3 When ªDVD-ROM is not recognized. Please check the disc.º is shown.
1. Eject map DVD-ROM and check if it is compatible with the system.
2. Check ejected DVD-ROM for dirt, damage, and warps.
3. If no error is found, insert a known good map DVD-ROM of the same type and perform self-
diagnosis again. If same result is shown, the NAVI control unit is malfunctioning. If result is
normal, the map DVD-ROM is malfunctioning. Ð
4 If ªError found in DVD-ROM or DVD-ROM driver in control unit. Please perform diagnosis in
accordance with service manualº is shown, performed same inspection as diagnosis No. 3. Ð
5 GPS antenna system
1. Visually check for a broken wire in the GPS antenna coaxial cable.
2. Disconnect the GPS antenna connector and make sure that approximately 5V is supplied
from NAVI control unit. If not, the NAVI control unit is inoperative. If the voltage is supplied,
replace the GPS antenna and perform self-diagnosis again. If the same result is shown, the
NAVI control unit is inoperative. Ð

DIAGNOSIS BY HISTORY OF ERRORS
The ªSelf-diagnosisº results indicate whether an error occurred during the period from when the ignition switch
is turned to ON until ªSelf-diagnosisº is completed.
If an error occurred before the ignition switch was turned to ON and does not occur again until the ªSelf-di-
agnosisº is completed, the diagnosis result will be judged normal. Therefore, those errors in the past, which
cannot be found by the ªSelf-diagnosisº, must be found by diagnosing the ªHistory of Errorsº.
The History of Errors displays the time and place of the most recent occurrence of that error. However, take
note of the following points.
+Correct time of the error occurrence may not be displayed when the GPS antenna substrate within the
NAVI control unit has malfunctioned.
+ Place of the error occurrence is represented by the position of the current location mark at the time when
the error occurred. If the current location mark has deviated from the correct position, then the place of
the error occurrence may be located correctly.
+ The maximum number of occurrences which can be stored is 50. For the 51st and later occurrences, the
displayed number remains 50.
When a reproducible malfunction occurred but its cause cannot be identi®ed because several errors are
present, record the item, number and place (longitude/latitude) of error occurrence (or delete the History of
Errors), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the History of Errors
to ®nd the items which show an increased number of occurrences, and diagnose the item.
