12.2.�Starting�and�shutting�down�the�high-voltage�system
The�master�control�unit�for�the�control�of�the�high-voltage�system�is�the�electrical�machine�electronics.
12.2.1.�Starting
The�sequence�for�starting�the�high-voltage�system�is�always�the�same�irrespective�of�which�of�the
following�events�was�the�trigger:
• Terminal�15�is�switched�on�or�driving�readiness�is�established
• Charging�the�high-voltage�battery�should�start
• "Preparation"�of�the�vehicle�for�the�journey�(climate�control�of�the�high-voltage�battery�or�the
passenger�compartment).
The�individual�steps�for�starting�the�high-voltage�system�are:
1 EME�control�unit�requests�starting�via�bus�signal�at�the�PT-CAN�and�PT-CAN2
2 The�high-voltage�electrical�system�is�checked�using�self-diagnosis�functions
