Test NTC-1: No Trouble Code Test Menu
No Trouble Code (NTC) tests may be performed if a starting, driveability, scan tool communication problem exists or if sent here from another test. Before performing any NTC tests, ensure no DTCs are present. See RETRIEVING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM. If any DTCs are present, repair DTCs before continuing. If no DTCs are present, select symptom which most accurately describes problem and determine what NTC test should be performed. See NO TROUBLE CODE TEST MENU table.
