Gyro sensor disconnectedCommunications malfunction between
NAVI control unit and internal gyroPerform 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.EL-401

ªDiagnosis for signals from the carº
mode. If the input signal is not detected
correctly, check harness for open or
short between combination meter and
NAVI control unit.EL-408
GPS disconnected
Communications malfunction between
NAVI control unit and GPS boardPerform 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.EL-401 GPS transmission cable malfunc-
tion
GPS input line connection error
GPS TCXO overThe 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.Ð
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.EL-401 GPS RAM malfunction
GPS RTC malfunctionMalfunction of GPS board clock IC
inside the NAVI control unit.
GPS antenna disconnected ÐPerform 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.EL-401
Low voltage of GPSPower supply voltage for GPS board
inside the NAVI control unit is low.1. Check power supply circuits for NAVI
control unit.EL-429
2. Perform self-diagnosis to confirm
GPS antenna connection.EL-401
3. If above diagnosis results are OK, a
momentary and/or temporary malfunc-
tion may have been caused by a strong
impact.Ð
CD-ROM communication errorCD-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

Loading mechanism malfunction ÐCheck that whether the disc can be
inserted and ejected correctly. If the
loading function does not operate
correctly, replace NAVI control unit.Ð
CD-ROM reading errorIt 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.EL-401
Malfunctioning of error correction
for CD-ROMErroneous data is read from the CD-
ROM. The errors cannot be corrected.
CD-ROM focus errorCD-ROM data reading beam is out of
focus.Rough road driving might create CD
skipping like music CD audio unit.Ð
