1.	CHECK DTC OUTPUT

(a) Clear the DTCs.

(b) Recheck for DTCs and check that no DTCs are output.

HINT:

If CAN communication system DTCs are stored, they may also be stored in other systems.
If the CAN communication system has been inspected and repaired in other systems, 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 though the DTC was not output when rechecking for DTCs.
