DTC Check/Clear

DTCs which are stored in the ECM can be displayed with the intelligent tester.

The tester can display pending DTCs and current DTCs. Some DTCs are not stored if the ECM does not detect a malfunction during consecutive driving cycles. However, malfunctions detected during a single driving cycle are stored as pending DTCs.
