The steering angle output value detected by the gyroscope can be
adjusted.
Speed Calibration
Usually the automatic distance correction function adjusts the mal-
function in distance caused by the tires wearing down or the tire
pressure change. If prompt adjus tment is necessary when the tire
chains are installed, et c., perform this procedure.
Error History
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 “Sel f 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 “Error His tory” for the past error that is not available
with self-diagnosis.
“Error History” displays the time and place of the most re cent 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 pos ition of the vehicle mark at the time when the error
occurred. If the vehicle mark has deviated from the co rrect position, then the place of the error occurrence
may not be located correctly.
When the ignition switch is turned ON if the error is det ected, the counter increases 1. Even if it is normal
when the ignition switch is turned ON t he next time, the counter does not decrease.
The upper limit of the counter is 50. 51 or more is displayed as 50. It can be reset to 0 by “Delete log” switch.

Diagnosis by Error History
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 maki ng a memo of the item and number of time (or delete
“Error History”). Check “Error History” again afte r the malfunction was reproduced, and then perform diagno-
sis focusing on the item of which number of time increased.
DVD-ROM error history may be restored because DV D-ROM cannot be temporarily read. (Driving on rough
road etc.) Then, erase the error history. (This is not a ma lfunction.) Perform service in “Action to take” if error
history are repeatedly indicated again.
