WARNING:

 

To prevent electric shock hazards, be sure to wear protective gear.

13. Disconnect high voltage harness connector.

WARNING:

•  

To prevent electric shock hazards, be sure to wear

protective gear.

• To prevent electric shock hazards, immediately wrap insu-

lating tape around disconnected high voltage connector

terminals.

• Follow the procedure below and disconnect high voltage harness connector.

14. Disconnect low voltage harness connector.

WARNING:

 

To prevent electric shock hazards, be sure to wear

protective gear.

15. Remove bolts (A) from electric compressor (1).

WARNING:

 

To prevent electric shock hazards, be sure to wear

16. Remove electric compressor (1) from the vehicle.

WARNING:

 

To prevent electric shock hazards, be sure to wear

protective gear.

17. Remove bolts (A), and then remove compressor bracket (1).

WARNING:

 

To prevent electric shock hazards, be sure to wear

protective gear.

INSTALLATION

Note the following items, and then install in the reverse order of removal.

WARNING:

 

To prevent electric shock hazards, be sure to wear protective gear.

CAUTION:

• Be sure to reinstall high voltage harness clips in their original positions. If a clip is damaged, replace

it with a new clip before installing.

• Before installing the new compressor, adjust the compressor oil level. Refer to 

HA-88, "Lubricant

Adjusting Procedure for Compressor Replacement"

.

• To prevent degradation in insulation performance, use special electric compressor oil as the com-

pressor oil.

• In order to prevent conventional PAG oil from becoming mixed in, never reuse recovered compres-

sor oil and instead always use new oil. The use of oil including the conventional PAG oil may

degrade the performance of insulation.

• To prevent performance degradation, never use a fluorescent agent in order to detect refrigerant

leakage. Also be careful that a fluorescent agent never enter the oil.

• To prevent leakage of refrigerant, replace the O-ring with a new one. Apply a coat of compressor oil

to the O-ring prior to installation.

• Perform a check for refrigerant leakage when charging with refrigerant. Refer to 

HA-84, "Check

Refrigerant Leakage"

.

• Set the vehicle to READY and operate the air-conditioner for at least 1 minute with the vehicle parked

to perform a break-in.

ELECTRIC COMPRESSOR

• If the compressor stay was replaced, first check that there is no

dust or dirt on the surface of the compressor stay, then apply the

new high voltage warning label at position (1), with the direction

indicated by the arrow facing up.

• Follow the procedure below and connect the high voltage harness connector.

• After all parts are installed, be sure to check the equipotential. Refer to 

HA-100, "Inspection"

.

Inspection

INFOID:0000000010122171

EQUIPOTENTIAL TEST

After installing the electric compressor, measure the resistance below.

• Between electric compressor (aluminum part) and body (ground bolt).

• Between electric compressor (aluminum part) and DC/DC-J/B (aluminum part).

WARNING:

 

To prevent electric shock hazards, be sure to wear protective gear.

If the result deviates from the standard value, check for paint, oil, dirt, or other substance adhering to the bolts

or conductive mounting parts. If such substances are found, clean the surrounding area and remove foreign

substances.

DANGER:

Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of

electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are

handled incorrectly. Be sure to follow the correct work procedures when performing inspection and

maintenance.
