2.2.7.9 Data Stream List
By reading the "Data Stream List" on the scan tool, you can check switches, sensors, actuators working state without removing any
parts. 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 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 the scan tool.
4. Turn the ignition switch to "ON" position.
5. Select "Engine"/"Read data stream".
6. Refer to the table and check all the data.

ECM monitors the current charging system
working conditions.
Engine Speed

The scan tool shows the current actual engine
speed calculated by ECM through the crankshaft
position sensor input.
Target Idle Speed (No
Compensation)
800 rpm
800 rpm
1,500 rpm
The scan tool shows the target idle speed set by
ECM and the current actual idle speed, said ECM
instructions. ECM-based engine coolant
temperature sensors signal and compensation
signals for various engine loads in order to
maintain desired engine idle speed.

The scan tool shows -40°C (-40 ºF) to 130°C
(266 ºF). After heating, sensor (internal
resistance decreases) voltage signal reduces.
ECM will interpret the reduced voltage signal as
engine warmed up. This signal is one of the
conditions used to determine whether to activate
the closed-loop fuel system control, and also an
important injection timing reference signal.

Sensor voltage is the value actually received by
ECM. The intake air temperature is calculated by
ECM using the received voltage signal according
to the program. ECM apply the intake air
temperature to adjust the fuel delivery and
