        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 integrated current drops. Check the battery condition and recharge or replace the battery
        B Integrated current value is limited for stop and start control due to battery charge control mode.
        C Integrated current value is limited for stop and start control due to battery temperature (too high/low) and battery charge control mode. Leave the battery under room temperature conditions until its temperature becomes as specified. Then check the battery condition and recharge or replace the battery.

        • After recharging the battery, using the GTS, initialize the integrated current item*.

          *: If the Data List item "Integrated Current" indicates 0 or more, initialization is not necessary.

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