Complaint Vehicle will not start after DC charging Warning in the instrument cluster related to High-voltage on board electrical system The following fault codes related to stuck contactor can be found in the High Voltage Control units : PTCU - N127 (Powertrain control unit)
• P154900 - There is a warning due to overcurrent in the charging system of the high-voltage electric circuit.
• P154A00 - There is a warning due to a detected crash event at standstill.
• P154B00 - There is a warning due to a stuck contactor. DCB223 - N116/5 (Direct current charge connection unit)
• P0E8929 - The input current of the on-board DC charging connection unit is too high. There is an invalid signal.
• P2BC500 - The contact ''Positive terminal'' of the contactor in the on-board DC current charge-connection unit is jammed closed
• P2BCC00 - The contact ''Negative terminal'' of the contactor in the on-board DC current charge-connection unit is jammed closed. Cause
• Current ripple due to EVSE (Electric Vehicle Supply Equipment)
• Overcurrent or Overvoltage due to EVSE (Electric Vehicle Supply Equipment)
• DCB contactors did not open immediately due to welding time at the end of DC charging Remedy
• Check for a new software availability for DCCU (N116/5 - Direct Current Charge connection Unit). If a new software is available, update the software first.
• Reset contactor fault through special procedure without password. ( N116/5 >> Special Procedure >> Resetting of contactor fault.) Important Note :
• Do not replace component DCB (N116/5)
• If fault codes are not erasable, please raise a TIPS case and send it to HQ.
