Repair Procedures: Replacement

WARNING: This page is about a different variant/trim than selected.
  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).
