- Component
- Equipment
- Summary
- Service Action: Replace EME B+ Cable. The Electric Machine Electronics (EME) has a connection for the B+ cable which leads to the 12V battery. This B+ cable transfers energy from the DC/DC converter to the 12V network. This cable may corrode over time and, in extreme cases, could break. In the event of a cable break, output from the DC/DC converter would be interrupted. This interruption would cause the 12V battery to discharge. Subsequently the customer would be notified via a check control message that the 12V battery is discharging, and the vehicle may not restart after being switched off.
