| CHECK DTC |
DTCs which are stored in the ECM can be displayed with the intelligent tester and generic OBD scan tool.
These scan tools can display pending DTCs and current DTCs. Some DTC aren't stored if the ECM doesn't detect a malfunction during consecutive driving. However, the detected malfunction during once driving is stored as pending DTC.
Connect the intelligent tester to the Data Link Connector 3 (DLC3).
Turn the engine switch on (IG).
Enter the following menus: Enter / Powertrain / ECT / DTC / Current (or Pending).
Confirm the DTCs and freeze frame data and then write them down.
Confirm the details of the DTCs .
- NOTICE:
- When simulating a symptom with the scan tool to check the DTCs, use normal mode. For codes on DIAGNOSTIC TROUBLE CODE CHART which are subject to "2-trip detection logic", perform the following actions.
Turn the engine switch off after the symptom is simulated once. Then repeat the simulation process again. When the problem has been simulated twice, the MIL illuminates and the DTCs are recorded in the ECM.
