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 power switch to on (IG).

(d) Enter the following menus:

(1) for Wiper: Body Electrical / Wiper / Data List.

(2) for Main Body: Body Electrical / Main Body / Data List.

(3) for Combination Meter: Body Electrical / Combination Meter / Data List.

(4) for Steering Angle Sensor: Chassis / Steering Angle Sensor / Data List.

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

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 power switch to on (IG).

(d) Enter the following menus:

(1) for Wiper: Body Electrical / Wiper / Active Test.

(2) for Main Body: Body Electrical / Main Body / Active Test.

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