DCC overvoltage on VCB-side
â–¶ How to fix
•If DTC remains active check voltage level from battery pack E83. The voltage should be withing the range of 500V to 722V. •If over voltage detected check DTC’s from battery pack.
What you'll see
No driver-visible symptom recorded.
System reaction
• VOR, 24V not charging. DCC will be disabled and enter error state and the 24-volt system will drain the 24-volt batteries. • Amber warning lamp "24V batteries not charged" and "Hybrid System Fault" is shown in ICL
Diagnostic depth
Detection
High DC Bus Voltage (SW detected) High DC Bus Voltage (HW detected)
Possible cause
•Hybrid battery has wrong voltage level •Too much generating power allowed
