DCC moderately high voltage on VCB-side
â–¶ How to fix
• Reset DTC • Toggle ignition key to "key off" and await system reset then "key on" i.e. system wake up. • Read out DTC's again • If DTC remains active check voltage level from battery pack E83. The voltage should be withing the range of 500V to 750V. • If over voltage detected check DTC’s from battery pack.
What you'll see
No driver-visible symptom recorded.
System reaction
• Derating of output current from 100% to 0% between 750-900V.
