2.2.7.9 Data Flow Table

By reading the Data Flow Table on the fault diagnosis tester, you can inspect switches, sensors,
actuators working state without dismantling any components. Before the control system diagnosis,
observing and analyzing data is the first step, 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 whether the current vehicle diagnostic data is normal or not.

1. Run the engine to reach normal working temperature.

2. Rotated ignition switch is OFFposition。

3. Connect the fault diagnosis tester.

4. Rotated ignition switch in the ON position.

5. Select Engine/Read data stream.

6. Refer to the following table and inspect the data of each item.

1. First step: At cold engine, turn the key switch to ON position, inhibit the engine (for about

30s)
