Symptom |
Possible Cause |
Action |
Lost satellite reception |
- Vehicle not in clear view of satellites
- GPS antenna circuit: short circuit to ground, short circuit to
power, high resistance
- GPS antenna failure
- Navigation module failure
- Antenna is disconnected
|
:
|
Time taken to lock on to satellites can be several minutes after
ignition status is switched to 'ON' | It is
possible for the GPS antenna to lose satellite reception in hilly or
tree-lined areas, built-up areas, in multi-storey car parks, tunnels or
during heavy rain or thunderstorms. Check for DTCs indicating an antenna
or navigation module fault. |
Touch screen display (TSD) displays a high temperature
message and shuts down |
- MOST fibre optic transceiver (FOT) over-temperature
- FOT temperature greater than 85°C
|
Check MOST FOT temperature in TSD diagnostics, vehicle
signals. Once the temperature is reduced the system will resume normal
operation. If the system does not resume normal operation, check for DTCs
indicating an information and entertainment system fault. |
Touch screen display (TSD) displays a low temperature
message and shuts down |
- TSD too cold
- TSD temperature less than -25°C
|
Check MOST FOT temperature in TSD diagnostics, vehicle
signals. Once the temperature is increased the system will resume normal
operation. If the system does not resume normal operation, check for DTCs
indicating an information and entertainment system fault. |
