      Tech Tips


      • DTC C1647 is stored when a malfunction signal sent from the vehicle stability control system is detected.

      • If the malfunctioning part has been repaired or replaced before rechecking for DTCs, DTC C1647 will not be output again.

      • If DTC C1647 is 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.
