Diagnostic Trouble Code Definitions: Notes
WARNING: This page is about a different variant/trim than selected.
NOTE:
Prior to performing any system test, see HOW TO USE SYSTEM TESTS under SYSTEM TESTS. If instructed to replace Powertrain Control Module (PCM) after performing a system test, new PCM must be programmed. See PROGRAMMING PCM .
If a DTC appears with an "x" in the numerator (example DTC P071x), "x" denotes any number between 0-9. If a "P" series DTC appears that is not listed in DIAGNOSTIC TROUBLE CODE DEFINITIONS table, diagnose by symptom in TROUBLE SHOOTING - NO CODES - DIESEL - 7.3L article for symptom diagnosis. 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.
