TRACTION MOTOR

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.

WARNING:

• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-

ing inspection or maintenance of high voltage system harnesses and parts.

• The removed service plug must always be carried in a pocket of the responsible worker or placed in

the tool box during the procedure to prevent the plug from being connected by mistake.

• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses

before beginning work on the high voltage system.

• Never allow workers other than the responsible person to touch the vehicle containing high voltage

parts. To keep others from touching the high voltage parts, these parts must be covered with an insu-

lating sheet except when using them.

• Refer to 

TMS-5, "High Voltage Precautions"

.

CAUTION:

Never bring the vehicle into the READY status with the service plug removed unless otherwise

instructed in the Service Manual. A malfunction may occur if this is not observed.

REMOVAL

WARNING:

Disconnect the high voltage. Refer to 

GI-33, "How to Disconnect High Voltage"

.

1. Check voltage in high voltage circuit. (Check that condenser are discharged.)
a. Lift up the vehicle and remove the Li-ion battery under covers. Refer to 

EVB-181, "Exploded View"

.

b. Disconnect high voltage harness connector and PTC heater harness connector from front side of Li-ion

battery. Refer to 

EVB-181, "Removal and Installation"

.

c.

Measure voltage between high voltage harness connector terminals and PTC heater harness connector

terminals.

DANGER:

 

 Touching high voltage components without using the appropriate protective equipment will

cause electrocution.

CAUTION:

For voltage measurements, use a tester which can measure to 500 V or higher.

2. Remove front under cover. Refer to 

EXT-23, "FRONT UNDER COVER : Exploded View"

.

Standard

: 5 V or less

3. Remove drain bolt   of traction motor to drain coolant.

WARNING:

To prevent electric shock hazards, be sure to put on insulat-

ing protective gear before beginning work on the high volt-

age system.

4. Drain reduction gear oil. Refer to 

TM-13, "Draining and Refill-

ing"

.

5. Remove electric power train and reduction gear from vehicle

together as suspension member assembly. Refer to 

FSU-22, "Removal and Installation"

.

6. Remove PDM (Power Delivery Module). Refer to 

VC-112, "Removal and Installation"

.

7. Remove traction motor inverter. Refer to 

TMS-103, "Removal and Installation"

.

8. Remove joint bolt (

) of motor mounting rear bracket and motor

mounting rear.

WARNING:

To prevent electric shock hazards, be sure to put on insulat-

ing protective gear before beginning work on the high volt-

age system.

9. Remove joint bolt (

) of motor mounting LH bracket and motor

mounting LH.

WARNING:

To prevent electric shock hazards, be sure to put on insulat-

ing protective gear before beginning work on the high volt-

age system.

10. Remove joint bolt (

) of motor mounting RH bracket and motor

mounting RH.

WARNING:

To prevent electric shock hazards, be sure to put on insulat-

ing protective gear before beginning work on the high volt-

age system.

11. Hook the sling belt to each motor mounting bracket and prepare

to disconnect the traction motor and reduction gear from the

front suspension member assembly.

12. Hoist the traction motor and reduction gear and disconnect them from the front suspension member

assembly.

WARNING:

To prevent electric shock hazards, be sure to put on insulating protective gear before beginning

work on the high voltage system.

TRACTION MOTOR

CAUTION:

When hoisting the traction motor and reduction gear, insert a long bolt into the motor mounting

bracket to prevent the sling belt from slipping out. At that time, be sure to install a nut.

13. Remove support bearing bracket of drive shaft (right side). Refer to 

FAX-19, "RIGHT SIDE : Removal and

Installation"

.

WARNING:

To prevent electric shock hazards, be sure to put on insulating protective gear before beginning

work on the high voltage system.

14. Remove motor mounting LH bracket  .

WARNING:

To prevent electric shock hazards, be sure to put on insulat-

ing protective gear before beginning work on the high volt-

age system.

15. Remove motor mounting rear bracket  .

WARNING:

To prevent electric shock hazards, be sure to put on insulat-

ing protective gear before beginning work on the high volt-

age system.

16. Remove motor mounting RH bracket  .

WARNING:

To prevent electric shock hazards, be sure to put on insulat-

ing protective gear before beginning work on the high volt-

age system.

17. Remove joint bolts traction motor and reduction gear.

WARNING:

To prevent electric shock hazards, be sure to put on insulating protective gear before beginning
