2.12.7.10 Action Test Table
By reading the "Action Test Table" on the scan tool, you can check switches, sensors, actuators working state without removing any
parts. Before the control system diagnosis, carrying out action test is a prerequisite, so that the diagnose time could be shortened.
Note
Data under normal conditions is listed in the following table for reference only. Do not determine whether a part is faulty
solely based on these reference values. Under normal circumstances you can compare the vehicle that needs to be
repaired with a normal working vehicle in the same state to determine the current vehicle diagnostic data is normal or
not.
1. Run the engine to reach normal working temperature.
2. Turn the ignition switch to "OFF" position.
3. Connect scan tool.
4. Turn the ignition switch to "ON" position.
5. Select "engine" / "Action Test".
6. Refer to the following table to test.
