Warning:
Only technicians who have been trained in High Voltage Awareness 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
at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech
Note TN-15-92-003, "High Voltage Awareness Care Points" for additional safety
information.
Remove
- Remove the pyrotechnic battery disconnect from the penthouse. See
Pyrotechnic Battery Disconnect (Remove and Replace).

- Raise the high voltage controller, release the clips that attach the
fuse access insulator to the RH penthouse bus cover, and remove the
insulator.

- Remove and discard the nuts that attach the A/C compressor fuse to the
RH penthouse bus and remove the fuse.

Fuse - A/C Compressor - HV Battery- Install
Install

- Install the A/C compressor fuse to the RH penthouse bus, and then
install new nuts to attach the fuse to the bus.
Torque 2.5 Nm
Generic Measurement - Actual busbars and fasteners might appear
different
- Use the Hioki resistance meter to measure the resistance at the HV joint
between the penthouse bus and the LH side of the A/C compressor fuse body .
Note: The maximum acceptable resistance is 0.105 mΩ (105 μΩ). If
the resistance is above this value, escalate a Toolbox session, as appropriate.

- Use the Hioki resistance meter to measure the resistance at the HV joint
between the RH side of the A/C compressor fuse and the respective ring
terminal plating.
Note: The maximum acceptable resistance is 0.145 mΩ (145 μΩ). If
the resistance is above this value, escalate a Toolbox session, as appropriate.

- Install the fuse access insulator on the RH penthouse bus cover, fasten
the clips that attach the insulator to the cover, and lower the high voltage
controller.
- Install the pyrotechnic battery disconnect into the penthouse. See
Pyrotechnic Battery Disconnect (Remove and Replace).
