NAVIGATION
1.
The navigation screen will be shown, and items “Display Longi-
tude & Latitude”, “Speed Calibration”, “Angle Adjustment” and
“Initialize Location” will become selective.
2.
Select each switch on “NAVIGATION” screen to display the rele-
vant diagnosis screen.
GPS ROM
malfunction
GPS RAM
malfunction
Contents of ROM (or RAM) in GPS substrate are malfunctioning.
●
Location detection accuracy of the navigation
system will deteriorate, depending on the error
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 inter-
ference.
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-collecting the whole sat-
ellite information when it judged the data
stored in the receiver is correct.)
●
Correct time of error occurrence may not be
stored in the

●
Perform self-diagnosis.
●
When the NAVI control unit is judged normal by self-diagnosis,
the symptom may be intermittent, caused by strong radio inter-
ference.
GPS antenna
disconnected
Malfunctioning connection between GPS substrate in NAVI control
unit and GPS antenna.
●
Navigation location detection performance
has deteriorated.
(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 inter-
mittent, caused by impact or vibration.
Low voltage
of GPS
The power voltage supplied to the GPS circuit board has
decreased.
●
Navigation location detection performance
has deteriorated.
(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 inter-

Angle adjustment
●
Adjusts turning angle output detected by the gyroscope.
Speed Calibration
●
During normal driving, distance error caused by tire wear and
tire pressure change is automatically adjusted for by the auto-
matic distance correction function. This function, on the other
hand, is for immediate adjustment, in cases such as driving with
tire chain fitted on tires.
