        Note:
        • All the stored DTCs and freeze frame data are cleared if the hybrid vehicle control ECU is changed from normal mode to check mode. Before changing modes, always check and note any DTCs and freeze frame data.

        • Changing from normal mode to check mode function is not available when the power switch is turned on (READY).

        • If a DTC is stored, check and note the DTC and freeze frame data following the GTS display, then change from normal mode to check mode.

  2. CHECK FREEZE FRAME DATA AND INFORMATION

    1. If a DTC is stored, select it in order to display its freeze frame data.

    2. Read the freeze frame data recorded when the DTC was stored.

      Note:

      A 3-digit information code (INF code) will be displayed as the value for one of the Information 1 to Information 5 lines.

  3. CHECK FOR DTCS (SYSTEMS EXCEPT HYBRID VEHICLE CONTROL ECU)

    Tip:

    The hybrid vehicle control ECU maintains communication with other ECUs, including the ECM, skid control ECU and power steering ECU. Therefore, if the hybrid vehicle control ECU outputs a warning, it is necessary to check and record the DTCs of all systems.

    1. If DTCs are stored, check the relevant systems.

      Tip:

      If DTCs for the CAN communication system are stored in addition to other DTCs, first troubleshoot and repair any malfunctions in the CAN communication system.
