High Voltage System Shutdown Sequence
The preferred sequence for High Voltage System shutdown is specified below. Crash severity,
location of deformation, vehicle orientation, safety of occupants and first responders, and other
variables may influence the ability to perform the High Voltage System shutdown in the following
sequence. When the vehicle has been severely damaged and the Lithium ion battery has been
deformed, broken, or appears to have been damaged in any way, appropriate Personal Protective
Equipment (PPE), such as high voltage gloves rated at least 1000V and a face protection mask,
must be used and the Lithium ion battery or high voltage components must not be touched.
Even if the collision is minor and there is no visible damage to the battery and high voltage
components, as a precaution the below sequence should be followed.
Perform the following steps:
1.
Turn vehicle off and remove key. The READY light should turn off.
2.
Disconnect or cut 12V battery cable in the trunk.
3.
Disconnect Main Service Disconnect (MSD) in the front middle of the battery pack under
the front of the vehicle.
4.
Disconnect Rear Service Disconnect (RSD) under rear seat inside vehicle.
5.
Disconnect main high voltage cable connector at Front Power Distribution Box (FPDB)
under the hood if MSD or RSD are not accessible. The FPDB is located under the hood.
