Toyota Camry (XV70): Problem Symptoms Table
PROBLEM SYMPTOMS TABLE
NOTICE:
- 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 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.

- 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.
HINT:
- If no problem symptoms are found when a DTC is output in the DTC check on the lane tracing assist system, check each symptom by checking the suspected areas in the order they are listed.
- Before performing failure diagnosis according to the following inspection points, check the forward recognition camera system power source circuit fuses and relays.
