  1. DESCRIPTION


    1. Check mode has a higher sensitivity to malfunctions and can detect malfunctions 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.

  2. CHECK MODE PROCEDURE


    1. Make sure that the following conditions are met:


      1. Battery positive voltage 11 V or higher.

      2. Throttle valve fully closed.

      3. Shift lever in P or N.

      4. A/C off.

    2. Turn the ignition switch off.

      Change the ECM to check mode. Make sure the MIL flashes as shown in the illustration.

      Note

      All DTCs and freeze frame data will be cleared if: 1) the GTS 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 ON to ACC or off.

      Before entering check mode, make notes of the DTCs and freeze frame data.

    8. Start the engine. The MIL should turn off after the engine starts.

    9. Perform Monitor Drive Pattern for the ECT test, or simulate the conditions of the malfunction described by the customer.
