What Does the B1031 Mercury Code Mean?

Digital signals are received by the satellite radio antenna and sent to the Satellite Digital Audio Receiver System (SDARS) module, which then converts the signals and provides audio signals to the ACM.
Late Build Vehicles Without Navigation And All Vehicles With Navigation: Digital signals are received by the satellite radio antenna and sent directly to the ACM, as the satellite radio receiver is built into the ACM.
A short to ground in the satellite radio antenna typically has no effect on the antenna signal. However, an open in the antenna circuit results in no sound from the satellite radio system. A short to voltage in the antenna circuit can have varying effects on the system. The OBDII code sets when an open or high resistance is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand and applies to early build vehicles without navigation.
