30+ Special Reset Service Functions

(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 ServiceThis 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 Resetis important in the maintenance of electronic braking system's safety and efficiency.3.Steering Angle Calibrationhelps clear the fault steering angle sensor memories and plays an important role in the steering angle sensor calibration.4.ABS BleedingThis 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 ResetThis 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 LearningThe scan tool monitors certain camshaft position sensors signals to determine if all conditions are met to continue with the procedure for Engine running7.IMMO Serviceit is mainly used to disable the lost vehicle keys and program a new replacement key fob.8.Injector CodingLeaking 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 off9.Battery Maintenance System Resetallows 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) Regenerationspecially 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 ResetThis 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) ResetThis 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 InitializationThis function can set the sunroof lock off, closed when it rains, sliding / tilting sunroof memory function, temperature threshold outside the car etc.15.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.And more....
