page
Gyro sensor disconnected
Communications malfunction between
display & NAVI control unit and internal
gyro
Perform self-diagnosis to confirm
whether the display & NAVI control unit
is malfunctioning 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-417
Connection problem of speed
sensor
Input malfunction of display & NAVI con-
trol unit and speed sensor
Check vehicle speed sensor signal in
“DIAGNOSTIC SIGNALS FROM THE
CAR” mode. If the input signal is not
detected correctly, check harness for
open or short between combination
meter and display & NAVI control unit.
EL-424
GPS disconnected
Communications malfunction between
display & NAVI control unit and GPS
board
Perform self-diagnosis to confirm
whether the display & NAVI control unit
is malfunctioning 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-417
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 display & NAVI control
unit) is sending 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 display & NAVI con-
trol unit.
Perform self-diagnosis to confirm
whether the display & NAVI control unit
is malfunctioning 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-417
GPS RAM malfunction
GPS RTC malfunction
Malfunction of GPS board clock IC
inside the display & 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.
EL-425
Low voltage of GPS
Power supply voltage for GPS board
inside the display & NAVI control unit is
low.
1. Check power supply circuits for dis-
play & NAVI control unit.
EL-438
2. Perform self-diagnosis to confirm
GPS antenna connection.
EL-417
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
display & NAVI control unit)
Perform self-diagnosis to confirm
whether the display & NAVI control unit
is malfunctioning 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-417
