Removal
- Position the vehicle in preparation for raising it, but keep the
vehicle at ground level at this time.
- Perform the vehicle electrical isolation procedure (refer
to procedure).
- Remove the high voltage junction box (HVJB) cover (refer to
procedure).
Warning: Perform all of the voltage checks listed in the
procedure. If any voltage reading is more than 10V, the high voltage
contactors are not fully opened. Due to the risk of electrocution,
contact Service Engineering before performing any further work.
- Remove the nuts (x2) that secure the B+ and B- HV cables to the
HVJB (torque 9 Nm).
Note: It is not necessary to replace the
fastener(s) after it is removed. The threaded area
has a reusable dry sealant, which looks similar to
adhesive patch material.
- Remove the bolt that secures the HV fuse ground strap to the
body (torque 5.5 Nm).
- Release the edge clips (x2) that secure the HV harness to the
body of the vehicle.

- Remove the mid aero shield (refer to procedure).
- Remove and discard the screws (x4) that secure the B+ and B- HV
cables to the rear drive unit (torque 7 Nm).
- Install protective caps over both HV cables to protect the
terminals and seals.
- Release the cable ties (x2) that secure the HV cables to the
body of the vehicle.
