Diagnosis by Error History

When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunc-
tion, turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or
delete “Error History”). Check “Error History” again after the malfunction was reproduced, and then per-
form diagnosis focusing on the item of which number of time increased.

DVD-ROM error history may be restored because DVD-ROM cannot be temporarily read. (Driving on
rough road etc.) Then, erase the error history. (This is not a malfunction.) Perform service in “Action to
take” if error history are repeatedly indicated again.
Error item Possible cause Action to take
GPS Antenna ErrorGPS antenna connection malfunction
is detected1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, GO TO 3. If any
error is not found, delete the error his-
tory and end the diagnosis. (This is not
a malfunction.)
3. Check if GPS antenna feeder line is
snapped or pinched.
4. If the results from the above checkup
show no malfunction, replace GPS
antenna, and then restart self-diagno-
sis.
5. If self-diagnosis results still show any
malfunction, replace NAVI control unit.
FLASH-ROM Error Of Control Unit
NAVI control unit malfunction is
detected1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, replace NAVI con-
trol unit. Refer to AV- 9 8 , "
Removal and
Installation of NAVI Control Unit" . If any
error is not found, delete the error his-
tory and end the diagnosis. (This is not
a malfunction.) Connection Of Gyro

malfunction occur, intermittent malfunc-
tion caused by strong radio interference
may be detected.

DVD-ROM1. Check if the inserted DVD-ROM is
specified for this navigation system,
and the DVD-ROM is dirty, scratched or
warped.
2. If the results from the above checkup
show no malfunction, insert the same
DVD-ROM, and then restart self-diag-
nosis.
3. If self-diagnosis results still show any
malfunction, replace NAVI control unit. DVD-ROM Communication Error
