Toyota Avalon (XX50) 2019-2022 Service & Repair Manual: Data List / Active Test

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: Powertrain / Radar Cruise 1*1 or Radar Cruise 2*2 / Data List.

  • *1: Output from the hybrid vehicle control ECU
  • *2: Output from the driving support ECU assembly

(e) Radar Cruise 1:

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.
