2004 and newer Toyota and Lexus Hybrid models are equipped with High-Voltage Three-Phase Alternating Current Air Conditioning Compressors,
which have specific safety and service requirements.
Electrically-driven A/C Systems safety precautions system operation component replacement service instructions and unique system features and
requirements are published in model-specific Repair Manuals that can be accessed through the Toyota Technical Information System (TIS).
Collision Repair Professionals should be aware of the following system characteristics:
^
Orange colored High-Voltage wiring is connected to electrically-driven A/C compressors (see photo).
^
Electrically-driven A/C compressors have no drive belt.
^
Electrically-driven A/C compressors require special ND-11 lubricating oil.
^
Underhood A/C system decal specifies use of ND-11 oil (see decal/label).
^
Use ONLY ND-11 lubricating oil because of its electrical insulating characteristics.
^
Avoid oil cross-contamination during evacuation and refrigerant charging by using hoses designated for ND-11.
^
Cross-contamination and the use of incorrect lubricating oil can set Diagnostic Trouble Codes (DTC) and cause damage to the electrically-driven
compressor.
