SFI SYSTEM VEHICLE CONTROL HISTORY


  1. CHECK VEHICLE CONTROL HISTORY (ENGINE CONTROL SYSTEM)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Utility / Vehicle Control History (RoB).


      Powertrain > Engine > Utility
      Tester Display
      Vehicle Control History (RoB)
      Tester Display Measurement Item Diagnostic Note
      Auxiliary Battery Voltage Low at Start History of low battery voltage at engine control system start -
      Auxiliary Battery Voltage Low at IG OFF History of low battery voltage when engine switch off -
      Auxiliary Battery Discharge at IG OFF History of battery becoming discharged when engine switch off -
      Auxiliary Battery Discharge at Running History of battery becoming discharged while vehicle being driven -
  2. CLEAR VEHICLE CONTROL HISTORY (ENGINE CONTROL SYSTEM)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Enter the following menus: Powertrain / Engine / Utility / Vehicle Control History (Clear).

      Note

      By performing this procedure, all stored Vehicle Control History items will be cleared.

  3. VEHICLE CONTROL HISTORY FREEZE FRAME DATA (ENGINE CONTROL SYSTEM)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Utility / Vehicle Control History.

    5. Select a vehicle control history item to access the applicable freeze frame data.

    6. Check the freeze frame Data recorded with the Vehicle Control History.

      GTS Display Description
      Total Distance Traveled Driving distance
      Total Distance Traveled - Unit Unit of driving distance
      Initial Engine Battery Minimum Voltage Minimum voltage at engine start
      Alternator Voltage - Non Active Test Requested voltage when the regulator forced operation is not executed
      Alternator Output Duty Ratio LIN terminal output (power generation rate)
      Auxiliary Battery Voltage

      Battery voltage

      (+B1, +B2 terminal)

      Auxiliary Battery Integrated Current Battery capacity taking into account battery deterioration.
      Smoothed Value of Auxiliary Battery Temperature Calculated battery fluid temperature by battery fluid temperature sensor
      Auxiliary Battery Charge Rate Battery charge percentage calculated by battery sensor
      Auxiliary Battery Charging Rate Accuracy Accuracy of battery charge percentage calculated by battery sensor
      Auxiliary Battery Charging Capacity Battery charging capacity calculated by battery sensor
      Charging Control Mode Status of charging control
      Average Vehicle Speed during Trip Average vehicle speed after engine starts during the current trip
      Auxiliary Battery Integrated Current during Trip Integrated current value detected by the battery state sensor during the current trip
      Auxiliary Battery Charging Integrated Current when Trip before Last Integrated current charged during the previous trip
      Auxiliary Battery Discharging Integrated Current when Trip before Last Integrated current discharged during the previous trip
      Auxiliary Battery Capacity after IG ON Battery capacity immediately after engine switch on (IG)
      Auxiliary Battery Capacity after IG OFF Battery capacity immediately after engine switch off
      Estimated Open Ended Auxiliary Battery Voltage when IG OFF Estimated battery release voltage calculated when engine switch is off by the battery sensor
      Auxiliary Battery Average Current during IG OFF Average current while parked (average value of current consumed from when the engine switch is off until lit is on (IG))
      IG OFF Time just before IG ON Parking duration (duration from when the engine switch is off until it is on (IG))
      Auxiliary Battery Average Current when Auxiliary Battery Voltage Low (during IG OFF) Average current when system judges that voltage is low while parked (average current value when the engine switch is off until the system judges the voltage is low while parked)
      IG OFF Time when Auxiliary Battery Voltage Low (during IG OFF) Parking duration when system judges that voltage is low while parked (duration from when the engine switch is off until the system judges the voltage is low while parked)
      Elapsed Time during Auxiliary Battery Voltage Low Duration that the voltage detected by the battery state sensor while the vehicle is in motion is below the threshold (example: 11 V)
      Average Engine Speed Average engine speed after engine starts during the current trip
  4. CHECK VEHICLE CONTROL HISTORY (SRS AIRBAG)

    Tech Tips

    A part of the control history can be confirmed using the vehicle control history.
