Perform Hioki impedance test at the negative HV joint of the DC link side fast charge
busbar.
注The resistance should be 55𝜇Ω or less.
- Install the LH Ancillary Bay terminal cover.
- Install the harness clips (x2) to the FC contactor cover.
- Connect the LV fast charge connector.

- Install the pyrotechnic battery disconnect. See 电池烟火断开装置 ((拆卸和更换)).
-
Position the Ancillary Bay cover to HV battery for installation.
注Ensure all accessible insulators are present.
-
Use IPA wipes to clean the HV
connector contact surface and the busbar HV connector contact surface of the residual
Penetrox.
注Allow 1 minute dry time for each surface. The new busbar comes with the penetrox applied to the HV connector. It is necessary to clean the HV connector during the re-use of the busbar.
- Apply 2 drops of Penetrox A-13 about 5mm in diameter to either side of the hole on both leads on the HV connector joints, and then spread the liquid evenly until the contact surface is fully covered.
-
Position the busbar kit connector and
lower it onto the HV header.
注Shift the rear end of the busbar assembly upward to help ease installation. If excessive force is required to seat the busbar, they may have been bent. Inspect for damage and replace if necessary.

Perform Hioki resistance test at each
HV joint from the HV busbar lead to the bolt head.
注The acceptable resistance is between 0.050 mΩ (50 μΩ) and 0.195 mΩ (195 μΩ).
- If the resistance is greater than 0.195 mΩ (195 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 lower than 0.050 mΩ (50 μΩ), reposition the probes and measure again.
- If the resistance is repeatedly between 0.00 mΩ and 0.050 mΩ (50 μΩ), Hioki test passed, proceed to the next step.
