HINT:
- 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, the 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 the inspection again, even if the DTCs
were not output when rechecking for DTCs.
