Vehicle control history may be recorded due to the replacement or repair of related parts.
When checking the Vehicle Control History, make sure to record the output codes. Then, clear the Vehicle Control History (RoB) and check it again.
CHECK VEHICLE CONTROL HISTORY (FRONT RADAR SENSOR SYSTEM)
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Body Electrical / Front Radar Sensor / Utility / Vehicle Control History (RoB).
| Tester Display |
|---|
| Vehicle Control History (RoB) |
| Multi-information Display | Code | Tester Display | Description | Diagnostic Note |
|---|---|---|---|---|
| Pre-Collision System Malfunction Visit Your Dealer | X2023 | Front Radar Sensor Optical Axis Not Adjusted | History of millimeter wave radar sensor assembly beam axis not being adjusted. | If this Vehicle Control History (RoB) code is stored, clear the Vehicle Control History (RoB) after performing front beam axis adjustment, and then check that this code is not output again.
|
| - | X2024 | Front Radar Sensor Temporary Unavailable (Vertical Direction Optical Axis Misalignment) | History of millimeter wave radar sensor assembly beam axis misalignment (vertical). | Stored when the vehicle is being driven and the vertical beam axis is calibrated. |
| - | X2025 | Front Radar Sensor Temporary Unavailable (Horizontal Direction Optical Axis Misalignment) | History of millimeter wave radar sensor assembly beam axis misalignment (horizontal). | Stored when the vehicle is being driven and the horizontal beam axis is calibrated. |
| Pre-Collision System Radar Sensor Blocked Unavailable Clean Radar Sensor | X2026 | Front Radar Sensor Dirt | History of system operation being temporarily suspended due to the millimeter wave radar sensor assembly not being able to detect objects. | 1.
Check whether the millimeter wave radar sensor assembly and surrounding area is dirty or obstructed by foreign matter. -
A non-genuine radar sensor cover is installed -
The millimeter wave radar sensor assembly or radar sensor cover and its surrounding area are dirty -
An accessory, such as bull bars, a grille guard, etc., which interferes with millimeter radio waves is installed -
The radar sensor cover or its surrounding area has been painted or has a sticker attached -
There is foreign matter attached to or between the radar sensor cover or millimeter wave radar sensor assembly 2.
If any foreign matter is found around the millimeter wave radar sensor assembly, remove it. 3.
Turn the ignition switch off. 4.
Turn the ignition switch to ON. 5.
Check that "Pre-Collision System Radar Sensor Blocked Unavailable Clean Radar Sensor" is no longer displayed on the multi-information display. 6.
If the message is still displayed, perform beam axis adjustment of the millimeter wave radar sensor assembly.
Cause:
There is foreign matter such as dirt on or around the millimeter wave radar sensor assembly. |
| Pre-Collision System Out of Temperature Range Unavailable See Owner's Manual | X2027 | Front Radar Sensor Outside Guaranteed Operating Temperature | History of system operation being temporarily suspended due to the millimeter wave radar sensor assembly being excessively hot or cold. | 1.
Using the GTS, check "Millimeter-wave Circuit Temperature Protection" in the Data List for Front Radar Sensor. 2.
If the value of "Millimeter-wave Circuit Temperature Protection" is ON, warm or cool the area around the millimeter wave radar sensor assembly. Cause:
The following millimeter wave radar sensor assembly conditions are met: -
After being subjected to an extremely cold environment, the area around the millimeter wave radar sensor assembly is -30°C (-22°F) or less. -
After being subjected to an extremely hot environment, the area around the millimeter wave radar sensor assembly is 70°C (158°F) or more. |
| Pre-Collision System Unavailable See Owner's Manual | X2028 | Front Radar Sensor Outside Guaranteed Operating Voltage | History of system operation being temporarily suspended due to millimeter wave radar sensor assembly power source voltage being excessively high or low. | 1.
If this Vehicle Control History code is output, clear the Vehicle Control History (RoB), drive the vehicle at 5 km/h (3 mph) or more and then check if this Vehicle Control History code is output again. 2.
If output again, check if the voltage between terminals IGB and SGND of the millimeter wave radar sensor assembly is within the specified range. 3.
Using the GTS, check "IG Voltage" in the Data List for Front Radar Sensor. 4.
If the value of "IG Voltage" is ON, check if the voltage between terminals IGB and SGND of the millimeter wave radar sensor assembly is within the specified range. 5.
w/ Stop and Start System: As power for the millimeter wave radar sensor assembly is supplied by the start and stop system, confirm that the start and stop system is not malfunctioning. Cause:
The following millimeter wave radar sensor assembly conditions are met: for HV Model: -
The input voltage decreases to approximately 8 V or less directly after the hybrid system starts. -
The input voltage increases to approximately 16 V or more directly after the hybrid system starts. for Gasoline Model: -
The input voltage decreases to approximately 8 V or less directly after the engine is started. -
The input voltage increases to approximately 16 V or more directly after the engine is started. |
CLEAR VEHICLE CONTROL HISTORY (FRONT RADAR SENSOR SYSTEM)
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Body Electrical / Front Radar Sensor / Utility / Vehicle Control History (RoB).
| Tester Display |
|---|
| Vehicle Control History (RoB) |
According to the display on the GTS, clear the vehicle control history (RoB).
By performing this procedure, all stored Vehicle Control History will be cleared.
CHECK VEHICLE CONTROL HISTORY (AIRBAG SYSTEM)
A part of the control history can be confirmed using the vehicle control history.
