Ford Historic Self-Test Routines

Erase Codes

The vehicle service manual may recommend erasing Continuous Memory Codes from vehicle’s memory, and then drive vehicle to duplicate the malfunc- tion 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 repair- ing the fault. To remove KOEO and KOER Codes, the fault must be repaired since they only exist when a fault exists.
