Warning IconA warning icon, calling your attention to a possibly risky situation
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 IconA warning icon, calling your attention to a possibly risky situation
Warning
DO NOT SKIP the steps to remove the tonneau slats. Work on or around the ancillary bay REQUIRES the removal of the tonneau slats. Failure to remove the tonneau slats while working on or around the ancillary bay will result in conditions that may cause personal injury.

    Note
    When using the Hioki tester, verify the meter has been properly adjusted and set prior to usage.
    Informational PurposesAn informational icon, calling your attention
    Note
    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), the hioki test passed, proceed to next step.
  11. Remove the leather over gloves and the HV insulating gloves.
  12. Install the bolt that attaches the busbar HV connector lid.
