HINT: Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition. One Time Recognition: Sequential Recognition: |
| Radar Cruise Control Unavailable See Owner's Manual | X2015 | Front Recognition Camera Dirt | System operation was temporarily suspended due to the forward recognition camera not being able to detect objects. | Refer to vehicle control history code X2015 in Front Camera System. |
| Radar Cruise Control Unavailable | X2016 | Front Recognition Camera Outside Guaranteed Operating Temperature | System operation was temporarily suspended due to the forward recognition camera being excessively hot or cold. | Refer to vehicle control history code X2016 in Front Camera System. |
| Radar Cruise Control Unavailable | X2017 | Front Recognition Camera Outside Guaranteed Operating Voltage | System operation was temporarily suspended due to the forward recognition camera power source voltage being excessively high or low. | Refer to vehicle control history code X2017 in Front Camera System. |
| Cruise Control Malfunction Visit Your Dealer | X201D | Front Recognition Camera System Software Malfunction | The forward recognition camera detected a specification information malfunction. | Refer to How to Proceed with Troubleshooting in Front Camera System. |
| Radar Cruise Control Unavailable | X201F | Front Recognition Camera Temporary Unavailable (Front Recognition Camera Recognition Stop) | The forward recognition camera operation was suspended. | Refer to How to Proceed with Troubleshooting in Front Camera System. |
| Cruise Control Malfunction Visit Your Dealer | X2020 | Front Radar Sensor Destination Malfunction | The forward recognition camera received a destination information malfunction signal from the millimeter wave radar sensor assembly. | Refer to How to Proceed with Troubleshooting in Front Radar Sensor System. |
| Cruise Control Malfunction Visit Your Dealer | X2021 | Front Radar Sensor Malfunction | The forward recognition camera received a malfunction signal from the millimeter wave radar sensor assembly. | Refer to How to Proceed with Troubleshooting in Front Radar Sensor System. |
| Cruise Control Malfunction Visit Your Dealer | X2022 | Front Radar Sensor Optical Axis Misalignment Malfunction | The forward recognition camera received a beam axis misalignment malfunction signal from the millimeter wave radar sensor assembly. | Perform beam axis adjustment for the millimeter wave radar sensor assembly. |
| Cruise Control Malfunction Visit Your Dealer | X2023 | Front Radar Sensor Optical Axis Not Adjusted | The forward recognition camera received a beam axis unadjusted signal from the millimeter wave radar sensor assembly. | If this history is output, delete the vehicle control history after adjusting the beam axis and check that the history is not output again. |
| Radar Cruise Control Unavailable See Owner's Manual | X2026 | Front Radar Sensor Dirt | The forward recognition camera received a millimeter wave radar sensor assembly dirty malfunction signal from the millimeter wave radar sensor assembly. | Refer to vehicle control history code X2026 in Front Radar Sensor System. |
| Radar Cruise Control Unavailable | X2027 | Front Radar Sensor Outside Guaranteed Operating Temperature | The forward recognition camera received a temperature malfunction signal from the millimeter wave radar sensor assembly. | Refer to vehicle control history code X2027 in Front Radar Sensor System. |
| Radar Cruise Control Unavailable | X2028 | Front Radar Sensor Outside Guaranteed Operating Voltage | The forward recognition camera received a voltage malfunction signal from the millimeter wave radar sensor assembly. | Refer to vehicle control history code X2028 in Front Radar Sensor System. |
| Radar Cruise Control Unavailable | X2029 | Front Radar Sensor Temporary Unavailable (Optical Axis Misalignment) | The forward recognition camera received a beam axis misalignment signal from the millimeter wave radar sensor assembly. | Perform beam axis adjustment for the millimeter wave radar sensor assembly. |
| Radar Cruise Control Unavailable | X20AE | Radar Cruise Control Invalidation for Undetectable Vehicle Traveling Directly Ahead | The forward recognition camera stores a cancellation history of control of vehicle speed when the dynamic cruise control system temporarily could not detect the preceding vehicle due to environmental influence such as bad weather. |
