2-5 High-Voltage Safety System
The
high-voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high-voltage electricity. • A high-voltage fuse provides short circuit protection inside the high-voltage battery.
• The high-voltage safety system is insulated from the metal chassis.
• Positive and negative high-voltage power cables are connected to the high-voltage battery and arecontrolled by normally open system main relays (SMR1 and SMR2) . When the vehicle is shut off,
the relays stop electrical flow from leaving the high-voltage battery. However, it can take
approximately ten (10) minutes for the high-voltage capacitor to fully discharge. • The high-voltage system and high-voltage capacitor may remain powered for up to
approximately
10 minutes after the vehicle is shut off. Appropriate Personal Protective
Equipment (PPE) must always be worn when touching or working on high-voltage
components to avoid risk of electrical shock and severe personal injury or death.
• The high-voltage battery retains high-voltage at all times. Appropriate PPE must
always
be worn when touching or working on high-voltage components to avoid risk
of electrical shock and severe personal injury or death.
• A ground fault monitor continuously monitors for high-voltage leakage to the metal chassis while the vehicle is running. If a malfunction is detected, the HPCM (hybrid powertrain control module) will
illuminate the hybrid system warning lamp in the instrument cluster.
•

The high-voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow
in a front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) . HPCM

Alternate Procedure 1 (Remove Fuses)
NO
TE:
Before removing any fuses, if necessary, lower the windows, adjust the steering column,
adjust the seats, unlock the doors, etc. Once fuses are removed, power controls will not
operate.
1. Pull release handle (1) and pull up release lever (2) to open the hood.
2. Release clips (A) and remove fuse box cover (1) . : Vehicle front
3.

Remove IGCT RLY fuse (F/L V IGCT RLY 50A) .
4. If you cannot identify the correct fuse, remove all the fuses. To avoid unintended reinstallation and risk of
electrical
shock and severe personal injury or death, the
rescuer should carry the fuse or fuses on his/her person
and cover the fuse box with insulated tape. 1 2
