The LTA indicator output request signal is sent from the forward recognition camera to the combination meter assembly via CAN communication.
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 perform beam axis adjustment for the forward recognition camera and clear the vehicle control history for each system.
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, be sure to replace it with a new part. If a device that was installed in another vehicle is used, the information stored in the combination meter assembly will not match the information from the vehicle, and may cause a DTC to be output.
