2 Carry the removed service plug in your pocket to prevent other technicians from
reinstalling it while you are dismantling the vehicle.
3 Use the CAUTION: HIGH VOLTAGE. DO NOT TOUCH DURING
OPERATION sign to notify other technicians that a high-voltage system is being
dismantled (see the page 17).
4. If the service plug cannot be removed
due to damage to the rear portion of
the vehicle, remove the HEV fuse
(20A:Yellow) or power integration
(IGCT relay) instead.
5 After disconnecting or exposing a
high-voltage connector or terminal,
insulate it immediately using
insulation tape. Before touching a bare
high-voltage terminal, wear insulated
gloves.
6. Check the HV battery and nearby area
for leakage. If you find any liquid, it
could be the leakage of the strong alkaline electrolyte. Wear rubber gloves and
goggles and neutralize the liquid using the saturated boric acid solution or vinegar.
Then wipe up the liquid using waste rags etc.
a) If the electrolyte adheres to your skin, wash the skin immediately using the
saturated boric acid solution or a large amount of water. If the electrolyte
adheres to an article of clothing, take it off immediately.
b) If the electrolyte comes into contact with your eyes, call out loudly for help.
Do not rub your eyes but wash them with a dilute boric acid solution or a
large amount of water and seek medical care.
7 Remove the parts by the procedures which are similar to the Toyota vehicles with
exception of HV battery. As for the removal of HV battery, place refer to
