    Tech Tips

    Check the idling stop rate.


    1. Enter the following menus: Powertrain / Stop and Start / Data List / Idling Stop Rate.

    2. Check the following items on the GTS display.


      Powertrain > Stop and Start > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Idling Stop Rate Rate of the idling stop time to the entire ignition switch ON time Min.: 0%, Max.: 100% - -

      39% or less B

      Tech Tips

      When the idling stop rate exceeds 40%, turn the ignition switch off and then start the engine again. If NG is still displayed for the Data List item "Oper Permission (Battery)", the battery may be discharged or deteriorated. Check the battery condition and recharge or replace the battery.

  18. READ VALUE USING GTS (INTEGRATED CURRENT)

    Tech Tips

    Judge the battery condition based on the integrated current value.


    1. Start the engine and allow it to idle.

    2. Enter the following menus: Powertrain / Stop and Start / Data List / Integrated Current.

    3. Check the following items on the GTS display.


      Powertrain > Stop and Start > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note

        • *2: for 1ND-TV, 1NR-FE

        • After recharging the battery, initialize the integrated current value* and drive the vehicle until stop and start control operation is permitted (approximately 15 to 40 minutes).

          *: Disconnect the cables from the battery, wait for 30 seconds or more and then reconnect the cables.

        • When the battery sensor current value is normal, recharge or replace the battery
