Warning
This procedure is a DRAFT. Although it has been validated, Warnings and Cautions might be missing. Follow safety requirements and use extreme caution when working on or near High Voltage systems and components.
Equipment:
  • 1018331-00-B (ADHESIVE,CURE IN PLACE,SILICONE,CRTRDG)

Remove

  1. Remove the HV battery and the Power Conversion System. See Power Conversion System (Remove and Replace)
  2. Remove the nuts (x2) that attach the A/C compressor fuse to the mounting studs.
  3. Use the fuse puller to remove the electrical harness terminal from the mounting stud and move aside.
  4. Use the HV insulated pick together with the fuse puller to carefully move the A/C compressor fuse out from under the electrical harness wires, and out of the front bay of the HV battery.

Install

  1. Perform a zero adjust of the Hioki resistance meter in preparation to measure resistances later in this procedure. See .
  2. Use the fuse puller to carefully install the A/C compressor fuse onto the mounting studs.
  3. Use the fuse puller to install the electrical harness terminal onto the mounting stud.
  4. Install the nuts (x2) that attach the A/C compressor fuse to the mounting studs.
    2.5 Nm (1.8 lbs-ft)
  5. Use the Hioki resistance meter to measure the resistance at the HV joint of the A/C compressor fuse and the positive DC busbar.

    CAUTION
    Do not short the side of the probe tip to the edge of the fuse lug.
    Informational PurposesAn informational icon, calling your attention
    Note
    The resistance must be less than 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.
