Diagnostic Trouble Code Definitions

If a "P" series DTC appears that is not listed in DIAGNOSTIC TROUBLE CODE DEFINITIONS table, see DTC P1001: DATA LINK CONNECTOR MALFUNCTION OR DTC NOT LISTED  under DIAGNOSTIC TESTS. On some models, PCM is capable of storing some body DTCs. If any "B", "C" or "U" series DTCs are retrieved (example DTC B1213, C1702 or U2195), go to appropriate MODULE COMMUNICATIONS NETWORK article in ACCESSORIES & EQUIPMENT to determine test to perform.
