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 scan tool and/or MIL can also be used, but has limited diagnostic capability. Generic 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.

(1) Refer to appropriate AUTOMATIC TRANSAXLE article in appropriate section. For diagnosis of electronic controlled transaxle.

(2) Check cooling system and thermostat if engine coolant temperature does not reach 176°F (80°C) after driving 20 minutes.

(3) See appropriate BODY CONTROL COMPUTER TESTS article in ACCESSORIES & EQUIPMENT section.

(4) Replace Powertrain Control Module (PCM). Perform TEST VER-2A.
