1. Oil Reset
The lightening of the car maintenance light indicates that the vehicle needs maintenance.
After maintenance, reset the mileage or travel time to zero, the maintenance light goes out, and the system starts a new maintenance cycle.
2. Electric Throttle Adaption
Electric Throttle Adaption is to utilize the car decoder to initialize the throttle actuator, so that the learning value of the ECU returns to the initial state. By doing so, the movement of the throttle (or idle motor) can be more accurately controlled, thus adjust the intake volume.
3. Steering Angle Reset
To reset the steering angle, first find the relative zero point position ofthe car to drive in 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.
4. Battery Matching
This function enables you to perform a resetting operation on the monitoring unit of vehicle battery, in which the original low battery, fault information will be cleared and battery matching will be done.
5. ABS Bleeding
When the ABS contains air, the ABS bleeding function must be performed to bleed the brake system torestore ABS brake sensitivity. lf the ABS computer, ABS pump, brake master cylinder, brake cylinder, brakeline, or brake fluid is replaced, the ABS bleeding function must be performed to bleed the ABS.
6. Break-pad Reset
lf the brake pad wears the brake pad sense line, the brake pad sense line sends a signal sense line 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.
7. 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.
8. Gear Learning
The crankshaft position sensor learns crankshaft gear machining tolerance and saves to the computerto more accurately diagnose engine misfires. lf gear learning is not performed for a car equipped withDelphi engine, the MlL turns on after the engine is started.The diagnostic device detects the DTC P1336’gear not learned’. In this case, you must use the diagnostic device to perform gear learning for the car.After gear learning is successful, the MIL turns off. After the engine ECU, crankshaft position sensor, orcrankshaft flywheel is replaced, or the DTC ‘gear not learned” is present, gear learning must be performed.
9. IMMO Service
To prevent the car being used by unauthorized keys, the anti-theft key matching function must be performed, so that the immobilizer control system on the car identifies and authorizes remote control keys to normally use the car. When the ignition switch key, ignition switch, combined instrument panel, ECU, BCM, or remote control battery is replaced, anti-theft key matching must be performed.
10. Injector Coding
Write injector actual code or rewrite code in the ECU to the injector code of the corresponding cylinder so as to more accurately control or correct cylinder injection quantity. After the ECU or injector is replaced, injector code of each cylinder must be confirmed or re-coded so that the cylinder can better identify injectors to accurately control fuel injection.
11. TPMS Reset
After the tire pressure MIL turns on and maintenance is performed, the tire pressure resetting function must be performed to reset tire pressure and turn off the tire pressure MIL. Tire pressure resetting must be performed after maintenance is performed in the following cases: tire pressure is too low, tire leaks, tire pressure monitoring device is replaced or installed, tire is replaced, tire pressure sensor is damaged, and tire is replaced for the car with tire pressure monitoring function.
12. Suspension Matching
This function can adjust the height of the body. 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.
13. AFS 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 adjustthe headlamp lighting angle while monitoring the vehicle speed and body posture.
14. A/T Learning
This function can complete the gearbox self-learning to improve gear shifting quality. 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.
15. 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.
16 EGR Adaption
This function is used to learn the EGR (Exhaust Gas Recirculation) valve after it is cleaned or replaced.
17. ODO Reset
a) ODO reset is to copy, write, or rewrite the value of kilometers in the chip of odometer by using a car diagnostic computer and data cable, so that the odometer shows the actual mileage.
b) Usually when the mileage is not correct due to the damaged vehicle speed sensor or odometer failure, it is necessary to do ODo reset after maintenance.
18. Airbag Reset
This function resets the airbag data to clear the airbag collision fault indicator. When the vehicle collidesand the airbag deploys, the corresponding fault code of the collision data appears, the airbag indicator lights up, and the fault code cannot be cleared. Since the data inside the airbag computer is disposable, it is required that all new accessories must be replaced, but after performing this function, the data of the airbag computer can be recovered and the fault code can be cleared, the airbag light will go out, and theairbag computer can continue to use.
19. Transport Mode
ln order to reduce power consumption, the following functions may be disabled, including limiting the vehicle speed, not waking up the door opening network, and disabling the remote control key, etc. At this time, the transport mode needs to be deactivated to restore the vehicle to normal.
20. A/F Reset
This function is applied to set or learn Air/Fuel ratio parameters.
21. Stop/Start Reset
This function is used to open or close the automatic start-stop function via setting the hidden function in ECU (provided that the vehicle has a hidden function and supported by hardware).
22. NOx Sensor Reset
NOx sensor is a sensor used to detect the content of nitrogen oxides (NOx) in engine exhaust. lf the NOx fault is re-initialized and the NOx catalytic converter is replaced, it is necessary to reset the catalytic converter learned value stored in the engine ECU.
23. AdBlue Reset (Diesel Engine Exhaust Gas Filter)
After the diesel exhaust treatment fluid (car urea) is replaced or flled up, urea reset operation is required.
24. Seat Calibration
This function is applied to match the seats with memory function that are replaced and repaired.
25. Coolant Bleeding
Use this function to activate the electronic water pump before venting the cooling system.
26. Tyre Reset
This function is used to set the size parameters of the modified or replaced tire.
27. Windows Calibration
This feature is designed to perform door window matching to recover ECU initial memory, and recover the automatic ascending and descending function of power window.
28. Language Change
This function is used to change the system language of the vehicle central control panel.
