Description
The Global Positioning System (GPS) antenna provides information from the GPS satellite system to the Audio Control Module (ACM). This information is used to calculate position and direction of travel. A splitter is used in the front satellite radio antenna cable to split the signals between the satellite radio and the GPS. It is possible that a concern in the GPS signal line after the splitter may cause a navigation system concern without affecting the satellite radio. The OBDII code sets when any failure is detected in the GPS antenna circuit.
