DATA LIST / ACTIVE TEST

DATA LIST

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

HINT:

Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus:

(1) for Air Conditioner: Body Electrical / Air Conditioner / Data List.

(2) for Engine: Powertrain / Engine / Data List.

(3) for Hybrid Control: Powertrain / Hybrid Control / Data List.

(e) Read the Data List according to the display on the Techstream.

Coolant Temperature

Engine coolant temperature

Min.: -40°C (-40°F)

Max.: 140°C (284°F)

75 to 100°C (167 to 212°F): After warming up

This is the engine coolant temperature.

HINT:

After warming up the engine, the engine coolant temperature will be 75 to 100°C (167 to 212°F).
After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal.
If the value is -40°C (-40°F), or higher than 135°C (275°F), the sensor circuit is open or shorted.
Check if the engine overheats if the value indicated is higher than 135°C (275°F).

ACTIVE TEST

HINT:

Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus:

(2) for Engine: Powertrain / Engine / Active Test.

(3) for Hybrid Control: Powertrain / Hybrid Control / Active Test.

(e) Perform the Active Test according to the display on the Techstream.
