B1A89 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 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?
- 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?
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.

Frequently Asked Questions about B1A89 Code
1. What does the OBDII code B1A89 mean?
B1A89 indicates an issue with the satellite antenna, often related to its signal reception or connection to the vehicle's communication system.
2. What are the common symptoms of a B1A89 code?
Symptoms may include loss of satellite radio reception, poor signal strength, or an inability to access satellite-based services.
3. What causes the B1A89 code to be triggered?
The code can be caused by a damaged satellite antenna, loose or corroded antenna connections, or a malfunction in the radio or telematics control module.
4. How do I diagnose a B1A89 code?
Start by inspecting the satellite antenna for physical damage, checking the wiring and connections for corrosion or looseness, and using a diagnostic scanner to verify the issue.
5. Can a B1A89 code affect other systems in the vehicle?
Typically, no. This code is usually isolated to the satellite communication system and does not impact other vehicle functions.
6. How do I fix the B1A89 code?
Repair or replace the satellite antenna if damaged, clean and secure all connections, and, if necessary, update or replace the telematics control module.
7. Can environmental factors cause the B1A89 code?
Yes, factors like heavy rain, snow, or physical obstructions (e.g., roof racks) can temporarily block the satellite signal and trigger the code.
8. Is it safe to drive with a B1A89 code?
Yes, it is safe to drive, as the issue does not impact driving performance, but you may lose access to satellite services.
9. How much does it cost to fix a B1A89 code?
The repair cost can range from $100 to $400, depending on whether the antenna or wiring needs repair or replacement.
10. Can I clear the B1A89 code without repairs?
You can clear the code with an OBDII scanner, but if the underlying issue isn’t resolved, the code will likely return.
