      Tech Tips


      • 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.
