2025 Launch X431 V V5.0 8inch Tablet Wifi/Bluetooth Full System Diagnostic Tool

launch x431 V V7.0 8-inch Functions

1. All System Diagnostic Tool

1. Full Diagnose Function: x431 V can diagnose the electronic control system of prevailing vehicle models covering Asian, European, American and Chinese makes. Full range car models and full car systems diagnosis make it a professional automotive diagnostic tool.
2. Diagnosis functions include: Read DTCs, Clear DTCs, Read datastream, Special Function, etc.
3. Bidirectional control: Bi-Directional Control which is used to request information or command a module to perform specific tests and functions.
4. Actuation Test: It can send information to and receive information from a vehicle’s control module.
5. Key Programming: If you know the PIN# of your car, x431 V can match a new key for you.
6. ECU Coding: After replacing a new ECU for a car, X431 V can help you code it. It is very useful for mechanics.
7. Remote Assistance: launch X431 V supports remote diagnosis. If you need help from another mechanic, open the remote control function.

2. Special Functions

1) Oil Reset Service

This function can be performed in the following cases:

• 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.
• After changing engine oil or electric appliances that monitor oil life, you need to reset the service lamp.

2) Steering Angle Calibration

• To reset the steering angle, first find the relative zero point position for the car to drive in a 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.

3) Electronic Parking Brake Reset

• If the brake pad wears the brake pad sense line, the brake pad sense line sends a signal 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.
• 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 shorted and has been 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 the Anti-lock Braking System (ABS).

• When the ABS contains air, the ABS bleeding function must be performed to bleed the brake system to restore ABS brake sensitivity.
• 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 the 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:

• The ECU is replaced and the ECU does not yet store throttle working features.
• The ECU is disconnected from power and the ECU memory is lost.
• The throttle assembly is replaced.
• The intake pipe is replaced or removed, which affects idle speed control by ECU and throttle body.
• 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 the 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:

• 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.
• Battery monitoring sensor. Battery matching is performed to re-match the control module and monitoring 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:

• The exhaust back pressure sensor is replaced.
• The PM trap is removed or replaced.
• The fuel additive nozzle is removed or replaced.
• The catalytic oxidizer is removed or replaced.
• The DPF regeneration MIL is on and maintenance is performed.
• The DPF regeneration control module is replaced.
• 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 allows the crankshaft position sensor to learn the machining error of the crankshaft teeth and store it in the computer to more accurately diagnose engine misfire.

10) Immobilizer Matching

In order to prevent the car from being used by an 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.

12) Air Suspension Reset
13) Gearbox Reset
14) Sunroof Reset
15) AFS Reset
16) EGR Reset

Please note that special functions are not available for all vehicles.
