WARNING:

When performing any repairs that involve contact with high voltage components or systems, the technician performing repairs on the vehicle must verify that the system remains powered down during high voltage repairs.

  • This must be done by removing the service disconnect.
  • The high voltage power down procedure must also be performed to ensure that the vehicle is properly powered down.
  • The technician must know the whereabouts of the service disconnect throughout the repair.
  • The technician must ensure that no one reconnects the service disconnect while service is being performed.
  • The technician must recheck that the service disconnect has not been reinstalled in cases where the vehicle was unattended.
