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 engine switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus:

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

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

(3) for AFS (Sub): Body Electrical / AFS (Sub) / Data List.

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

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

(6) for Front Recognition Camera (Front Lighting Control): Body Electrical / Front Recognition Camera (Front Lighting Control) / Data List.

(7) for Front Recognition Camera: Chassis / Front Recognition Camera / Data List.

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