Remove
- Remove the pyrotechnic battery disconnect. See Pyro Disconnect - HV Battery (Remove and Replace).
- Disconnect ancillary bay harness connectors from negative pack contactor.
- Remove the HV joint insulators (x2) from the negative pack contactor.
-
Remove and discard the patch bolt that
attaches the negative pack contactor to the DC link busbar joint.
TIpUse of the following tool(s) is recommended:
-
Remove and discard the patch nut that
attaches negative pack contactor to the HV battery tall silicon terminal.
TIpUse of the following tool(s) is recommended:
-
Remove the nuts (x3) that attach the
negative pack contactor to the ancillary bay.
NoteUse insulated magnet to retrieve the nuts after removal. The number of nuts on newer vehicles may vary.TIpUse of the following tool(s) is recommended:
- Remove the guide pins (x2) to remove the negative pack contactor from the ancillary bay.
Install
- Position the negative pack contactor to the ancillary bay for installation, and then install the guide pins (x2).
-
Install the nuts (x3) that attach the
negative pack contactor to the ancillary bay, and mark after torque.9 Nm (6.6 lbs-ft)NoteUse insulated magnet as needed to position the nuts onto the studs. The number of nuts on newer vehicles may vary.TIpUse of the following tool(s) is recommended:
-
Install the patch bolt that attaches
the negative pack contactor to the DC link busbar joint, and mark after torque.
TIpUse of the following tool(s) is recommended:
-
Install the patch nut that attaches
negative pack contactor to the HV battery tall silicon terminal.
TIpUse of the following tool(s) is recommended:
-
Perform Hioki impedance test at the HV
joint of the negative pack contactor to the negative DC link busbar.
- If the resistance is greater than 0.060 mΩ (60 μΩ), there is too much resistance in the High Voltage joint. Remove the fastener, clean areas with isopropyl alcohol, install fastener back and test again.
- If the resistance is less than 0.020 mΩ (20 μΩ), reposition the probes and measure again.
-
Perform Hioki impedance test at the
negative pack contactor to module 1 rear terminal
NoteThe acceptable impedance is 110 μΩ or less.
- Install the HV joint insulators (x2) to the negative pack contactor.
- Connect the ancillary bay harness connectors (x2) to the negative pack contactor.
- Install the pyrotechnic battery disconnect. See Pyro Disconnect - HV Battery (Remove and Replace).
- Raise all windows and close all doors.
