If CAN communication system DTCs are stored, they may also be stored for other systems.
 
                        - 
If the CAN communication system has been inspected and repaired, these DTCs will not be output when rechecking for DTCs.
 
                        - 
If these DTCs are output frequently, duplicate the conditions that cause the problem symptoms and perform troubleshooting again, even though the DTC was not output when rechecking for DTCs.
