* Check LDC capacitor voltage in freeze frame data.

If Info Code1 is less than 2A and the voltage of LDC capacitor has formed over 92% of the voltage of battery pack, it is a problem on the motor inverter. It is necessary to inspect the inverter. If Info Code1 is greater than 2A, other high voltage parts operate abnormally, so it is necessary to inspect high voltage parts (LDC, A/C inverter, motor inverter, etc). However, in such case, pre-charging resistance may have been already damaged by fire resulting from malfunction of other parts, so check the resistance and if it is already damaged, it is necessary to replace it.
