Diagnostic Trouble Code (DTC) Identification

NOTE: When using MIL to retrieve DTCs, some DTCs have more than one meaning. The MIL is unable to distinguish between different failures for a specified component. For example, there are 4 different possible failures for the downstream oxygen sensor system, but the MIL can only identify an downstream oxygen sensor failure by flashing a DTC 21. See DTC MESSAGES & CODES  table.
NOTE: If using Chrysler's Diagnostic Readout Box (DRB-III) scan tool, scan tool has ability to display all Diagnostic Trouble Codes (DTCs). Generic OBD-II scan tool and/or MIL can also be used, but has limited diagnostic capability. Generic OBD-II scan tool is not be able to identify all possible DTCs. As an example, generic scan tool may not be able to identify or display a DTC for a malfunctioning A/C clutch relay circuit, A/C pressure sensor, Auto Shutdown (ASD) relay circuit, charging system voltage circuit or knock sensor circuit. See DTC MESSAGES & CODES table.
