors, coils, or perform system tests, etc.


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

1. After you change faulty 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.
