Diagnostic Trouble Codes (DTCs) are retrieved using QUICK TEST. Three types of DTCs: KOEO, KOER and continuous memory DTCs are stored. See RETRIEVING DIAGNOSTIC TROUBLE CODES (QUICK TEST) under SELF-DIAGNOSTIC SYSTEM. During QUICK TEST, PCM performs 3 self-tests to retrieve DTCs. See RETRIEVING DTCS . DTCs may be cleared from PCM memory after they have been recorded or repaired. See CLEARING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM.
