Service Code Descriptions: Notes
WARNING: This page is about a different car, the 1990 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
There are 3 types of service codes retrieved in the QUICK TEST procedures during Key On Engine Off (KOEO) and Key On Engine Running (KOER) Self-Test modes. They are KOEO, KOER, and Continuous Memory codes. Codes may be cleared from the ECA memory after they have been recorded or repaired. See CLEARING CODES in this article.
