2.�Important�Notes

By�separating�the�high-voltage�safety
connector,�a�bore�hole�becomes�free�through
both�parts.�The�loop�of�a�typical�U-lock�must�be
inserted�in�this�bore�hole.
The�U-lock�can�now�be�closed.�The�key�must
be�stored�in�a�safe�place�during�work�on�the
high-voltage�system�so�that�an�unauthorized
person�cannot�unlock�the�lock.
The�connector�can�no�longer�be�used�by
inserting�and�closing�the�U-lock�at�the�high-
voltage�safety�connector.�This�is�an�effective
way�of�ensuring�that�the�high-voltage�system�is
not�switched�on�again�without�the�knowledge
and�consent�of�the�Service�employee.
2.2.4.�Verifying�safe�isolation�from�the�supply
In�BMW�Service�the�de-energized�state�is�not�verified�using�a�measuring�device�or�via�the�diagnosis
system.�Instead,�the�high-voltage�components�measure�the�voltage�themselves�and�transmit�the
measuring�result�via�bus�signal�to�the�instrument�cluster.
The�instrument�cluster�does�not�generate�the�Check�Control�message�to�display�the�de-energized
state�unless�all�involved�high-voltage�components�consistently�signal�the�de-energized�state.�This
Check�Control�symbol�in�red�shows�a�crossed-out�flash�symbol.�The�text�message�"High-voltage
system�switched�off"�also�appears�in�the�instrument�cluster.
