Before replacing the ECM, refer to Service Bulletin.
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.
If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.
Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.
