What Is Launch Creader V Code Scanner's Special Test III

May 14, 2011 - PRLog -- What Is Launch Creader V Code Scanner's Special Test III
In my last article, I have already introduced Launch Creader V code scanner and some of its functions, but I haven't mentioned its special tests. Today, let's see what is its special function.

In general, it has those special tests: I/M Readiness,MIL Status,O2 Sensor Test, On-board monitor test,EVAP system test,Vehicle Info. Let's talk those functions in detail.

First, 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 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 designed sections of the vehicle's emissions system. The I/M Readiness Monitor function can also 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.

Second, MIL Status.
MIL Status indicates the status of malfunction indicator lamp(MIL). The MIL on vehicle will light only when there are DTCs.

Third, O2 Sensor test.
The result of O2 sensor test are not live but instead the results of the ECU's last O2 sensor screen such as Graph Screen. Nor all test values are applicable to all vehicle. Therefore, the list generated will vary depending on vehicle. In addition, not all vehicles support the Oxygen Sensor screen. If the vehicle or a particular sensor does not support this feature, the screen list will be back.

Fourth, On-board Monitor Test.
This function can be utilized to read the results of on-board diagnostic monitoring tests for specific components/systems.

Fifth, EVAP System Test.
The EVAP test function let you initiate a leak test for the vehicle's EVAP system. The CreaderV does not perform the leak test, but signals to vehicle's on-board computer to initiate the test. Before using the system test function, refer to the vehicle's service repair manual to determinate the procedures necessary to stop the test.
Select EVAP System Test and press ENTER, the screen will display the relative information about EVAP system. Some vehicle manufacturers do not allow external devices to control vehicle system.

Sixth, Vehicle Info
Select Vehicle Info and press ENTER, the screen will display the information such as VIN(Vehicle identification Number), CID( Calibration ID ) and CVN( Calibration verify number).

With those special obd2 code scanner test, you can diagnose your car better. Don't you think so? It is really hard to find such information, so I want to share with you. If you want to know some relative auto diagnostic information, you can visit my blog autotoolsmall.wordpress.com.
