拆卸

  1. Open all the doors and lower all the windows.
  2. Place the vehicle into Service Mode. See 维护模式.
  3. Remove the ancillary bay cover. See 盖板 - 高压电池仓（结构化电池组）（拆卸和更换）.
  4. 拆下烟火电池隔离开关。请参阅烟火电池断接开关（结构化电池组）（拆卸和安装）。
  5. Disconnect the HV battery positive contactor connectors (x2).
  6. Release the clip that attaches the negative harness to the tray.
  7. Remove and discard the bolts (x2) that attach the positive contactor to the busbars.
    5 Nm (3.7 lbs-ft) + 60 degrees
    提示： 推荐使用以下工具：
    • 13 毫米套筒
  8. Remove the bolts (x3) that attach the positive contactor to the assembly tray.
    6 Nm (4.4 lbs-ft)
    提示： 推荐使用以下工具：
    • 8 毫米套筒
  9. Remove the HV battery positive contactor from the ancillary bay.

安装

  1. Position the HV battery positive contactor into the ancillary bay.
  2. Install the bolts (x3) that attach the positive contactor to the assembly tray.
    6 Nm (4.4 lbs-ft)

    注
    Hand start bolts to verify the contactor is centered.
    提示： 推荐使用以下工具：
    • 8 毫米套筒
  3. Install new bolts (x2) that attach the positive contactor to the busbars.
    5 Nm (3.7 lbs-ft) + 60 degrees
    提示： 推荐使用以下工具：
    • 13 毫米套筒
  4. Use a Hioki resistance meter to measure the resistance at the HV joint between the newly-installed positive contactor and the positive DC link busbar.
    Informational PurposesAn informational icon, calling your attention
    注
    The acceptable resistance is between 0.004 mΩ (4 μΩ) and 0.050 mΩ (50 μΩ). If the resistance is greater than 0.050 mΩ (50 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 0.004 mΩ (4 μΩ), reposition the probes and measure again.
  5. Use a Hioki resistance meter to measure the resistance at the HV joint between the newly-installed positive contactor and the positive terminal flex busbar.

  6. Install the clip that attaches the negative harness to the tray.
  7. Connect the positive contactor connectors (x2).
  8. 测量烟火电池隔离开关安装点间的电压，然后安装烟火电池隔离开关。请参阅烟火电池断接开关（结构化电池组）（拆卸和安装）。
  9. Install the ancillary bay cover. See 盖板 - 高压电池仓（结构化电池组）（拆卸和更换）.
  10. Exit Service Mode. See 维护模式.
  11. Raise all the windows and close all the doors.
