â–¶ How to fix
Check the vehicle HV DC-bus voltage for voltages above operating limits. Check for over voltage DTCs in other VCB components also.
What you'll see
No driver-visible symptom recorded.
System reaction
System will enter error mode and switch OFF
Diagnostic depth
Detection
Input voltage voltage sensor measures a overvoltage above 900V for 3 seconds or more.
Possible cause
Overvoltage in the DC bus
