AUTOMATIC TRANSAXLE SYSTEM CHECK MODE PROCEDURE

Tech Tips

Check mode has a higher sensitivity to malfunctions and can detect malfunction that normal mode cannot detect. Check mode can also detect all the malfunctions that normal mode can detect. In check mode, DTCs are detected with 1-trip detection logic.


  1. DTC CHECK (CHECK MODE)

    Tech Tips

    Intelligent tester only: Compared to the normal mode, the check mode is more sensitive for detecting malfunctions. Furthermore, the same diagnostic items which are detected in the normal mode can also be detected in the check mode.


    1. Procedure for Check Mode using Intelligent tester.


      1. Check the initial conditions.


        • Battery positive voltage 11 V or more

        • Throttle valve fully closed

        • Transaxle in the P or N position

        • A/C switch is off

      2. Turn the ignition switch off.

      3. Connect Intelligent tester to the DLC3.

        Turn the ignition switch on (IG) and turn the Intelligent tester main switch ON.

      5. Enter the following menus: Powertrain / Engine and ECT / Utility / Check Mode.

        Note

        All DTCs and freeze frame data recorded will be erased if: 1) Intelligent tester is used to change the ECM from normal mode to check mode or vice-versa; or 2) during check mode, the ignition switch is turned from the on (IG) to on (ACC) or turned OFF.

      6. Start the engine (the MIL goes off after the engine starts).

      7. Perform "MONITOR DRIVE PATTERN" for the ECT test Click here, or simulate the conditions of the malfunction described by the customer.

        Note

        Leave the ignition switch on (IG) until you have checked the DTCs, etc.

      8. After simulating malfunction conditions, use Intelligent tester diagnosis selector to check the DTCs and freeze frame data, etc.

      9. When you use Intelligent tester: Enter the following menus: Powertrain / Engine and ECT / DTC / Current (or Pending).

      10. After checking the DTC, inspect the applicable circuit.

      11. Click here to confirm the details of the DTCs.

  2. DTC CLEAR


    1. When using Intelligent tester: Clearing the DTCs.


      1. Connect Intelligent tester to the DLC3.

      2. Turn the ignition switch on (IG) and turn the Intelligent tester main switch ON.

      3. When you use Intelligent tester: Enter the following menus: Powertrain / Engine and ECT / DTC / Clear.

        Tech Tips

        When operating Intelligent tester to erase the codes, the DTCs and freeze frame data will be erased. (See the Intelligent tester instruction book for operating instructions.)

    2. When not using Intelligent tester: Clearing the DTCs.


      1. Disconnect the battery cable or remove the EFI and ETCS fuses from the engine room junction block for 60 seconds or more. However, if you disconnect the battery cable, perform do the "INITIALIZATION Click here" procedure.
