Kia Soul EV: Heat Pump / Refrigerant Direction Control Valve Repair procedures

Kia Soul EV (PS EV) 2015-2020 Service Manual / Heating,Ventilation, Air Conditioning / Heat Pump / Refrigerant Direction Control Valve Repair procedures

Inspection

1. Vcc

2. Ground

Check the voltage between terminals 6 and 7.

Using the tester, check the resistance between terminals 1 and 2.

Replacement

[3-WAY Solenoid Valve]

Recover the refrigerant with a recovery/ recycling/ charging station.

•	Do not use the same A/C recovery / charging station as conventional belt-driven compressors.

•	Since the electric compressor uses high-voltage, POE oil with high resistivity should be used.Since the electric compressor uses high-voltage, POE oil with high resistivity should be used.

•	If PAG oil mixes into the POE oil of the system, dielectric breakdown may occur due to decreased volumetric resistivity and the A/C compressor may not work.

2.	Disconnect the negative (-) battery terminal.

3.	Disconnect the 3-WAY solenoid valve connector (A).

4.	Remove the refrigerant line after loosening the mounting nuts (A).

5.	Remove the 3-WAY solenoid valve assembly (A) after loosening the mounting bolt and nut.

Install in the reverse order of removal.

•	Do not use the same A/C recovery / charging station as conventional belt-driven compressors.
