The Diagnostic Trouble Code (DTC) is output if there is insulation trouble with the high-voltage circuits in the air conditioning system. Insulation trouble with the electric inverter compressor or A/C inverter assy may be the cause. Any oil other than ND-OIL 11 may have entered the refrigeration cycle.
The motor-driven with high-voltage is built into the electric compressor and is cooled directly with refrigerant. Compressor oil (ND-OIL 11) with high insulation performance is used because leakage of electrical power may occur if regular compressor oil (ND-OIL 8) is used.
