SFI SYSTEM (w/ Secondary Air Injection System) DTC CHECK / CLEAR

Note

Intelligent tester only:

When the diagnosis system is changed from normal mode to check mode, or vice versa, all DTCs and freeze frame data recorded in normal mode will be erased. Before changing modes, always check and make a note of DTCs and freeze frame data.


  1. CHECK DTC


    1. A01BHY4E01

      DTCs which are stored in the ECM can be displayed with the intelligent tester and generic OBD scan tool.

      These scan tools can display pending DTCs and current DTCs.

      Some DTCs aren't stored if the ECM doesn't detect a malfunction during consecutive driving. However, the detected malfunction during once driving is stored as a pending DTC.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the ignition switch to ON and turn the tester on.

      3. Enter the following menus: Powertrain / Engine and ECT / DTC.

      4. Check and make a note of DTCs and freeze frame data.

      5. Refer to the DIAGNOSTIC TROUBLE CODE CHART to confirm the details of the DTCs Click here.

        Note

        When simulating a symptom with the scan tool to check the DTCs, use normal mode. For codes on DIAGNOSTIC TROUBLE CODE CHART which are subject to "2-trip detection logic", perform the following procedures.

    2. Turn the ignition switch off after the symptom is simulated once. Then repeat the simulation process again. When the problem has been simulated twice, the MIL illuminates and the DTCs are recorded in the ECM.

  2. CLEAR DTCS AND FREEZE FRAME DATA (using an intelligent tester)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON (do not start the engine) and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / DTC / Clear.

    4. Erase DTCs and freeze frame data by pressing YES on the tester.

    5. Turn the ignition switch off and then turn it on again, and check that no DTCs are displayed on the monitor.

      If any DTCs are displayed, repeat from step (c).

  3. CLEAR DTCS AND FREEZE FRAME DATA (without using an intelligent tester)


    1. Perform either of the following operations:


      1. Disconnect the battery negative (-) cable for more than 1 minutes.

      2. Remove the EFI fuse from the engine room relay block No. 1 and the ETCS fuse from the engine room relay block No. 2 for 1 minute or more.

        However, if you disconnect the battery terminal, perform the "INITIALIZE" procedure Click here.
