Note
If the pre-crash safety city sensor has been replaced, or the windshield glass has been replaced or removed/installed, be sure to perform Recognition Camera/Target Position Memory and Recognition Camera Axis Adjust. If not performed, DTC will be stored when the system is turned on.
When replacing the pre-crash safety city sensor, replace it with a new one. If a pre-crash safety city sensor which was installed to another vehicle is used, the information stored in the pre-crash safety city sensor will not match the information from the vehicle and, as a result, a DTC may be stored.
