        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 GTS after charging the battery, and drive the vehicle until the stop and start control operates (approximately 5 to 40 minutes).

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

          Tip:

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