Continuous Memory Self-Test Description

CAUTION: Continuous Memory DTCs should be recorded when retrieved. These DTCs may be used to identify intermittent problems that exist after all KOEO and KOER DTCs have been repaired. Some Continuous Memory DTCs may not be valid after KOEO and KOER DTCs are serviced.

These DTCs are used to diagnose intermittent problems. Continuous Memory DTCs are retrieved after KOER SELF-TEST . These DTCs indicate a fault that may or may not be present at time of testing. These DTCs result from information stored by PCM during continuous self-test monitoring. Use these DTCs for diagnosis only when KOEO SELF-TEST and KOER SELF-TEST result in a DTC 1111 (system pass), and QUICK TEST have been successfully completed. These DTCs indicate faults previously recorded. Fault may or may not be currently present. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION . When using an NGS Tester, it is possible to select RETRIEVE/CLEAR CONTINUOUS DTCs in NGS Tester DIAGNOSTIC DATA LINK. During most diagnostic procedures, it is required that all DTCs be retrieved. It is necessary to use NGS Tester in DIAGNOSTIC TEST MODE. See RETRIEVE/CLEAR CONTINUOUS DTCS for additional information.
