Hint:
Performing an active test enables components including the relays, vsv (vacuum switching valve) and actuators, to be operated without removing any parts.
The active test can be performed with the intelligent tester. Performing the active test as the first step of troubleshooting is one method of shortening diagnostic time.
Data list can be displayed during active test.
Hint:
*: When cranking the engine, each cylinder measures the engine rpm.
In this active test, the fuel and ignition of all cylinders is cut, and cranking occurs for approximately 10 seconds. Then, each cylinder measures the engine rpm. If a cylinder's engine rpm is higher than the others, that cylinder's compression pressure is compared to the others, and whether or not the compression pressure is low can be determined.
Hint:
If the results are not displayed normally, select the display items from the data list before performing the active test. Select the following menu items: diagnosis / enhanced obd ii / data list / user data / eng speed #1 and eng speed #2, eng speed #3, eng speed #4 (press the yes button to change the eng speed #1 to #4 is yes) and then press the enter button.
Hint:
After performing the above procedure, the active test's compress check will start. Fuel injection for all cylinders is prohibited, and the each cylinder's engine rpm measurement will enter standby.
Hint:
At first, the tester's display will show each cylinder's engine rpm measurement to be extremely high. After approximately 10 seconds of engine cranking, each cylinder's engine rpm measurement will change to the actual engine rpm.

Prolonged and repeated contact with engine oil will
cause the loss of natural oils from the skin, leading to
