      Cause and Action to be Taken

      Result Cause Action to be Taken
      A Integrated current value is limited for the stop and start control due to discharge or deterioration of the battery Check the battery condition and recharge or replace the battery
      B Integrated current value is limited for stop and start control due to battery temperature (too high/low) Leave the battery under room temperature conditions until its temperature becomes as specified. Then check the battery condition and recharge or replace the battery.
      • Initialize* the battery integrated current using the Techstream after charging the battery, and drive the vehicle until the stop and start control operates (approximately 5 to 40 minutes).

        *: Use the Techstream to perform Integrated Current Value Initialization.

        Refer to REGISTRATION [11/2016 - ]

        HINT: 

        If the Data List item "Integrated Current" is 0 Asec or higher, it is not necessary to perform initialization.

      • When the battery state sensor assembly current value is normal, recharge or replace the battery
      • When the electrical load is large, a large amount of electrical discharge occurs. As a result, the integrated current value (battery charge amount) tends to drop causing operation to be prohibited.

    NEXT 

    CHARGE OR REPLACE BATTERY AFTER CHECKING BATTERY STATE AND THEN INITIALIZE INTEGRATED CURRENT VALUE AND DRIVE VEHICLE UNTIL STOP AND START CONTROL OPERATES (APPROXIMATELY 5 TO 40 MINUTES) 

    Refer to Integrated Current Value Initialization.

    Refer to REGISTRATION [11/2016 - ]

  14. CHARGE OR REPLACE BATTERY AFTER CHECKING BATTERY STATE 
    1. Check the battery.

      Refer to ON-VEHICLE INSPECTION [11/2016 - ]

      HINT: 

      • Charge or replace the battery according to the check result.
      • When the cable is disconnected from the battery terminal or the charging control system is checked (ECM connector is disconnected), do not perform this procedure, as there is a high possibility that the system may enter refresh charge mode and operation may be prohibited.
    2. Check the starter inrush current reduction relay.

      Refer to Starter Inrush Current Reduction Relay Circuit [11/2016 - ] 

    3. Connect the Techstream to the DLC3.

      The headlights (Lo) are illuminated so that charging control is prohibited, which sets the voltage to a fixed value.

    9. Charge the battery for approximately 5 minutes after Battery Current drops 5 A or less.

      HINT: 

      The Data List item Battery Current decreases when the battery is charged. If the battery is charged for 5 minutes after Battery Current drops to 5 A or less, it can be determined that the battery is sufficiently charged.

  15. READ VALUE USING TECHSTREAM (HOOD COURTESY SWITCH) 

    HINT: 

    Check the engine hood courtesy switch (hood lock assembly).

    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Stop and Start / Data List / Hood Courtesy Switch.

      Powertrain > Stop and Start > Data List 

      Tester Display
      Hood Courtesy Switch
    5. According to the display on the Techstream, read the Data List.

      Result Proceed to
      When engine hood condition changes from open to closed, Data List switches from OFF to ON A
      When engine hood condition changes from open to closed, Data List remains OFF B

      HINT: 

      If the result is OK, the engine may have been started with the engine hood open to perform a jump start. Close the engine hood and start the engine again.

    Result:  2

    B 

    GO TO ENGINE HOOD COURTESY SWITCH CIRCUIT (OPERATION PROHIBITED AS ENGINE HOOD STATE DOES NOT CHANGE TO CLOSE). Refer to  Engine Hood Courtesy Switch Circuit [11/2016 - ]  

    Result:  1

    See step  16

  16. READ VALUE USING TECHSTREAM (STOP&START OPERATING PROHIBITION (JUMP START)) 
    1. Check that the engine hood is closed.
    2. Turn the ignition switch off and wait for 30 seconds or more.
    3. Turn the ignition switch to ON.
    4. Turn the Techstream on.
    5. Enter the following menus: Powertrain / Stop and Start / Data List / Stop&Start Operating Prohibition (Jump Start).

      Powertrain > Stop and Start > Data List 

      Tester Display
      Stop&Start Operating Prohibition (Jump Start)
    6. Check that the Data List item "Stop&Start Operating Prohibition (Jump Start)" displays "Permit".

      Powertrain > Stop and Start > Data List 

      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Stop&Start Operating Prohibition (Jump Start) Prohibition of stop and start control based on the jump start conditions Permit / Prohibit Prohibit: Engine started with the engine hood open and the ignition switch START When Prohibit is displayed, stop and start control will be prohibited until the ignition switch is turned off.

      HINT: 

      Stop and start control may be prohibited if the engine was started with the engine hood open.
