In addition, application of Diagnostic Trouble Codes (DTC) which is required by ISO 14230-4 recorded in the ECM memory. If malfunctions do not happen again in 3 trips in a row, MIL DTC will automatically die but remain recorded in the ECM memory.
To check the DTCs, connect the intelligent tester to Data Link Connector 3 (DLC3) on the vehicle.
