Continuous Memory DTCs are stored in vehicle’s memory at the time of
occurrence during continuous self-test monitoring. They will remain there
until the problem does not reoccur within 40 warm-up cycles, Fast KOEO
codes have been read, or the Erase Codes function has been run. Contin-
uous memory codes follow the KOEO codes in the data stream.

The DTCs are transmitted in two formats; both transmit the same information:

Slow Codes are regular service codes that allow the user to identify the
faults with an analog voltmeter or the check engine light. Slow codes are
transmitted within 3 minutes.
