ERASE CODES
The vehicle service manual may recommend erasing Continuous Memory Codes
from vehicle’s memory, and then drive 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.
