Lexus NX: 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: Body Electrical / AFS / Data List.
(e) Read the Data List according to the display on the Techstream.

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) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / AFS / Active Test.
(e) Perform the Active Test according to the display on the Techstream.
Body Electrical > AFS > Active Test| Tester Display | Measurement Item | Control Range | Diagnostic Note |
|---|---|---|---|
| Drive The Leveling Motor | Headlight swivel and leveling motor operation | Up, Down or Stop | Perform with the vehicle stopped, power switch on (READY) and low beam headlights illuminated. |
| Drive Swivel Motor LH | Right headlight swivel and leveling motor (swivel function) left or right direction rotation | OFF or ON | Perform with the vehicle stopped, power switch on (READY) and low beam headlights illuminated. |
| Drive Swivel Motor RH | Left headlight swivel and leveling motor (swivel function) left or right direction rotation | OFF or ON | Perform with the vehicle stopped, power switch on (READY) and low beam headlights illuminated. |
| AFS OFF Indicator | "Headlight System Malfunction Visit Your Dealer" display | OFF or ON | - |
