B125C Code - Satellite Antenna Circuit
Quick Answer
The digital radio receiver, located inside the radio, receives digital radio information from the digital radio antenna located on the outside of the vehicle. Common causes include Faulty Radio Antenna Base (Cellular Phone, Navigation and Digital Radio Antenna), Radio Antenna Base harness is open or shorted, Radio Antenna Base circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
