Toyota Yaris: Dynamic Radar Cruise Control System / Data List / Active Test
DATA LIST / ACTIVE TEST
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.
- When diagnosing symptoms such as hesitation, rough idle, or other small symptoms using vehicle control history, compare data extracted from the same vehicle model in the same conditions and make sure to analyze all data in its entirety before making a diagnosis.
DATA LIST
HINT:
Using the GTS 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) 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
(b) Read the Data List according to the display on the GTS.

ACTIVE TEST
HINT:
Using the GTS 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) Perform the Active Test according to the display on the GTS.
