The DTCs are grouped into several types. Each type has a unique set of characteristics for telltale operation, DTC storage, and DTC clearing. The following list contains a brief summary of the DTC 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 drive cycle, the MIL illuminates, the DTC is stored and the Freeze Frame data is captured at the time of the second fail. At the time of the first fail, the MIL does not illuminate and no Freeze Frame data records. The DTC will appear in memory as pending. If the next trip reports a pass, the DTC is gone. |
| • | Type C is non-emission related and does not turn on the MIL, but will either illuminate the STL lamp or flash the sport mode lamp. The DTC stores at the time of the first fail. |
| • | Type D is non-emissions related, does not illuminate any lamps. The DTC stores at the time of the first fail. |
