After reconnecting the negative battery cable, AMS and ISG functions will not operate for about 4 hours until the system stabilizes.

If the negative (-) battery terminal has been disconnected from the battery during repair work for a vehicle equipped with ISG function, battery sensor recalibration procedure should be performed after the repair work. (Refer to Battery Sensor Recalibration Procedure)

For vehicles equipped with battery sensor, be careful not to damage the battery sensor while replacing or recharging the battery.

When replacing the battery, it should be of the same type, capacity and brand as the one originally installed to the vehicle. If a battery of a different type is installed, the battery sensor may recognize the battery as abnormal.

When installing the ground cable on the negative post of battery, tighten the clamp to the specified torque. An excessive tightening torque can damage the PCB internal circuit and the battery terminal.

When recharging the battery, ground the negative terminal of the booster battery to the vehicle body.
