Danger: Always perform the High Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.

Danger: This A/C system's high voltage A/C Compressor uses Polyolester (POE) refrigerant oil. Use of any refrigerant oil other than POE may result in compressor failure and/or loss of high voltage isolation which may result in serious danger or death. For applicable equipment please refer to TIS Newsletter/repair equipment information.

Preliminary Procedure

1. Disable hybrid high voltage system. Refer to High Voltage Disabling and High Voltage Enabling .
2. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging : High Voltage Electric Compressor .
3. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
4. Remove the air conditioning compressor and evaporator hose from air conditioning compressor front. Refer to Air Conditioning Compressor and Evaporator Hose Replacement .
5. Remove the exhaust manifold with catalytic converter. Refer to Exhaust Manifold with Catalytic Converter Replacement .
6. Remove the air conditioning compressor front hose. Refer to Air Conditioning Compressor Front Hose Replacement .
7. Disconnect the electrical connectors from the air conditioning and drive motor cooling compressor. Refer to High Voltage Connectors .

Procedure

1. Remove the air conditioning compressor and condenser hose from the air conditioning and drive motor cooling compressor. Refer to Air Conditioning Compressor and Condenser Hose Replacement .
2. A/C compressor oil balancing is not required. The service A/C compressor contains enough oil; however, add any oil that was removed during the A/C system recovery process. Refer to Refrigerant Recovery and Recharging : High Voltage Electric Compressor .
3. Reprogramme the A/C compressor. Refer to Air Conditioning Compressor Control Module Programming and Setup .
