Powertrain Control Module (PCM)

Description:

Diagnostic Chart:

DTC's are categorized 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 DTCs only a message will appear on the Driver Information Center (DIC). Type C DTCs that DO NOT display a message were formerly referred to as Type D. For more information regarding DTC types refer to Powertrain Control Module Description and Operation.

Export Vehicle DTC Type Information

The Service information refers to the domestic (federal) calibration package. The domestic calibration is for vehicles sold in the United States, Canada and Japan. For unleaded EXPORT calibration vehicles some DTCs have changed type. For leaded export vehicles some DTCs have been turned off. These changes are NOT reflected in the service information of the DTCs Diagnostic Support Information. Export calibration vehicles are only referenced in the DTC List table.
