Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Caution / Notice / Hint
- When replacing the millimeter wave radar sensor assembly, always replace it with a new one. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the millimeter wave radar sensor assembly will not match the information from the vehicle and a DTC may be stored.
- When the millimeter wave radar sensor assembly has been replaced with a new one, it is necessary to perform millimeter wave radar sensor assembly beam axis alignment and to clear the vehicle control history. Before performing the Driving Adjustment, make sure to read Before Starting Driving Adjustment.
HINT:
Beam axis alignment of the millimeter wave radar sensor assembly can be performed using either Triangle Target, Flat Surface Target or Driving Adjustment.
Triangle Target: Refer to TARGET ADJUSTMENT (TRIANGLE TARGET) [10/2022 - ]
Flat Surface Target: Refer to TARGET ADJUSTMENT (FLAT SURFACE TARGET) [10/2022 - ]
Driving Adjustment: Refer to DRIVING ADJUSTMENT [10/2022 - ]
- When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle and a DTC may be stored.
- When the forward recognition camera is replaced with a new one or the windshield glass is replaced or removed/installed, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history for each system.
HINT:
Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.
One Time Recognition: Refer to TARGET ADJUSTMENT (ONE TIME RECOGNITION) [09/2020 - ]
Sequential Recognition: Refer to TARGET ADJUSTMENT (SEQUENTIAL RECOGNITION) [09/2020 - ]
Driving Adjustment: Refer to DRIVING ADJUSTMENT [09/2020 - ]
- When the forward recognition camera is replaced, update the ECU security key.
Refer to UPDATE ECU SECURITY KEY [11/2023 - ]
