Continuous Memory Self-Test

WARNING: This page is about a different car, the 2001 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Continuous memory DTCs should be recorded when retrieved. These DTCs may be used to identify intermittent faults 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 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 SYSTEM PASS and all steps in QUICK TEST are successfully completed. These DTCs indicate faults previously recorded. Fault may or may not be currently present. See DIAGNOSTIC TROUBLE CODE DEFINITIONS . After noting and/or repairing concern, clear DTCs from memory. See CLEARING DIAGNOSTIC TROUBLE CODES . Intermittent faults may be caused by a sensor, connector or wiring-related concern.

Turn ignition switch to OFF position. Ensure test equipment is properly attached. Program NGS tester following manufacturers instructions. Follow operating instructions from NGS tester menu.
