Continuous Memory DTCs
WARNING: This page is about a different car, the 2000 Mercury Mystique, 2000 Ford Pickup, 2000 Ford F550 Super Duty, 2000 Ford F450 Super Duty, and 2000 Ford Contour. 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 faults.
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 (BI-FUEL) article.
NOTE:
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 DTC faults may not be valid after KOEO and KOER DTCs are serviced.
