Continuous Memory Codes (Soft Faults)
These codes indicate a fault that may or may not be present at time of testing. These codes are used to diagnose intermittent problems. Continuous Memory Codes are retrieved during KOEO SELF-TEST. Some codes may turn on MIL or CHECK ENGINE light. Corresponding soft trouble code will be retained in ECA memory. If fault does not reoccur within 40 warm-up cycles (80 cycles on some models), ECA will automatically clear code.
Technician may clear service codes from memory. See CLEARING CODES . Intermittent faults may be caused by a sensor, connector or wiring-related problems. See INTERMITTENTS in TESTS W/O CODES article in the ENGINE PERFORMANCE Section.
CAUTION:
Continuous Memory Codes should be recorded when retrieved during KOEO SELF-TEST. These codes may be used to identify intermittent problems that exist after all KOEO and KOER codes have been repaired and a Code 11 or 111 (pass code) has been obtained. Failure to follow this procedure may result in unnecessary testing. Some Continuous Memory Codes faults may not be valid after KOEO and KOER codes are repaired.
