以下为英文原文

Complaint 243: Red 12V battery message, white HV warning message, warning message in the IC and if applicable for vehicles with BMS30EB02 yellow HV drive system 465: Red 12V battery message, white HV warning message, warning message in the IC If the initial warning messages are ignored in the same ignition cycle, additional warning messages, e.g. red HV warning message and yellow HV drive system warning message may be shown. The DC/DC converter has stored a combination of the following two fault code groups: 1. P0C3B00, P0E9700, P0E5400, P0C4000. 2. P1D0B00, P1CA000, U011500. In some cases, not all DTCs from one of these groups are triggered. 243: As a consequence, on vehicles with BMS30EB02, the DTC for the auxiliary assembly fuse P0E2F00 can be set. This triggers the yellow HV drive system warning message. In the ignition cycle in which the red 12 V fault message is displayed, the DC/DC converter does not support the 12 V on-board electrical system. This means the 12 V battery may be discharged in the event of longer use. Cause In individual ignition cycles, this may result in faulty wake-up behavior of the DC/DC converter. The DCDC DTCs and warning messages may appear with a time delay. When accessing the vehicle, the white (243/465) HV warning message is displayed. When the HV system is switched on (charging, 12V supports, precon, ignition on), the yellow HV drive system warning message is displayed on the 243 with BMS30EB02 (see below for details). When the vehicle is started/PT-ready (displayed in the IC), the red 12V battery warning message is displayed for 243 and 465. - This warning message indicates that the DC/DC was not properly initialized in the current cycle and the 12V on-board electrical system is not being supplied. Since the BMS on 243 uses the HV voltage value to check the auxiliary assembly fuse, the auxiliary assembly DTC can (with BMS30EB02) be stored as a consequence and the second (yellow) HV drive system warning message can be displayed in the IC. Remedy 243 EB330 (BMS30EB02): Update the DC/DC converter software to version A0019024327 + Erase fault memory. 465: Update the DC/DC converter software to version A0019024327 + Erase fault memory. !!! Important note: Problems relating to this topic must be invoiced on the damage code for the DC/DC converter 54720. !!
