3. If no error is found, insert a known good map DVD-ROM of the same type and perform self-diagno-

sis again. If same result is shown, the NAVI control unit is malfunctioning. If result is normal, the map
DVD-ROM is malfunctioning.

Refer to

GPS antenna system

1. Visually check for a broken wire in the GPS antenna coaxial cable.

2. Disconnect GPS antenna connector, and make sure approximately 5V is supplied from the NAVI

control unit. If not, the NAVI control unit is malfunctioning. If 5V is supplied, replace the GPS
antenna. If the connection is still malfunction after the replacement of the GPS antenna, the NAVI
control unit is malfunctioning.

DIAGNOSIS BY HISTORY OF ERRORS

The “Self-diagnosis” results indicate whether an error occurred during the period from when the ignition switch
is turned to ON until “Self-diagnosis” is completed.
If an error occurred before the ignition switch was turned to ON and does not occur again until the “Self-diag-
nosis” is completed, the diagnosis result will be judged normal. Therefore, those errors in the past, which can-
not be found by the “Self-diagnosis”, must be found by diagnosing the “History of Errors”.
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 max 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 identified 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 find the items which show an increased number of occurrences, and diagnose the item.
