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.
Chassis > Front Recognition Camera > Data List| Tester Display | Measurement Item | Range | Normal Condition | Diagnostic Note |
|---|---|---|---|---|
| Total Distance Traveled | - | - | - | Not applicable |
| Total Distance Traveled - Unit | - | - | - | Not applicable |
| VGRS ECU Equipped Information | Variable gear ratio steering system function availability | Absence or Presence | Absence: Variable gear ratio steering system absence Presence: Variable gear ratio steering system presence | 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. |
| DRS System Equipped Information | Dynamic rear steering system function availability | Absence or Presence | Absence: Dynamic rear steering system absence Presence: Dynamic rear steering system presence | 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. |
| Vehicle Information (Steering Wheel Position) | Vehicle information (steering wheel installation location) stored by forward recognition camera | Unknown, Left or Right | Steering wheel installation location | 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. |
| HV Equipped Information | Vehicle information (engine) stored by forward recognition camera | Non-HV or HV | Non-HV: Gasoline Model HV: HV Model | 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. |
| Steering Vibrator Equipped Information | Whether steering vibration is installed or not | 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. |
| Buzzer (Line) Equipped Information | 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 |
|
| 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 |
|
| 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 or adaptive 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 |
| Heater Available Information | Whether a hot-wire heater exists in the forward recognition camera or not | Absence or Presence | Absence: w/o Heater Wire Heater Presence: w/ Heater Wire Heater | The forward recognition camera checks conductivity with the hot-wire heater. If this item is "Absence", a new forward recognition camera may have been installed with the hot-wire heater disconnected. |
| Heater Control Permit | The control permission status of the hot-wire heater in the forward recognition camera | Not Allow or Allow | Not Allow: Hot-wire heater control not permitted Allow: Hot-wire heater control permitted | If this item is "Not Allow", the following statuses are likely.
|
| Heater Control | The control status of the hot-wire heater in the forward recognition camera | Not Control or Under Control | Not Control: Hot-wire heater not controlled Under Control: Hot-wire heater controlled | If the hot-wire heater control permission item is "Allow" and the outside temperature is 10°C (50°F) or less, this item will repeatedly switch between "Not Control" and "Under Control". (For vehicles with whole surface deicers, this item will remain "No Control" when the whole surface deicer is in use.) |
