СИСТЕМА ЗАПУСКА И ОСТАНОВА (для моделей с 3ZR-FAE) РЕЖИМЫ DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    Note

    In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the GTS to the DLC3.

    4. Start the engine.

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Stop and Start / Data List.

    7. According to the display on the GTS, read the Data List.

    • *: Regarding Battery Integrated Current

      In the stop and start system, the engine stop and start ECU switches the system control mode (stop and start control permitted/prohibited) based on the battery condition (charge/discharge condition) to protect the battery and to ensure stable engine restarting performance.

      The battery charge-discharge condition is determined from the integrated current value calculated from the battery state sensor assembly signal. The integrated current value is obtained by multiplying the current (Ampere) detected from the battery state sensor assembly by the time (seconds), and it is expressed in a unit A-sec.

      Tech Tips

      Example: Integrated current of -3110 A-sec corresponds to a load where current of 10 A flows out from the battery for 311 seconds.

      Using the Data List function of the GTS, the integrated current value can be read by checking the Data List item "Integrated Current". The item "Battery Integrated Current" shows the permission status of stop and start control (ON or OFF) and is judged from the "Integrated Current" value.

      Negative integrated current represents battery discharge, and positive represents battery charge. In other words, the "Integrated Current" value of the Data List item will decrease from the present value when the battery is discharged, and the value will increase when the battery is charged.

      The engine stop and start ECU determines the amount of power available based on the integrated current value, and it prohibits stop and start control if the value is below the threshold, because the battery might not be able to start the engine. The threshold varies according to the battery temperature.


    • Integrated Current Condition 1:

      When "Status of Battery Charge Control" is Charge Control Coordination Mode or Stop and Start Standalone Mode:

      A01QSV0E06

        Stop and Start System Operation (for Condition 1)

      • Phase A (previous trip integrated current storage):

        When the ignition switch is turned off, the integrated current value is recorded in the ECU memory. The value is carried over to the next trip.

      • Phase B (stop and start control permitted):

        Stop and start control is permitted to stop the engine until the integrated current reaches less than -14342 A-sec.

      • Phase C (charging):

        When the integrated current has dropped to less than -14342 A-sec, stop and start control is prohibited from stopping the engine until the current reaches -13478 A-sec.

      • Phase D (stop and start control permitted):

        Stop and start control is permitted to stop the engine until the integrated current reaches less than -14342 A-sec.


    • Integrated Current Condition 2:

      When "Status of Battery Charge Control" is Low Temperature Mode and "Battery Fluid Temperature" is between 3°C (37.4°F) and under 11°C (51.8°F):

      A01QSV0E07

        Stop and Start System Operation (for Condition 2)

      • Phase A (previous trip integrated current storage):

        When the ignition switch is turned off, the integrated current value is recorded in the ECU memory. The value is carried over to the next trip.

      • Phase B (stop and start control permitted):

        Stop and start control is permitted to stop the engine until the integrated current reaches less than -6912 A-sec.

      • Phase C (charging):

        When the integrated current has dropped to less than -6912 A-sec, stop and start control is prohibited from stopping the engine until the current reaches -6048 A-sec.

      • Phase D (stop and start control permitted):

        Stop and start control is permitted to stop the engine until the integrated current reaches less than -6912 A-sec.


    • Integrated Current Condition 3:

      When "Status of Battery Charge Control" is Low Temperature Mode and "Battery Fluid Temperature" is between -1°C (30.2°F) and under 3°C (37.4°F):

      A01QSV0E08

        Stop and Start System Operation (for Condition 3)

      • Phase A (previous trip integrated current storage):

        When the ignition switch is turned off, the integrated current value is recorded in the ECU memory. The value is carried over to the next trip.

      • Phase B (stop and start control permitted):

        Stop and start control is permitted to stop the engine until the integrated current reaches less than -4838 A-sec.

      • Phase C (charging):

        When the integrated current has dropped to less than -4838 A-sec, stop and start control is prohibited from stopping the engine until the current reaches -3974 A-sec.

      • Phase D (stop and start control permitted):

        Stop and start control is permitted to stop the engine until the integrated current reaches less than -4838 A-sec.


    • Integrated Current Condition 4:

      When "Status of Battery Charge Control" is Stop and Start Restriction Mode or Temperature High/Low Mode:

      A01QPDBE04

        Stop and Start System Operation (for Condition 4)

      • Phase A (previous trip integrated current storage):

        When the ignition switch is turned off, the integrated current value is recorded in the ECU memory. The value is carried over to the next trip.

      • Phase B (stop and start control permitted):

        Stop and start control is permitted to stop the engine until the integrated current reaches less than -864 A-sec.

      • Phase C (charging):

        When the integrated current has dropped to less than -864 A-sec, stop and start control is prohibited from stopping the engine until the current reaches 0 A-sec.

      • Phase D (stop and start control permitted):

        Stop and start control is permitted to stop the engine until the integrated current reaches less than -864 A-sec.

    Tech Tips


    • Performance (internal resistance) of lead-acid batteries used in typical vehicles changes according to the battery temperature. The internal resistance of the battery tends to be higher when the battery temperature is low. Thus, the stop and start system switches the threshold for determining the power charge according to the battery temperature when performing stop and start control.

    • If the battery is deteriorated, the internal resistance has also increased and the stop and start rate becomes lower. (The total of idling time while the vehicle is stopped increases.)

    • When troubleshooting, if the malfunction cannot be identified, the battery might be deteriorated.

  2. ACTIVE TEST

    Tech Tips

    Using the GTS to perform Active Tests allows relays, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Stop and Start / Active Test.

    5. Perform the Active Test by referring to the table below.

    Tech Tips

    Even if stop and start control is prohibited due to the condition of any of the systems listed above, performing the Active Tests allows stop and start control to be performed.
