page
Gyro sensor disconnected
Communications malfunction between
NAVI control unit and internal gyro
Perform self-diagnosis to confirm
whether the NAVI control unit is mal-
functioning or not. If no failure is
detected, a momentary and/or tempo-
rary malfunction may have been caused
by strong electromagnetic wave interfer-
ence.
Connection problem of speed
sensor
Input malfunction of NAVI control unit
and speed sensor
Check vehicle speed sensor signal in
“Diagnosis for signals from the car”
mode. If the input signal is not detected
correctly, check harness for open or
short between combination meter and
NAVI control unit.
GPS disconnected
Communications malfunction between
NAVI control unit and GPS board
Perform self-diagnosis to confirm
whether the NAVI control unit is mal-
functioning or not. If no failure is
detected, a momentary and/or tempo-
rary malfunction may have been caused
by strong electromagnetic wave interfer-
ence.
GPS transmission cable malfunc-
tion
GPS input line connection error
GPS TCXO over
The transmission circuit of the GPS
board frequency synchronization oscilla-
tor (inside the NAVI control unit) is send-
ing an oscillation frequency that is
greater or less than the set value.
A location error occurs. Strong electro-
magnetic wave interference may have
occurred. The GPS antenna may be in a
very hot or very cold environment. This
is usually a temporary malfunction.
—
GPS TCXO under
GPS ROM malfunction
Internal malfunction of GPS board RAM
or ROM inside the NAVI control unit.
Perform self-diagnosis to confirm
whether the NAVI control unit is mal-
functioning or not. If no failure is
detected, a momentary and/or tempo-
rary malfunction may have been caused
by strong electromagnetic wave interfer-
ence.
GPS RAM malfunction
GPS RTC malfunction
Malfunction of GPS board clock IC
inside the NAVI control unit.
GPS antenna disconnected
—
Perform self-diagnosis to confirm GPS
antenna connection. If no failure is
detected, a momentary and/or tempo-
rary malfunction may have been caused
by a strong impact.
Low voltage of GPS
Power supply voltage for GPS board
inside the NAVI control unit is low.
1. Check power supply circuits for NAVI
control unit.
2. Perform self-diagnosis to confirm
GPS antenna connection.
3. If above diagnosis results are OK, a
momentary and/or temporary malfunc-
tion may have been caused by a strong
impact.
—
CD-ROM communication error
CD-ROM driver malfunction (inside the
NAVI control unit)
Perform self-diagnosis to confirm
whether the NAVI control unit is mal-
functioning or not. If no failure is
detected, a momentary and/or tempo-
rary malfunction may have been caused
by strong electromagnetic wave interfer-
ence.

CD-ROM reading error
It is confirmed that the appropriate CD-
ROM disc is positioned in the CD-ROM
loader. However, no data can be read.
Perform self-diagnosis to confirm
whether the inserted disc is malfunction-
ing or not.
Malfunctioning of error correction
for CD-ROM
Erroneous data is read from the CD-
ROM. The errors cannot be corrected.
CD-ROM focus error
CD-ROM data reading beam is out of
focus.
Rough road driving might create CD
skipping like music CD audio unit.
