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
GI-34, "High Voltage Precautions"
CAUTION:
Never bring the vehicle into the READY status with the service plug removed unless otherwise
instructed in the Instruction. 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
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 heating and cooling unit assembly. Refer to
HA-57, "HEATING AND COOLING UNIT ASSEM-
BLY : Removal and Installation"
3. Remove PTC heater from the heating and cooling unit assembly.
INSTALLATION
Install in the reverse order of removal.
Standard
: 5 V or less
