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.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Radar Cruise 1*1 or Radar Cruise 2*2 / Data List.
- *1: Output from the ECM
- *2: Output from the millimeter wave radar sensor assembly
(e) Cruise Control:
Read the Data List according to the display on the Techstream.
HINT:
- If any DTCs are output, the value for a measurement item may be incorrect.
- If any DTCs are output, perform troubleshooting accordingly. After repair, confirm relevant values using the 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.
Perform Active Test according to the display on the Techstream.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Radar Cruise 2 / Active Test.
(e) Perform Active Test according to the display on the Techstream.
HINT:
The ignition switch must be turned to ON to proceed with the Active Test using the Techstream.
