B2204 Code - GPS Antenna Connection Open Or Short
Quick Answer
The primary source of vehicle location for the navigation system is the Audio Control Module (ACM) receiving the position signal through the Global Positioning System (GPS) Antenna. Common causes include Faulty Global Positioning System (GPS) Antenna, Global Positioning System Antenna harness is open or shorted, Global Positioning System 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 B2204 Description
In addition, the ACM receives the wheel pulse signal from the Instrument Cluster (IC) (which gateways the signal from the Anti-Lock Brake System (ABS) module). This secondary signal is used to calculate vehicle position when the GPS signal is lost. It also supports the adaptive learning function of the ACM, whereby the ACM can compensate for long-term differences between the GPS signal location, and the actual distance traveled by the vehicle. The Diagnostic Trouble Code (DTC) will set when an open, short to ground, or short to voltage is detected in the GPS antenna circuit.
What are the Possible Causes of the DTC B2204?
- Faulty Global Positioning System (GPS) Antenna
- Global Positioning System Antenna harness is open or shorted
- Global Positioning System Antenna circuit poor electrical connection
