Method of diagnosis for malfunctioning system
+When system does not start, indicate malfunction connection between units by outbreak sound from sys-
tem.
Diagnosis procedure.
1. Turn ignition switch ON. Make sure whether or not route guide start sound which is output from NAVI con- trol unit indicate 10 seconds after.
2. Push and hold ªMAPº and ªDAY/NIGHTº switches simultaneously for 5 seconds or more. Make sure whether or not 2 times of beep sound or route guide start sound indicate.
3. According to the former two steps, select an proper diagnosis No. in the diagnosis result quick reference table.
4. Find estimated malfunctioning system from the diagnosis No. table and perform check.

Speed calibration
+During normal driving, distance error caused by tire wear and
tire pressure change is automatically adjusted for by the auto-
matic distance correction function. This function, on the other
hand, is for immediate adjustment, in cases such as driving with
tire chain ®tted on tires.

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.
