46 Volt System 

 
The GS450h is equipped with a 46 Volt AC electrical system that powers the 
Electric Power Steering (EPS) assist motor in the engine compartment.   
 

•

 

46 Volt electrical system wires are bundled in amber sheathing for 
identification. 
 

•

 

The 46 Volt electrical system does not contain a storage battery. It is 
powered by converting high voltage battery power. The wires are 
routed underneath the vehicle from the HV battery pack DC-DC 
converter. 
 

•

 

If the HV battery pack malfunctions, backup power is provided to 
the EPS motor by boosting the 12 Volt electrical system. 

 

 
NOTE:  
46 Volts has a higher arc potential than 12 Volts DC.
