Lexus NX: Data List / Active Test

DATA LIST / ACTIVE TEST

DATA LIST

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.

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.

(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.

Whether or not a buzzer is installed to the forward recognition camera connected by direct line

Absent or Present

Absence: Not installed

Presence: Installed

If a display different from vehicle specification is output, a forward recognition camera that was used with a different vehicle was installed, or the forward recognition camera may be malfunctioning.

Front Recognition Camera Low Temperature

Whether low temperature malfunction of forward recognition camera exists or not

Not High Temperature or High Temperature

Not Low Temperature: Approximately -30°C (-22°F) or higher

Low Temperature: Approximately -30°C (-22°F) or less

  • If this item is "Low Temperature", it will display that the camera is temporarily unavailable.
  • If this item is "Low Temperature", X2016 is output in the vehicle control history.

Front Recognition Camera High Temperature 1

Whether high temperature malfunction of forward recognition camera exists or not

Not High Temperature or High Temperature

Not High Temperature: Approximately 80°C (176°F) or less

High Temperature: Approximately 80°C (176°F) or higher

  • If this item is "High Temperature", the camera will be temporarily unavailable. If this does not improve even if the inside of the vehicle is left cooled for at least 10 minutes, the forward recognition camera may be malfunctioning.
  • If this item is "High Temperature", X2016 is output in the vehicle control history.
