2) Wait at least 1 minute before proceeding to the next step. High voltage system shut down is
performed during this waiting time.
3) Disconnect the 12V battery negative terminal. This will disconnect the power supply to
the
SRS
airbag system and the EV ECU. Disconnect the 12V battery negative terminal by using
a 10mm wrench as follows:
①
Remove the cover of the 12V battery under the hood. Turn the plastic nut (A) counter
clockwise, and then remove the battery upper cover (B).
②
Disconnect the negative terminal from the 12V battery.
4) If necessary, cut the negative 12V battery cable, then wrap electrical tape to insulate the
cable ends.
5) Wait at least 5 minutes before proceeding to the next step. Working with the High voltage
circuit in the Main drive lithium-ion battery can be performed about 5 minutes after
disconnecting the 12V battery negative terminal.
6) Remove the Service Plug by following the procedure below.
①
Adjust the
front left side seat
to its rear most position and roll up the carpet under the seat.
Detach the service lid by removing two wing nuts.
If it is difficult to move the seat, remove it.
WARNING;
After disconnecting the 12V battery negative terminal, to avoid the risk of inadvertent air bag
deployment, wait at least
1 minute
. The SRS air bag system is designed to retain enough
voltage to deploy the air bag for a short time even after the 12V battery has been disconnected.
WARNING;
Always wear Personal Protective Equipment (PPE) when removing the Service Plug.
If the Service Plug is removed without following the procedure described in this section, a
short circuit can occur and melted metal debris may fly from the service plug terminal, resulting
in injury to
dismantlers
.
