rectly (not up side down.)

2. Perform “CHECK THE MAP CD-

ROM VERSION” in EL-539 to
confirm whether correct CD-ROM
is inserted or not.

3. Check the disk surface. Are there

any scratches, abrasions or pits
on the surface?

4. Replace the CD-ROM.
5. Replace display & NAVI control

unit.

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-531

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-538

GPS disconnected

Communications malfunction between
display & NAVI control unit and GPS
board

EL-531

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 ROM malfunction

Internal malfunction of GPS board RAM
or ROM inside the display & NAVI con-
trol unit.

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 display & NAVI control unit is
low.

1. Check power supply circuits for dis-
play & NAVI control unit.
