Diagnostic Trouble Codes: Notes

During QUICK TEST, 3 types of Diagnostic Trouble Codes (DTCs) are retrieved: KOEO, KOER and Continuous Memory DTCs. See QUICK TEST  for self-test procedures. DTCs may be cleared from PCM memory after DTCs have been recorded or fault has been repaired. See CLEARING CODES . If fault is still present after clearing DTCs, fault will reset.
