Lane Departure Alert System -- Precaution |
| 1.HANDLING PRECAUTION FOR LANE DEPARTURE ALERT SYSTEM |
- The lane departure alert system warns the driver of lane departure in accordance with the road and driving conditions. However, the system alone is not sufficient for maintaining the vehicle position in the lane. Be sure to control the vehicle using the steering wheel to correct the vehicle's path while paying attention to your surroundings and the road ahead. Drive the vehicle in a responsible manner under all circumstances.
- The lane departure alert system operates when the lane departure alert main switch is turned on and lane markers are detected while the vehicle is traveling within the system operating speed. However, depending on the road and driving conditions, the system may not operate or operation may be canceled. Refer to System Description and Precautions for details.
| 2.TROUBLESHOOTING PRECAUTIONS |
If a terminal contact point malfunction or part installation problem occurs, removal and reinstallation of the suspected part may return the system to normal. However, be aware that the normal condition may only be temporary.
Before disconnecting connectors or removing/installing parts, determine the malfunctioning area by checking and writing down the vehicle condition at the time the malfunction occurred (DTC outputs etc.).
Be sure to check for DTCs related to other systems. The lane departure alert system may be influenced by malfunctions in other systems.
| 3.HANDLING PRECAUTIONS |
- Make sure that the engine switch is off unless otherwise specified in the inspection procedure.
- After removal/installation, check for DTCs and confirm that a normal system code is output.
| 4.HANDLING PRECAUTIONS FOR FORWARD RECOGNITION CAMERA |
| 5.REPLACEMENT PRECAUTIONS |
Driving support ECU assembly:
- When replacing the driving support ECU assembly, always replace it with a new one. If a driving support ECU assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
- When replacing the driving support ECU assembly, always replace it with a new one. If a driving support ECU assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
Millimeter wave radar sensor assembly:
- When replacing the millimeter wave radar sensor assembly, always replace it with a new one. When a new millimeter wave radar sensor assembly is installed to the vehicle, it receives vehicle information from the driving support ECU assembly and stores it. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the driving support ECU assembly and millimeter wave radar sensor assembly will not match and a DTC may be stored.
- When the millimeter wave radar sensor assembly is replaced with a new one, adjustment of the radar sensor beam axis must be performed (Click here).
- When replacing the millimeter wave radar sensor assembly, always replace it with a new one. When a new millimeter wave radar sensor assembly is installed to the vehicle, it receives vehicle information from the driving support ECU assembly and stores it. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the driving support ECU assembly and millimeter wave radar sensor assembly will not match and a DTC may be stored.
Forward recognition camera:
- If the forward recognition camera has been replaced with a new one or the windshield glass has been removed and installed, it is necessary to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust (Click here). If the system is turned on without performing Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust, DTC C1AA9 will be stored.
- When replacing the forward recognition camera, 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 replacing or removing/installing the forward recognition camera, do not damage the camera lens or allow it to become contaminated with foreign matter.
- Do not reuse a forward recognition camera that has been dropped or subjected to a strong impact.
- If the forward recognition camera has been replaced with a new one or the windshield glass has been removed and installed, it is necessary to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust (Click here). If the system is turned on without performing Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust, DTC C1AA9 will be stored.
Windshield glass:
- When replacing the windshield glass of a vehicle equipped with a forward recognition camera, make sure to use a Toyota genuine part. If a non-Toyota genuine part is used, the forward recognition camera may not be able to be installed due to a missing bracket or the lane departure alert system may not operate properly due to a difference in the transmissivity or black ceramic border.
Do not attach such as stickers (including transparent stickers) or an antenna items to the outer side of the windshield glass within the area shown in the illustration in front of the forward recognition camera.
- When replacing the windshield glass of a vehicle equipped with a forward recognition camera, make sure to use a Toyota genuine part. If a non-Toyota genuine part is used, the forward recognition camera may not be able to be installed due to a missing bracket or the lane departure alert system may not operate properly due to a difference in the transmissivity or black ceramic border.
