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) Turn the power switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the power switch on (IG).
(d) Turn the Techstream on.
(e) Enter the following menus:
(1) Body Electrical / Main Body / Data List.
(2) Chassis / Front Recognition Camera / Data List.
(f) Read the Data List according to the display on the Techstream.

| Tester Display | Measurement Item | Range | Normal Condition | Diagnostic Note |
|---|---|---|---|---|
| Front Recognition Camera High Temperature 2 | Whether high temperature malfunction of forward recognition camera exists or not | Not High Temperature or High Temperature | Not High Temperature: Approximately 65°C (149°F) or less High Temperature: Approximately 65°C (149°F) or higher | If this item is "High Temperature", the automatic high beam system 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. HINT: In summertime, the windshield glass may reach 100°C (212°F) or higher |
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) Turn the power switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the power switch on (IG).
(d) Turn the Techstream on.
(e) Enter the following menus: Body Electrical / Combination Meter / Active Test.
(f) Perform the Active Test according to the display on the Techstream.
Body Electrical > Combination Meter > Active Test| Tester Display | Measurement Item | Control Range | Diagnostic Note |
|---|---|---|---|
| Automatic High Beam Indicator | Automatic high beam indicator light | OFF or ON | - |
