Record any DTCs and freeze-frame data displayed for system diagnosis. If driveability problem exists and no DTCs are present, go to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom.
If any DTCs are present, perform appropriate circuit test. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION table. For more information on freeze-frame data, see FREEZE-FRAME DATA under INTRODUCTION. For information on 2-trip detection logic codes, see TWO-TRIP DETECTION LOGIC under INTRODUCTION.
After repairs for DTC have been completed, DTCs must be cleared from ECM memory. See CLEARING DIAGNOSTIC TROUBLE CODES .
