Lexus NX: Freeze Frame Data
FREEZE FRAME DATA
DESCRIPTION
(a) When a front camera system DTC is stored, the forward recognition camera stores the current vehicle (ECU or sensor) state as Freeze Frame Data.
CHECK FREEZE FRAME DATA
(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 / Trouble Codes.
Chassis > Front Recognition Camera > Trouble Codes(e) According to the Techstream display, select a DTC that stored freeze frame data.
(f) Read the freeze frame data recorded when the DTC was stored.

|
| 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 |
|
| Vehicle Information (Steering Wheel Position) | Vehicle information (steering wheel installation location) stored by forward recognition camera | Unknown, Left or Right | Steering wheel installation location |
|
| HV Equipped Information | Vehicle information (engine) stored by forward recognition camera | Non-HV or HV | Non-HV: Gasoline Model HV: HV Model |
|
| Steering Vibrator Equipped Information | Whether steering vibration is installed or not | Absent or Present | Absence: Not installed Presence: Installed |
|
| 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 |
|
| Front Recognition Camera Low Voltage | Whether low voltage malfunction of forward recognition camera exists or not | Not Low Voltage or Low Voltage | Not Low Voltage | If this item is "Low Voltage", the camera may have been temporarily unavailable |
| Front Recognition Camera High Voltage | Whether high voltage malfunction of forward recognition camera exists or not | Not High Voltage or High Voltage | Not High Voltage | If this item is "High Voltage", the camera may have been temporarily unavailable. |
| Front Recognition Camera Low Temperature | Whether low temperature malfunction of forward recognition camera exists or not | Not Low Temperature or Low 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 |
HINT: In summertime, the windshield glass may reach 100°C (212°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 |
| Front Recognition Camera Optical Axis Misalignment (X) | Whether beam axis misalignment (horizontal direction) of forward recognition camera exists or not | Not Axis Misalignment or Axis Misalignment | Not Axis Misalignment | Camera beam axis misalignment (horizontal direction) may have occurred for some reason. Confirm that the cause of the beam axis misalignment is not inside the vehicle |
| Front Recognition Camera Optical Axis Misalignment (Y) | Whether beam axis misalignment (vertical direction) of forward recognition camera exists or not | Not Axis Misalignment or Axis Misalignment | Not Axis Misalignment | Camera beam axis misalignment (vertical direction) may have occurred for some reason. Confirm that the cause of the beam axis misalignment is not inside the vehicle. |
| Front Recognition Camera Roll Angle Optical Axis Misalignment | Whether beam axis misalignment (roll direction) of forward recognition camera exists or not | Not Axis Misalignment or Axis Misalignment | Not Axis Misalignment | Camera beam axis misalignment (roll direction) may have occurred for some reason. Confirm that the cause of the beam axis misalignment is not inside the vehicle. |
| 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 |
|
| 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.) |
