VEHICLE SIGNALS
A comparison check can be made of each actual vehicle signal
and the signals recognized by the system.
If vehicle speed is NG, refer to AV- 8 9 , "Vehicle Speed Signal Check" .
If light is NG, refer to AV- 9 0 , "Illumination Signal Check" .
If IGN is NG, refer to AV- 9 0 , "Ignition Signal Check" .
If reverse is NG, refer to AV- 9 1 , "Reverse Signal Check" .
HISTORY OF ERRORS
Diagnosis results of self-diagnosis depend on if any error occurred during the time after selecting “Self-Diag-
nosis” until self-diagnosis results is displayed.
Meanwhile, when an error occurs before selecting “Self-Diagnosis”, and if an error does not occur until self-
diagnosis results is displayed, a diagnosis result is judged as normal.
Consequently, a diagnosis needs to be performed with “History of Error” for the past error that is not available
with self-diagnosis.
“History of Error” 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 vehicle mark at the time when the error
occurred. If the vehicle mark has deviated from the correct position, then the place of the error occurrence
may be located correctly.

“History of Error” stores error occurrences up to 50, and errors after the 51st are displayed as the 50th.
Diagnosis by History of Errors
When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunction,
turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or delete
“History of Error”). Check “History of Error” again after the malfunction was reproduced, and then perform
diagnosis focusing on the item of which number of time increased.

sively high or low temperatures.
GPS ROM
malfunction
GPS RAM
malfunctionContents of ROM (or RAM) in GPS substrate are malfunctioning.
Location detection accuracy of the navigation
system will deteriorate, depending on the error
area in the memory, because GPS cannot
make correct positioning.

Correct time may not be displayed.
After the power is turned on, the system
always takes some time until GPS positioning
becomes possible. (The GPS receiver starts
positioning without re-collecting the whole sat-
ellite information when it judged the data
stored in the receiver is correct.)
