Note
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.
Tech Tips
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.
DATA LIST
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Body Electrical / HL AutoLeveling / Data List / All Data.
According to the display on the GTS, read the Data List.

ACTIVE TEST
Tech Tips
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.
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Body Electrical / HL AutoLeveling / Active Test.
According to the display on the GTS, perform the Active Test.
| Tester Display | Measurement Item | Control Range | Diagnostic Note |
|---|---|---|---|
| Drive The Leveling Motor | Operates the headlight leveling motor (Perform with the vehicle stopped, engine switch on (IG) and low beam headlights illuminated) | Up, Down or Stop | - |
