122-B7U4T-052017-10-15. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Customer Concern: Certain vehicle systems have unwanted, unpredictable behavior. Technical Concern: The symptoms are difficult to diagnose. There may be multiple symptoms intermittently affecting multiple systems. Though this is not an exhaustive list, some common failure modes are: ? Start/stop issues ? Power windows not fully returning to the parked position after automatic preopening ? PCM audio stopping during a start/stop cycle Ultimately, the technician determines that low 12-volt battery voltage is the underlying root cause of the unwanted behavior. The technician corrects the battery?s low voltage. Consequently, the unwanted behavior ends.
