HV Harness - HVJB to Charge Port - 2nd Generation (Remove and Replace)
Correction Code 44500402
Warning
Only technicians who have been
trained in High Voltage Awareness and have completed all required certification
courses (if applicable) are permitted to perform this procedure. Proper personal
protective equipment (PPE) and insulating HV gloves with a minimum rating of
class 0 (1000V) must be worn any time a high voltage cable is handled. Refer to
Tech Note TN-15-92-003, "High Voltage Awareness Care Points"
for additional safety information.
Removal
- Perform the vehicle HV disablement procedure (refer to procedure).
- Remove the 2nd row seat cushion frame (refer to procedure).
- Remove the LH C-Pillar lower trim panel (refer to procedure).
- Remove the LH trunk trim (refer to procedure).
-
Remove the high voltage junction box (HVJB) cover (refer to procedure).
WarningPerform 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.
-
Starting from the front and working toward the rear of the vehicle, mark
the 4 HV cables that lead to the charge port from front to rear as L2, L3,
L1, and N.
-
Release the 4 bolts inside the HVJB that secure the HV cables that lead to the
charge port (torque 4.4 Nm).
NoteIt 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.
-
Release the nut that secures the grounding wire from the charge port
(torque 6 Nm).
-
Disconnect the proximity detection harness.
-
Remove the grounding bracket by releasing the nut that secures it to the body.
- Single phase (North America, Japan): torque 6 Nm
- 3 phase (Europe, APAC): torque 9 Nm
-
Remove the cover from the cable connector by using a trim tool or similar
non-conductive tool to bend the 3 tabs that secure the cover to the cable
connector.
NoteThe locations of the tabs are marked by arrows on the face of the cover.CAUTIONDo not lose or damage the magnet on the outboard side of the cable connector.
-
Remove the 3 bolts that secure the cable connector to the charge port in the
order shown. Remove the cable connector from the charge port.
- Single phase (North America, Japan): torque 4 Nm
- 3 phase (Europe, APAC): torque 5 Nm
CAUTIONEven though the HV harness is accessible, do not attempt to remove it at this time.NoteBefore performing the next step, note the locations of the clips that secure the HV harness to the 2nd row seat frame. During installation of the new HV harness, ensure that the harness is clipped to the seat frame in the same locations. -
Release the clips that secure the HV cables to the 2nd row seat
frame.
CAUTIONBefore performing the next step, examine the cable ties on the HV harness. Note that some of the cable ties are mounted to studs on the body.
-
Release the cable tie mounts that secure the harness to the studs on the
body.
-
Remove the harness assembly from the vehicle.
Installation
Installation procedure is the reverse of removal, except for the following:
- Ensure that the harness is clipped to the second row seat frame.
- When securing the cable connector to the charge port, tighten the bolts in the reverse order of removal.
- When securing the HVJB lid, first hand-tighten the HVIL bolt. Then, fully tighten the 5 nuts and 1 bolt in the reverse order of removal. Finally, fully tighten the HVIL bolt.
