Diagnosis By Symptom
A pass code (11-10-11), indicates there are no active codes in the KOEO or KOER SELF-TEST. If driveability symptoms still exist and the EEC system is still suspect, use the SYMPTOM DIAGNOSTIC TABLES for referral to the appropriate CIRCUIT TEST. See DIAGNOSIS BY SYMPTOM (SYMPTOM-TO-CIRCUIT TEST MENU) table.
