Gently lower the DCDC and battery coolant heater approximately 1 in (25 mm)
to access the bottom nut that secures the forward junction box to the
bulkhead. Loosen the nut (torque 6 Nm), then reinstall the DCDC and battery
heater onto the retaining studs.
Note: It is not necessary to remove the nut entirely because the bolt hole
is slotted.
Remove the screws (x4) that secure the HV cables to the RH side of the
forward junction box (torque 7 Nm). Remove the negative HV cable, then
remove the positive HV cable.
Remove the upper 2 nuts that secure the forward junction box to the studs
on the bulkhead (torque 6 Nm). Gently pull the forward junction box toward
the front of the vehicle to allow access to the screws that secure the LH HV
cables.
On the LH side of the forward junction box, remove the screw that secures
the top of each HV cable (torque 7 Nm). Do not remove the lower screws at
this time.
Rotate the forward junction box so that the lower LH HV screws can be
accessed once the vehicle is raised.
Raise the vehicle.
On the LH side of the forward junction box, release the screws that secure
the bottom of each HV cable (torque 7 Nm). Do not release the cables at this
time.
