DTC Check/Clear

  1. CHECK DTC 
    1. DTCs which are stored in the ECM can be displayed with a Techstream.

      These scan tools can display pending DTCs and current DTCs. Some DTC are not stored if the ECM does not detect a malfunction during consecutive driving. When a malfunction is detected in only one driving cycle, it is stored as a pending DTC.

      1. Connect the Techstream to the DLC3.
      2. Turn the ignition switch to ON.
      3. Turn the tester ON.
      4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
      5. Check the DTCs and freeze frame data and then write them down.
      6. Check the details of the DTCs (See DIAGNOSTIC TROUBLE CODE CHART  ).
  2. CLEAR DTC (using a Techstream)
