free update Konnwei KW450 Automotive Code Reader Scan tool For Audi/VW

1) Read Codes
This option is used to identify which section of the emission control system has malfunctioned.
2) Erase Codes
After reading the retrieved codes from the vehicle and certain repairs have been carried out, you can use this function to erase the codes from the vehicle. Before performing this function, please be sure thevehicle'signition key is in the ON position with the engine off.
NOTES:
A. Before performing this function, make sure to retrieve and record the trouble codes.
B. After clearing, you should retrieve trouble codes once more or turn the ignition on and retrieve codes again. If there are still some trouble codes in the system, please troubleshoot the code using a factory diagnosis guide, then clear the code and recheck.
3) Live Data
This option retrieves and displays live data and parameters from the vehicle's ECU.
4) View Freeze Frame
When an emission-related fault occurs, certain vehicle conditions are recorded by the on-board computer. This information is referred to as freeze frame data. Freeze Data is a snapshot of the operating conditions at the time of an emission-related fault.
Note: If DTCswere erased, Freeze Data may not be stored in vehicle memory depending on the vehicle.
5) I/M Readiness
I/M refers to Inspection and Maintenance that is legislated by the Government to meet federal clean-air standards. I/M Readiness indicates whether or not the various emissions-related systems on the vehicle are operating properly and are ready for Inspection and Maintenance testing.
The purpose of the I/M Readiness Monitor Status is to indicate which one of the vehicle's Monitors have run and completed their diagnosis and testing, and which ones have not yet run and completed testing and diagnosis of their designated sections of the vehicle's emissions system.
I/M Readiness Monitor Status function also can be used(after repair of a fault has been performed) to confirm that the repair has been performed correctly, and/or to check for Monitor Run Status.
6) O2 Monitor Test
The results of the O2 sensor test are not live values but instead the results of theECU's last O2 sensor test, for live O2 sensor readings.
Not all test values are applicable to all vehicles. Therefore, the list generated will vary depending on vehicle. In addition, not all the vehicles support the Oxygen Sensors screen.
7) On-Board Monitor Test
This function can be utilized to read the results of on-board diagnostic monitoring tests for specific components/systems.

8) Component Test
The Component Test function lets you initiate a leak test for the vehicle's Component system. The tool does not perform the leak test, but signals to vehicle's on-board computer are to initiate the test, Before using the system test function, refer to the vehicle's service repair manual to determine the procedures necessary to stop the test.
9) Vehicle Info
This option displays the vehicle information, such as VIN(Vehicle Identification Number),CID(Calibration ID) and CVN(Calibration Verification Number).
10 ) BAT Check
11 ) Modules Present
This option displays the vehicle communication protocol type.
12 ) DTC Lookup
This option you can enter the fault code and view the detailed description.

13 ) Review Data
This option can replay failures that store records.
14 ) Print Data
This option can upload the stored fault code to the computer.

15) OilReset
This 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.
16 ) EPBReset
