Replacement
- Discharge refrigerant from refrigeration system.
- Replace faulty tube or hose. CAUTION: Cap the open fittings immediately to keep moisture or dirt out of the system.
- Tighten joint of bolt or nut to specified torque. CAUTION: Connections should not be torque tighter than the specified torque. Part tightened N.m kgf.m lb-ft Condenser - Discharge hose 3.9~5.9 0.4~0.6 2.9~4.3 Condenser - Liquid tube Compressor - Discharge hose 3.9~5.9 0.4~0.6 2.9~4.3 Compressor - Suction hose Expansion valve - Evaporator 7.8~11.7 0.8~1.2 5.7~8.6
- Evacuate air in refrigeration system and charge system with refrigerant. Specified amount 550 ± 25g (19.4 ± 0.88 oz.)
- Inspect for leakage of refrigerant. Using a gas leak detector, check for leakage of refrigerant.
- Inspect A/C operation.
Scheme 295
| Fault code | Fail description | Remedy |
|---|---|---|
| 60 | Compressor CAN signal fault | Check HV, LV connector connection. Check LV connector pin condition. Check vehicle inverter fuse condition. A/C ON then check compressor operation. If not operate, replace compressor. |
| 61 | Compressor operation state error receive | |
| 62 | Low voltage | Check HV connector connection. Check vehicle inverter fuse condition. Check voltage level of high voltage battery. A/C ON then check compressor operation. If not operate, replace compressor. |
| 63 | High voltage | Identify vehicle model on compressor Check voltage level of high voltage battery. A/C ON then check compressor operation. If not operate, replace compressor. |
| 64 | Overheat protection | Check heating object in engine room. Check A/C system for defects. After 20 minutes, IG ON and A/C ON then check compressor operation. If not operate, replace compressor. |
| 65 | Overloaded | Check cooling fan operation. Check AAF(Active Air Flap) for short circuit After 20 minutes, IG ON and A/C ON then check compressor operation. If not operate, replace compressor. |
| 66 | Over current protection | |
| 68 | Missed restart | |
| 71 | Failure of Over torque stall | |
| 67 | Abnormal (not receiving) | Check 12V battery fuse. Check LV connector connection. Check FATC CAN connection. If not operate, replace compressor. |
| 69 | Failure of thermistor open | Check thermistor condition and inspect. |
| 70 | Failure of thermistor short | |
| 72 | Failure of short circuit current | Replace compressor. Check vehicle inverter fuse (if necessary, replace). |
| 73 | Failure of driver voltage | |
| 74 | Failure of current measuring | |
