Koledzy
Któregoś dnia mój fabryczny GPS nagle przestał pokazywać rzeczywiste położenie autka na mapie. Podłączyłem VCDS i sprawdziłem błędy. Rzeczywiście był jeden:
00862 - Antenna for GPS Navigation (R50/R52)
011 - Open Circuit - Intermittent
Freeze Frame:
Fault Status: 00101011
Fault Priority: 5
Fault Frequency: 4
Reset counter: 54
Mileage: 215237 km
Time Indication: 0
Date: 2012.06.21
Time: 12:35:24
Wykasowałem ten błąd, ale GPS dalej nie działa (błąd już się nie pojawia). Pomiary VCDS-em w sterowniku nawigacji wskazują, że antena nie widzi satelitów, ale status anteny jest OK. Doradźcie co może być przyczyną usterki?
13.90 V Voltage (Terminal 30)
0x0107 Dynamic Address (MOST-Databus)
0.00 Optical Transm. Power Reduction
33.0°C Send Diode Temperature
0x00FF Electrical Coding
1 Diagnostic Wire
Acq. Sattelites Received Satellites
0.0 Number of Received Satellites
GPS Antenna GPS-Antenna
OK GPS-Antenna Status
A może antena jest "zawieszona" i trzeba ją jakoś zresetować? Tylko jak?

Wymieniłem antenę GPS i jest OK. Zwracam uwagę, że po wymianie anteny na sprawną trzeba odczekać parę minut, na ekranie pojawią się prawidłowe dane dotyczące wysokości n.p.m., ale na mapie będzie nadal błędna pozycja auta. Wówczas trzeba przejechać paredziesiąt metrów, żeby navi zaktualizowała położenie.
pozdrawiam

Podłączyłem druga antenę GPS, ale w dalszym ciągu nawigacja nie pokazuje rzeczywistego położenia auta.
Czy macie jakiś schemat elektryczny od anteny w kierunku czytnika NAVI?
Zastanawiam się czy sygnał GPS nie idzie przypadkiem do wzmacniacza antenowego, który może być uszkodzony. Nie bardzo wiem co można dalej sprawdzać, bo komputer nie pokazuje błędów.

Sprawdź w blokach pomiarowych będziesz miał obraz co się dzieje.
