Ford Historic Self-Test Routines

Erase Codes

The vehicle service manual may recommend erasing Continuous Memory Codes from vehicle’s memory, and then driving vehicle to duplicate the malfunction before beginning a diagnostic test. If KOEO codes were read using Fast Codes, the memory codes have already been erased.

Only Continuous Memory Codes can be erased from the vehicle without repairing the fault. To remove KOEO and KOER Codes, the fault must be repaired since they only exist when a fault exists.
