Continuous Memory DTCs

These DTCs result from information stored by PCM during continuous self-test monitoring. Use these DTCs for diagnosis only when KOEO ON-DEMAND SELF-TEST and KOER ON-DEMAND SELF-TEST result in a system pass (DTC P1111 on Federal Models or no DTCs present on Calif. Models) and all steps under QUICK TEST have been successfully completed. These DTCs indicate faults previously recorded. Fault may or may not be currently present. See DIAGNOSTIC TROUBLE CODE (DTC) REFERENCE CHART .
