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.

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 

VC-6, "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 high voltage. Refer to 

GI-33, "How to Disconnect High Voltage"

.

1. Check voltage in high voltage circuit. (Check that condenser are discharged.)

WARNING:

Be sure to put on insulating protective gear before beginning work on the high voltage sys-

tem.

a. Lift up the vehicle and remove the Li-ion battery under covers. Refer to 

EVB-181, "Exploded View"

.

b. Remove high voltage harness   from clamp  .

c.

Disconnect high voltage harness connector and high voltage harness for PTC heater from front side of Li-

ion battery. Refer to 

EVB-181, "Removal and Installation"

.

d. Measure voltage between high voltage harness connector terminals and high voltage harness connector

terminals for PTC heater.

DANGER:

 

 Touching high voltage components without using the appropriate protective equipment will

cause electrocution.
