Repair procedures

Inspection

1. Measure the pressure of high pressure line by measuring voltage output between terminal 1 and 2.




2. Inspect the voltage value whether it is sufficient to be regular value or not.





Voltage =0.00878835 * Pressure + 0.5 [PSIA]

3. If the measured voltage value is not within specification, replace the A/C pressure transducer.

Replacement

1. Disconnect the negative (-) battery terminal.
2. Recover the refrigerant with a recovery/charging station.

CAUTION:
- Do not use the same A/C recovery / charging station as conventional belt-driven compressors.
- Since the electric compressor uses high-voltage, you should use POE oil which have high volumetric resistivity.
- If the POE oil of the system gets mixed with PAG oil, then dielectric breakdown due to decreased volumetric Resistivity can occur and inoperative A/C compressor may result, A/C compressor may not work.

3. Disconnect the A/C pressure transducer connector (A).




4. Remove the A/C pressure transducer (B).

Tightening torque:
10 - 12 N.m (1.0 - 1.2 kgf.m, 7.4 - 8.8 lb-ft)





CAUTION:
Be careful not to bend the liquid & suction pipe.

5. Install in the reverse order of removal.
