HYBRID CONTROL SYSTEM VEHICLE CONTROL HISTORY


  1. VEHICLE CONTROL HISTORY (HYBRID CONTROL SYSTEM)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Utility / Vehicle Control History.

      GTS Display Measurement Item Note
      Charge / Discharge Control Value Limit by Battery Temperature

      History of HV battery charge/discharge being restricted

      If the temperature of the HV battery becomes approximately 44°C (111.2°F) or higher due to high ambient temperature, high cabin temperature, continuous driving under high load (such as mountain driving or frequent acceleration/deceleration), clogged hybrid battery intake duct, etc., the HV battery current will be restricted

      In this case the value of WIN/WOUT will decrease and the engine will stop and start less frequently.

      1. If this Vehicle Control History item is stored, perform the following inspections.


        • Check the Vehicle Control History freeze frame data.*

        • Check for clogs in the hybrid battery intake duct.

        • Inspect the HV battery cooling filter.

        • Check the intake port of the HV battery cooling system for blockage, such as luggage, etc.

      2. After performing the above inspections, check the temperature of the HV battery in the Data List.

        If the temperature of the HV battery is high (approximately 44°C (111.2°F) or higher), stop the vehicle, turn the air conditioning system on (Temperature: Lo, Blower speed: Max) and perform the Active Test "Control the Hybrid Battery Cooling Fan". Check that the temperature of the HV battery decreases.

      3. This Vehicle Control History item may be stored if the temperature of the HV battery became high due to certain conditions, such as if the ambient temperature was high, cabin temperature was high or the vehicle was driven continuously under high load (such as mountain driving or frequent acceleration/deceleration).

        Explain to the customer that this is not a malfunction.

      *: Check the following freeze frame data recorded with the Vehicle Control History.

      GTS Display Description Diagnostic Note
      Hybrid Battery Maximum Temperature Highest measured temperature of the HV battery Excessively high HV battery temperature: approximately 44°C (111.2°F) or higher.
      Hybrid Battery Cooling Fan Intake Air Temperature Battery cooling blower assembly intake air temperature If this value is high (approximately 38°C (100.4°F) or higher), due to high ambient temperature or high cabin temperature, the temperature of the HV battery may become high.
