The DTCs are grouped into several types. Each type has a unique set of characteristics for the MIL operation, the DTC storage, and the DTC clearing. The following list contains a brief summary of the types and the associated properties of each:

•	Type A is emissions related. The MIL illuminates, the DTC stores on the first fail and the Freeze Frame data is captured.

•

Type B is emissions related. If the fault is active for 2 consecutive driving cycles (the misfire and the fuel trim DTCs differ slightly), the MIL illuminates, the DTC stores and the Freeze Frame data is captured at the time of the second fail. At the time of the first fail, the MIL is not illuminated and no Freeze Frame data records. The DTC will appear in the memory as pending. If the next trip reports a pass, the DTC will no longer appear.

•	Type C is non-emissions related, does not turn on the MIL, but may turn on an auxiliary service lamp if the vehicle is so equipped. The DTC stores at the time of the first fail.
