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 on (IG). (c) Turn the Techstream on. (d) Enter the following menus: Chassis / Front Recognition Camera / Data List.
(e) Read the Data List according to the display on the Techstream. Chassis > Front Recognition Camera > Data List

- | 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 on (IG).
(c) Turn the Techstream on. (d) Enter the following menus: Chassis / Front Recognition Camera / Active Test.
(e) Perform Active Test according to the display on the Techstream. HINT:
The power switch must be turned on (IG) to proceed with the Active Test using the Techstream. Chassis > Front Recognition Camera > Active Test
