Warning
Cybertruck electronics are powered by a 48V "mid voltage" or "MV" architecture that is designed to improve efficiency. Servicing MV components requires extra knowledge and care in order to avoid personal and/or vehicular harm. Read and understand MV precautions in Electrical Precautions and make sure any required MV-related training courses have been completed, as applicable.

Warning
Only technicians who have been trained in High Voltage Awareness and have completed all required certification courses (if applicable) are permitted to perform this procedure. Proper personal protective equipment (PPE) and insulating HV gloves with a minimum rating of class 0 (1000V) must be worn at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness Care Points for additional glove and safety information.

    Note
    1x plug, Line must be disconnected from pyro fuse access cover
  4. Install enclosure leak test adapter onto open thermal vent.
  5. Connect enclosure leak tester onto adapter.
  6. Close both valves on regulator.
  7. Connect regulator to air supply.
  8. Turn right side regulator valve to open position.
    Informational PurposesAn informational icon, calling your attention
    Note
    Turn valve knob to horizontal position.
  9. Set regulator to 0.3 psi.
  10. Open left side regulator valve to inject air into platter.
    Informational PurposesAn informational icon, calling your attention
    Note
    Close right side regulator valve when pressure reaches 0.3 psi and stabilizes, Allow platter to fill for 120 seconds.
  11. Wait 30 seconds for pressure to settle.
  12. Record value of starting pressure.
  13. Wait 30 seconds to test pressure.
  14. Record value of end pressure.
    Informational PurposesAn informational icon, calling your attention
    Note
    Subtract ending pressure from starting pressure, If difference is greater than 0.006 psi then inspect tools and retest, If difference is still greater than 0.006 psi then escalate to Service Engineering, If difference is 0.006 psi or less then proceed with current procedure.
  15. Disconnect air supply from regulator.
  16. Disconnect enclosure leak tester from adapter.
  17. Remove enclosure leak test adapter from open thermal vent.
  18. Remove plug from RH pressurized pack line.
  19. Connect RH pressurized pack line.
