| Vian kuvaus | On affected vehicles, the screw connection of the ground terminal might not be torqued to specification due to a defect of the automatic screwdriver. The target torque of 21 Nm at the left ground screw might not have been achieved. A faulty screw connection can lead to an increased contact resistance at the screw connection. Potential damage to the PCU48 control unit due to voltage surges (display of CCM “Stop carefully. Energy supply.”) and potential loss of traction if the customer disregards CCMs. Potentially no longer possible to start the vehicle when the 48V battery is discharged. A local thermal event cannot be excluded. On affected vehicles the screw connection will be checked and reworked, if necessary. Damaged components will be replaced, if detected during the check. |
