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 theon-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 continuouscombustion 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 beperformed so that the immobilizer control system on the car identifies and authorizes remote control keysto 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 soas 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 identifyinjectors to accurately control fuel injection.

11. TPMS Reset
After the tire pressure MIL turns on and maintenance is performed, the tire pressure resetting functionmust be performed to reset tire pressure and turn off the tire pressure MIL.Tire pressure resetting mustbe performed after maintenance is performed in the following cases: tire pressure is too low, tire leaks, tirepressure 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 airsuspension system, or control module or when the vehicle level is incorrect, you need to perform thisfunction 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, theadaptive 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 isdisassembled or repaired (after some of the car battery is powered off), it will lead to shift delay or impactproblem. In this case, this function needs to be done so that the gearbox can automatically compensateaccording 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 theairbag 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 thevehicle speed, not waking up the door opening network, and disabling the remote control key, etc. At thistime, the transport mode needs to be deactivated to restore the vehicle to normal.

20. A/F Reset
