DTC Check / Clear

These scan tools can display pending DTCs and current DTCs. Some DTCs are not stored if the TCM doesn't detect a malfunction during consecutive driving. However, the malfunction detected while a driving is stored as a pending DTC.

1. Connect the intelligent tester to the Controller Area Network Vehicle Interface Module (CAN VIM). Then connect the CAN VIM to the Data Link Connector 3 (DLC3).

2. Turn the engine switch on (IG).
3. Enter the following menus: DIAGNOSIS / OBD / MOBD / ECT / DTC INFO / CURRENT CODES (or PENDING CODE).
4. Confirm the DTCs and freeze frame data and then write them down.
5. Confirm the details of the DTCs (See DIAGNOSTIC TROUBLE CODE CHART  ).
   NOTE: When a symptom has been duplicated using normal mode, use the intelligent tester to check for DTCs. For DTCs that are subject to "2-trip detection logic", perform the following steps:

   Turn the engine switch OFF after the symptom has occurred once. Repeat the process of attempting to duplicate the symptom. When the problem or symptom happens for the second time and a DTC has been recorded, the MIL will illuminate, and the code will be stored.
