DTC's are catagorized by type. The type will indicate the action the DTC will take in storing a failure and illuminating the MIL.
When a Type A DTC diagnostic fails, the DTC is set immediately and the Malfunction Indicator Lamp (MIL) is illuminated. When a Type B DTC diagnostic fails, the Malfunction Indicator Lamp (MIL) will illuminate if the fault is present after two consecutive drive trips. When a Type C DTC diagnostic fails, the DTC will set immediately but will not illuminate the Malfunction Indicator Lamp (MIL). For some Type C DTC's only a message will appear on the Driver Information Center (DIC). Type C DTC's that DO NOT display a message were formerly referred to as Type D.
