As a result, 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.
