NORMAL Mode Code Retrieval

  1. Connect scan tool to Data Link Connector (DLC) No. 3. See Figure. DLC No. 3 is located under left side of instrument panel. Turn ignition on with engine off. Turn scan tool on. Using scan tool manufacturer's instructions, check for DTCs and freeze-frame data.
  2. 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.
  3. If any DTCs are present, perform appropriate diagnostic 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.
  4. After repairs for DTC have been completed, DTCs must be cleared from ECM memory. See CLEARING DIAGNOSTIC TROUBLE CODES .
