投诉

Vehicle will not start.

The fault only occurs with the initial start-up after an ignition off/on (start/stop not affected).

The message "Stop. See operator's manual" is displayed in red in the instrument cluster.


原因

Fault code "B183349" is stored and current in 48 V battery G1/3.

The 48 V battery G1/3 has the software release 19/46 000 (software item number 000 902 12 60).


Due to an internal fault in the 48 V battery, the MOSFETs (internal switches) might not close when starting up.

If the MOSFETs do not close, the power supply for the vehicle would only be provided by the 12 V on-board electrical system battery.


补救

For the moment, please replace the 48 V battery G1/3.
