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 “Error History”.
The Error History 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 identified because several errors are
present, record the item, number and place (longitude/latitude) of error occurrence (or delete the Error His-
tory), then turn the ignition switch from OFF to ON to reproduce the malfunction. Check the Error History to
find the items which show an increased number of occurrences, and diagnose the item.

sively high or low temperatures.

GPS ROM 
malfunction
GPS RAM 
malfunction

Contents of ROM (or RAM) in GPS substrate are malfunctioning.

●

system will deteriorate, depending on the error 
area in the memory, because GPS cannot 
make correct positioning.
