DESCRIPTION
 Trouble diagnosis function of navigation system has a Self Diagnosis mode by automatic operation and a
Confirmation/Adjustment mode by manual operation.
 Self Diagnosis mode checks for connec tions between the units constituting this system, analyzes each indi-
vidual unit at the same time, and displays the results on the display.
 Confirmation/Adjustment mode displays trouble diagnos is that require an operation and a judgment by a
human (auto-decision cannot be performed by the system), confirmation of preset value, and an error his-
tory.

Self-Diagnosis Mode (DCU)
INFOID:0000000001328753
OPERATION PROCEDURE
1. Start the engine.
2. Turn the audio system OFF.
3. While pressing the “4” button, turn the volume control dial clock- wise or counterclockwise for 30 clicks or more. (When the self-
diagnosis mode is started, a short beep will be heard.)
 Shifting from current screen to previous screen is performed
by pressing “BACK” button.
Mode Description
Self Diagnosis (DCU)  Display control unit diagnosis
 Analyzes connection between the display control unit and each unit, and
operation of each unit.
Self Diagnosis (NAVI)  NAVI control unit diagnosis (DVD-ROM drive will not be diagnosed when
no DVD-ROM is in it.).
 Analyzes connection between the NAVI control unit and the GPS anten-
na.
Confirmation/
Adjustment Display Diagnosis
Color tone and shading of the display control unit-generated image can be
checked by the display of a color bar and a gray scale.
Vehicle Signals Diagnosis of signals that are input to display control unit can be performed
for Vehicle Speed, IGN, Reverse and Light.
Auto Climate Control Refer to AT C - 4 3 , "
Self-Diagnosis Function".
Navigation Display Diagnosis
Color tone and shading of the NAVI control unit-generated image can be
checked by the display of a color bar and a gray scale.
Vehicle Signals Diagnosis of signals that are input to NAVI control unit can be performed for
Vehicle speed, Lights, Ignition and Reverse.
Navigation Steering An-
gle
Adjustment
This mode is used to correct difference between actual turning angle of a
vehicle and turning angle of the vehicle mark on the display.
Speed
Calibration Under ordinary conditions, the navigation system distance measuring func-
tion will automatically compensate for minute decreases in wheel and tire
diameter caused by tire wear or low-pressure. Speed Calibration can im-
mediately restore system accuracy in cases such as when distance calibra-
tion is needed because of the use of tire chains.
Error History Malfunctions that occurred in the past are displayed, along with the number
of times each has occurred. Time and location when/where the errors oc-
curred are also displayed.
Delete Unit Connection Log Erase the connection history of unit and error history.
CAN DIAG SUPPOPT MONITOR The transmitting/recei ving of CAN communication can be monitored.
