Error itemPossible causes
Example of symptom
Action/symptom
GPS ROM
malfunction
GPS RAM
malfunction Contents of ROM (or RAM) in GPS substrate are mal-
functioning.
+
Location detection accuracy of the navigation system
will deteriorate, depending on the malfunctioning area
in the memory, because GPS cannot make correct
positioning. (Location correction using GPS is not per-
formed.)
+
Perform self-diagnosis.
+ When the NAVI control unit is judged normal by self-
diagnosis, the symptom may be intermittent, caused
by strong radio interference.
GPS RTC
malfunction Clock IC in GPS substrate is malfunctioning.
+
Correct time may not be displayed.
+ After the power is turned on, the system always takes
some time until GPS positioning becomes possible.
(The GPS receiver starts positioning without re-col-
lecting the whole satellite information when it judged
the data stored in the receiver is correct.)
+ Correct time of error occurrence may not be stored in
the ªHistory of Errorsº.
+
Perform self-diagnosis.
+ When the NAVI control unit is judged normal by self-
diagnosis, the symptom may be intermittent, caused
by strong radio interference.
GPS antenna
disconnected Malfunctioning connection between GPS substrate in
NAVI control unit and GPS antenna.
+Navigation location detection performance has dete-
riorated. (Location correction using GPS is not per-
formed.)
+ GPS receiving status remains gray.
+
Perform self-diagnosis.
+ When connection between NAVI control unit and
GPS antenna is judged normal by self-diagnosis, the
symptom may be intermittent, caused by impact or
vibration.
