Problem Symptoms Table [10/2022 - ]
WARNING: This page is about a different car, the 2025 Toyota RAV4, 2024 Toyota RAV4 Prime, 2023 Toyota RAV4 Prime, and 2022 Toyota RAV4 Prime. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Before replacing the main body ECU (multiplex network body ECU), refer to Registration.
Refer to REGISTRATION [12/2021 - ]
- When replacing the combination meter assembly, always replace it with a new one. If a combination meter 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 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. As a result, a DTC may be stored.
- When the forward recognition camera is replaced with a new one, 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) [10/2022 - ]
Sequential Recognition:
Refer to TARGET ADJUSTMENT(SEQUENTIAL RECOGNITION) [10/2022 - ]
Driving Adjustment:
Refer to DRIVING ADJUSTMENT [10/2022 - ]
