CHECK Mode Code Retrieval (Toyota Hand-Held Tester Only)

NOTE: If ignition switch is turned from ON to ACC or OFF position, all DTCs and freeze-frame data will be erased. DO NOT switch modes until all DTCs and freeze-frame data are recorded.
  1. Ensure vehicle battery is fully charged. Apply parking brake. Shift transmission/transaxle into Neutral (M/T) or Park (A/T). Turn A/C and all accessories off. Ensure throttle valve is fully closed. Turn ignition off. Connect scan tool to Data Link Connector (DLC) No. 3. Turn ignition on with engine off. Turn scan tool on.
  2. Switch scan tool from NORMAL mode to CHECK mode. CHECK mode is operational if MIL on instrument cluster flashes. Start engine. If no DTCs are present, MIL will turn off. Try to simulate conditions of driveability complaint described by customer.
  3. Record any DTCs and freeze-frame data displayed for system diagnosis. If driveability problem exists and no codes are present, go to TROUBLE SHOOTING - NO CODES article for diagnosis by symptom.
  4. If any DTCs are present, perform appropriate DTC test. See appropriate 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.
  5. After repairs for DTC have been completed, DTC must be cleared from ECM memory. See CLEARING DIAGNOSTIC TROUBLE CODES . Road test vehicle to ensure all symptoms and/or complaints have been repaired.
