1.ABS Bleed: This is a procedure to remove air bubbles from the brake system's Antilock Braking System (ABS) unit. It ensures proper brake performance.2.Battery: In automobiles, the battery is typically used to store and provide electrical energy to start the engine and power the vehicle's electronic systems.
3.DPF ( Particulate Filter): This is a device used to reduce the emissions of particulate matter from the exhaust of a engine. It collects and stores particulate matter, and then removes it through a regeneration process under specific conditions.
4.EPB (Electronic Parking Brake): Unlike the traditional mechanical handbrake, the electronic parking brake is a braking system controlled by electronic systems. It is typically operated through buttons or switches.

5.lmmokey : This is an -theft system that prevents a vehicle from being started unless the correct key or fob is present.

6. Oil Reset: This refers to the process of resetting the engine oil change timer or reminder system in a vehicle after changing the engine oil. This is done through specific steps to accurately record the next oil change.
7.SAS : This is a sensor that monitors the angle at which the driver turns the steering wheel,allowing the vehicle's stability control system to make corresponding adjustments based on the steering wheel's position.
8.TPMS : This is a system used to monitor the air pressure in a vehicle's tires. If the pressure in any of the tires falls below a safe level, the system will issue a warning.
9.TPS: It is a sensor that monitors the position of the throttle in the engine. It provides information about the engine's load so that the fuel supply can be controlled accordingly.
10.Gear Learn: This refers to the modern automatic transmission system's ability to adjust its operation based on the driver's driving habits and conditions, providing a better driving experience and fuel efficiency.
11.CVT (Continuously Variable Transmission): This is an automatic transmission that, unlike traditional fixed-gear transmissions, can smoothly provide a continuously variable range of gear ratios for optimal power transfer.

12.Suspension: This refers to the system of springs, shock absorbers, and linkages that connect a vehicle to its wheels.

13.Seat Reset: This could refer to resetting the position or settings of power-adjustable seats.
14.O-dometer Adjustment: This is typically done for maintenance or repair purposes to ensure the odometer displays the correct mileage.15.VIN Modification：Update or change the vehicle identification number.

16. PRV valve (Pressure Relief Valve) is a critical component for controlling and maintaining pressure in a
hydraulic system. Testing the PRV valve may involve checking its functionality to ensure it operates correctly.

17.Idle Speed Adjustment: refers to the process of setting the engine's idle speed, which is the rotational speed of the engine when the vehicle is stationary and the engine is not under load.

18.ECU Setting: This can refer to configuring or adjusting the settings of the Engine Control Unit.
19.Clear spec DTC (Diagnostic Trouble Codes): This involves erasing or clearing specific fault codes stored in the vehicle's computer.
20.Broken Cylinder Test: This could refer to a diagnostic test to check if a cylinder in the engine is functioning properly.

21.Clutch Matching：refers to the process of ensuring that a newly installed clutch is properly aligned and synchronized with the other components of the transmission system, such as the pressure plate and release bearing.
