B1A89 Mercury Code - Satellite Antenna
Quick Answer
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. Common causes include Faulty Satellite Antenna, Satellite Antenna harness is open or shorted, Satellite Antenna circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B1A89 Mercury Description
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 any fault is detected in the satellite radio antenna circuit. This DTC can be either continuous or on-demand and applies to late build vehicles without navigation, and all vehicles with navigation or when an open is detected in the satellite antenna circuit. This DTC can be either continuous or on-demand and applies to late build vehicles without navigation and all vehicles with navigation.
What are the Possible Causes of the DTC B1A89 Mercury?
- Faulty Satellite Antenna
- Satellite Antenna harness is open or shorted
- Satellite Antenna circuit poor electrical connection
- Faulty Satellite Digital Audio Receiver System (SDARS) module (early build vehicles without navigation)
- Faulty Audio Control Module (ACM) (late build vehicles without navigation and all vehicles with navigation)
How to Fix the DTC B1A89 Mercury?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
