Pinpoint Test 1: No Global Positioning System (GPS) Antenna Signal




PINPOINT TEST 1: NO GLOBAL POSITIONING SYSTEM (GPS) ANTENNA SIGNAL

Normal Operation

The global positioning system (GPS) antenna (integral to the satellite radio antenna) provides information from the GPS satellite system to the audio control module (ACM). This information is used to calculate vehicle position and direction of travel.A splitter is used in the lower 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 can cause a navigation system concern without affecting the satellite radio.

- DTC B119F:01 (GPS Antenna: General Electrical Failure) - sets when any failure is detected in the GPS antenna circuit.
- DTC B119F:13 (GPS Antenna: Circuit Open) - sets when an open is detected in the GPS antenna circuit.

Possible Causes
- Satellite radio antenna cable
- ACM
