1. Oil Reset
If the oil service light is on, the car needs servicing. After servicing, the driving time and other data must be reset to zero, so that the service light goes off and the car's system activates a new service cycle.

2. Brake reset
1. When the brake pad is used to a certain thickness, the brake sensor wire will wear down, and the brake pad sensor wire will send a signal to the car's computer to prompt brake pad replacement. After replacing the brake pads, the brake system must be reset; otherwise, the car will continue to trigger a warning light.
2. Need to perform a reset:

one. replace the brake pad and the brake pad wear induction line;

b. brake pad warning light illuminated;

c. Repair of a short circuit in the brake pad sensor line;

d. After replacing the servomotor

3. BMS Battery Reset
For a vehicle equipped with battery management, if the battery is detected as faulty (aging or damaged), an error code will be stored in the ECU. After replacing the battery and performing a "BMS Reset," the error code can be cleared and the system can be re-paired, using relevant information from the existing battery as a standard, allowing the monitoring unit to monitor the system. This avoids false positives from instrument error messages.

4. DPF (diesel particulate filter) regeneration
Diesel particulate filter in the working process, particles accumulate in the filter, when it reaches a certain value, this will lead to a decrease in engine power and economic performance, must be removed in time to ensure that the DPF continues to function normally.

5. SAS Steering Angle Reset
Once the vehicle has been disassembled or replaced with parts related to the steering function, the steering angle learning function must be performed.

6. TPMS Tire Pressure Reset

only applicable to vehicles without tire pressure sensors.
If the tire pressure is too low or there is an air leak, replace or install tire pressure monitoring equipment, replace the tires, check for damage to the tire pressure sensor, and for cars with tire pressure monitoring functionality, check the tires during tire swapping, etc. A tire pressure reset is required after vehicle maintenance and to turn off the tire pressure warning light.

7. IMMO Key Mapping
When replacing the ignition switch key, ignition switch, instrument cluster, engine control unit (ECU), body control module (BCM) and remote control battery, IMMO key matching is required.

8. ABS Purge
In the case of replacement of the ABS system, ABS pump, brake pump, brake line and brake fluid, it is necessary to bleed the ABS system using the ABS bleeding function.

9. Sunroof Reset
The sunroof must be reset when the sunroof control unit has a communication problem or has been changed.

10. Resetting the suspension
When the body height sensor or control module in the air suspension system is replaced or the car's level is incorrect, the vehicle must perform this function to adjust the body height sensor for level calibration.

11. Resetting the gearbox (transmission)
When transmission parts wear out and aging becomes severe, the adaptive learning of the control unit does not work and the parts must be repaired and replaced, then the automatic transmission control unit must be forced to learn.

12. AFS Headlight Reset
This function can initialize the adaptive headlight system. The adaptive headlight system can automatically turn on the headlights based on ambient light intensity, monitor vehicle speed, body posture, etc., and adjust the headlight beam angle accordingly. When replacing a headlight, automatic headlight motor, or when an error code is not related to the headlight, it is necessary to perform headlight matching.

13. Injector coding
After replacing the ECU or injector, each cylinder injector must be coded to confirm or recode. This allows the cylinder to better identify each cylinder injector, ensuring precise control of fuel injection.

14.ETS Learning (accelerator matching)
Need to perform throttle matching: replace the electronic control unit, turn off the electronic control unit, replace the electronic throttle assembly, replace or remove the intake port, clean the throttle.

15. Learning about gears
Gear learning is required when replacing the engine ECU, crankshaft position sensor, crankshaft flywheel, and the error code that the gear has not learned is necessary for gear learning.

16. EGR self-learning
If the EGR fails, the vehicle's instrument panel engine/EPC fault light will illuminate, and the EGR self-learning function can turn off the fault light after cleaning or replacing the EGR valve.

17. Reset A/F
This function is used to define or learn the parameters of the air/fuel ratio.

18. Resetting AdBlue (diesel engine exhaust gas filter)
Once the exhaust gas treatment fluid (AdBlue) has been replaced or refilled, turn off the AdBlue fault light by resetting AdBlue.

19. Airbag Reset

This feature is only available for certain models; please consult the seller.
This function resets the airbag data to clear the airbag collision fault indicator.

20. Coolant flush
Use this function to activate the electronic water pump before bleeding the cooling system. Electronic water pumping systems are commonly found in BMW models.

21. Tire modification
Adjusting tire size settings after tire modification or replacement.

22. Language change
This function is used to change the system language of the vehicle's central control panel.

23. Nox Sensor Reset
The NOx sensor is used to detect the nitrogen oxide (NOx) content in the engine's exhaust gases. If the NOx fault is cleared and the NOx catalytic converter is replaced, it is necessary to reset the learned value of the catalytic converter stored in the engine's ECU.

24. Odometer reading

25. Shutdown/Startup Reset
This function is used to open or close the automatic start-stop function by setting the hidden function in the ECU (provided the vehicle has a hidden function and hardware support).

26. Seat calibration
This function is applied to match seats with a replaced and repaired memory function.

27. Mode of transport
To reduce energy consumption, the following functions can be deactivated, including limiting vehicle speed, not waking the door opening network and deactivating the remote key, etc. At this point, the transport mode must be deactivated to restore the vehicle to normal operation.

28. Windows Calibration
This feature is designed to perform door window matching in order to recover the initial ECU memory and recover the automatic up and down function of the power window.
