Diagnostic Trouble Codes: Notes

NOTE: Before clearing DTCs, perform On-Board Diagnostic (OBD) System Check. See the ENGINE CONTROLS - BASIC TESTING 5.7L article. Record FREEZE FRAME and FAILURE RECORDS for reference during testing. Data will be erased when DTCs are cleared. If PCM/VCM is replaced, NEW PCM/VCM must be programmed using special manufacturer's equipment.
