Continuous Memory DTCs

WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 1999 Mercury Tracer, 1999 Mercury Sable, 1999 Mercury Mystique, 1999 Mercury Mountaineer, and 1999 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

Continuous Memory DTCs are retrieved after performing KOER ON-DEMAND SELF-TEST. Unlike KOEO or KOER self-tests, which can only be activated on-demand, Continuous Memory Self-Test is always active. A fault may or may not be present at time of checking for Continuous Memory DTCs. This self-test is helpful in diagnosing intermittent problems.

After noting and/or repairing fault, clear DTCs from memory. See CLEARING CODES . Intermittent faults may be caused by a sensor, connector or wiring-related problem. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES - EEC-V article.

NOTE: 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 DTC faults may not be valid after KOEO and KOER DTCs are serviced.
