Charging Process

When this screen appears, follow the Repair Manual 
instructions for connecting the EV (HV) bonding cable 
(and low voltage cable, if applicable) to the vehicle.

When this screen appears, connect the low 
voltage cable (green HV (EV) bonding cable) 
to the GRX-5100.

Low voltage cable “R” is used 

for most Toyota hybrid models.

Low Voltage Cable

In the Repair Manual, the instructions for connecting cables 
between the vehicle and the THS charger refer to connecting  
an EV bonding cable (green wire) and also connecting a low 
voltage cable. 

When using the GRX-5100 on Toyota hybrid vehicles, however, 
the low voltage cable and the green HV (EV) bonding cable are 
one and the same – cable “R”.

Because 2001-2009 Prius models continue to use an green HV 
(EV) bonding cable AND a low voltage cable, the instructions on  
the GRX-5100 control panel refer to connecting the green HV (EV) 
bonding cable first, then connecting the low voltage cable next.

The bonding cable is essentially a ground wire used for 
detecting electrical leakage. The Repair Manual refers to it as 
the “EV bonding cable,” whereas the GRX-5100 screen refers 
to it as the “HV bonding cable.” They are the same cable.
