Volvo has identified that the Vehicle Connectivity Module (VCM) backup battery may be depleted while the vehicle is plugged in and charging the high voltage battery. This could result in a ?Volvo On Call Service Required? message displayed in the Driver Information Module (DIM). This condition has no effect on the vehicle?s drivability or performance.
