3.5.7.7 Data glow 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 OFF position。

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)
