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 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. See Pyrotechnic Battery Disconnect (Remove and Replace).
- Raise the high voltage controller, release the clips that attach the fuse access insulator to the RH ancillary bay bus cover, and remove the insulator.
- Remove and discard the nuts that attach the A/C compressor fuse to the RH ancillary bay bus and remove the fuse.
Install
- Perform a zero adjust of the Hioki resistance meter in preparation to measure resistances later in this procedure. See Resistance Meter (Zero Adjust).
-
Install the A/C compressor
fuse to the RH ancillary bay bus, and then install new nuts to attach the fuse
to the bus.
-
Use the Hioki resistance meter to measure the resistance at the HV joint between the ancillary bay bus and the LH side of the A/C compressor fuse body .
NoteThe maximum acceptable resistance is 0.105 mΩ (105 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
-
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.
NoteThe maximum acceptable resistance is 0.145 mΩ (145 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
- Install the fuse access insulator on the RH ancillary bay bus cover, fasten the clips that attach the insulator to the cover, and lower the high voltage controller.
- Measure the voltage across the pyrotechnic battery disconnect mount points, and then install the pyrotechnic battery disconnect. See Pyrotechnic Battery Disconnect (Remove and Replace).
