  18. Remove the broken bolt head from the frunk harness ground terminal G625.
  19. Remove the broken stud of the ground point G625 from the LH crash rail.
    Informational PurposesAn informational icon, calling your attention
    Note
    Use locking pliers to remove the stud, turning it clockwise viewed from the front of the vehicle. Move the frunk harness front guide aside as needed.
  20. Use an M6 restoring tap to clean thread of the G625 ground point on the LH crash rail.
  21. Sand off the e-coat around the edges of the hole at the G625 ground point on the LH crash rail to ensure proper electrical connection.
    Informational PurposesAn informational icon, calling your attention
    Note
    Sand off a radius of 11 mm around the hole. Within 2 hours of removing the e-coat, prime all abraded areas. If the abraded areas are not primed within 2 hours, they must be abraded again to remove any oxidation. Do not use a conditioning disc that has been used on any material other than e-coat and aluminum. Cover brake line with a towel to prevent any damage.
  22. Sand off the e-coat around the edges of the hole at the G626 ground point on the RH crash rail to ensure proper electrical connection.

    CAUTION
    Take care not to damage the brake line: gently move the brake line aside with a plastic tool to access the bolt.
  29. Install the clip that attaches the frunk harness front guide to the LH side crash rail.
  30. Perform a Hioki resistance test at the frunk harness ground terminals G625 and G626 on the LH and RH side crash rails.
    Informational PurposesAn informational icon, calling your attention
    Note
    Measure the resistance between the exposed spot on the ground terminal and the exposed aluminum surface of LH and RH crash rail. If the resistance is 0.0001Ω or lower, then proceed with the rework. If resistance is more than 0.0001Ω, perform E-coat and oxidation cleaning on the contact points again.
