High Voltage Safety

High Voltage Safety System


The high voltage safety system is intended to help keep vehicle occupants, technicians 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 so there is no possibility of electric
shock when touching the chassis.

• Positive and negative high voltage power cables are connected to the high voltage battery and are
controlled 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.



























DANGER:
•
The high voltage system may remain powered for up to 10 minutes after the vehicle is shut
off.
•
The high voltage battery retains high voltage at all times.

Alternative High Voltage System Shut Down Procedure
NOTE:
If the service disconnect procedure cannot be performed, the following alternative shut down procedure is
acceptable.
1. Locate the fuse/fusible link box (1) under the hood near
the driver side strut tower (2).

DANGER:
•
The high voltage system may remain powered for up to 10 minutes after the vehicle is disabled.
•
To prevent serious injury or death from electrical shock avoid touching, cutting, or breaching any
orange high voltage power cable or high voltage component while the system discharges.
WARNING:
• The SRS may remain powered for up to 3 minutes after the vehicle is disabled.
• To prevent serious injury or death from unintentional SRS deployment, avoid crushing, cutting, or
breaching the SRS components.
• If the disabling procedures cannot be performed completely, proceed with caution as there is no
assurance that the high voltage electrical system, SRS, or fuel pump are disabled.










2. Remove the fuse/fusible link box cover and remove the
IGCT 50 amp fusible link (1) from the fuse/fusible link
box (2). If the correct fuse cannot be recognized, pull all
the fuses in the fuse/fusible link box.
