Current Diagnostic Trouble Codes (DTCs)

When the IPC determines that the test conditions and the failure conditions for a particular DTC are true and the condition is during the current ignition cycle, the IPC sets the code as a Current DTC. All DTC(s) remain current until the next fault free ignition cycle and the IPC finds the test conditions are true and the failure conditions are false. The Current code then will become a History code only.
