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. Provide corrections and feedback to ServiceDevelopment@teslamotors.com.

Retirer

  1. Open all the doors and lower all the windows.
  2. Place the vehicle into Service Mode. See Mode Entretien.
  3. Remove the ancillary bay cover. See Couvercle - baie auxiliaire (Ensemble structural) (retirer et remplacer).
  4. Retirez le sectionneur de batterie pyrotechnique. Voir Sectionneur de batterie pyrotechnique (Ensemble structural) (retirez et installez).
  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.

  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
    Remarque
    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. Mesurez la tension à travers les points de montage de déconnexion de la batterie pyrotechnique puis installez la déconnexion de la batterie pyrotechnique Voir Sectionneur de batterie pyrotechnique (Ensemble structural) (retirez et installez).
  9. Install the ancillary bay cover. See Couvercle - baie auxiliaire (Ensemble structural) (retirer et remplacer).
  10. Exit Service Mode. See Mode Entretien.
  11. Raise all the windows and close all the doors.
