DIAGNOSIS SYSTEM
DIAGNOSIS SYSTEM
PFP:00000
Navigation System Diagnosis FunctionEKS00Q6H
lThere are 2 diagnosis functions (on board diagnosis and diagnosis using CONSULT-II), and it is neces-
sary to use them properly according to the condition. If the on board diagnosis starts, perform diagnosis
with on board diagnosis. If the on board diagnosis does not start (the cause being that the system is not
started, the switch operation is not activated, etc.), perform diagnosis using CONSULT-II.
lAt on board diagnosis, the NAVI control unit diagnosis function starts by switch operation and the NAVI
control unit performs the diagnosis for each unit of system.
lAt diagnosis using CONSULT-II, the NAVI control unit diagnosis function starts by the communication
between CONSULT-II and NAVI control unit, and the NAVI control unit performs the diagnosis for each
unit of system.
On Bord Self-Diagnosis FunctionEKS00Q6I
DESCRIPTION
lThe on board diagnosis function has a self-diagnosis mode for performing trouble diagnosis automatically
and a Confirmation/Adjustment mode for operating manually.
lSelf-diagnosis mode performs the diagnosis at NAVI control unit, connections between each unit that
composes the system, and connections between NAVI control unit and GPS antenna. It displays the
results on the display.
lConfirmation/Adjustment mode is used to monitor the vehicle signals requiring operation and judgement
by a technician (malfunctions that cannot be automatically judged by the system), the confirmation/adjust-
ment of setting value, the error history of system, and the communication condition of system.
DIAGNOSIS ITEM
Mode Description
Self Diagnosis
lNAVI control unit diagnosis (DVD-ROM drive will not be diagnosed when
no map DVD-ROM is in it.)
lThe connection diagnosis between NAVI control unit and GPS antenna
and the connection diagnosis between NAVI control unit and each unit
can be performed.
Confirma-
tion/Adjust-
mentDisplay DiagnosisThe tint can be confirmed by the color spectrum bar display. The shading
of color can be confirmed by the gradation bar display.
Vehicle SignalsDiagnosis of signals can be performed for vehicle speed, parking brake,
lights, ignition (ignition switch), and reverse.
Speaker Test The connection of a speaker can be confirmed by test tone.
NavigationSteering Angle
AdjustmentWhen there is a difference between the actual turning angle and the vehi-
cle mark turning angle, it can be adjusted.
Speed CalibrationWhen there is a difference between the current location mark and the
actual location, it can be adjusted.
Error HistoryThe system malfunction and its frequency that occurred in the past are dis-
played. When the malfunctioning item is selected, the time and place that
the selected malfunction last occurred are displayed.
Vehicle CAN Diagnosis The transmitting/receiving of CAN communication can be monitored.
AV COMM DiagnosisThe communication condition of each unit that composes the system can
be monitored.
Handsfree PhoneEach setting of hands-free volume adjustment, voice microphone test,
delete hands-free memory can be performed.
Bluetooth Passkey and device name can be confirmed/changed.
Delete Unit Commection Log The connection history and error history of unit can be deleted.

DIAGNOSIS SYSTEM
Self Diagnosis Mode
EKS00Q6J
1. Start the diagnosis function, and then select “Self Diagnosis”.
–Self-diagnosis screen is displayed. The system enters in the self-diagnosis mode.
–The bar graph visible on the center of screen indicates the
progress of self-diagnosis.
2. Diagnostic results are displayed when the self-diagnosis is com-
plete. Each unit name and connection lines between each unit
will be colored according to the diagnostic results, as follows.
* : Only control unit (NAVI control unit) is displayed in red.
NOTE:
lSwitch: AV switch
lControl unit: NAVI control unit
lAmplifier is built in Audio unit.
–If multiple malfunctions occur at the same time for a single unit, the screen switch colors are determined
according to the following order of priority: red > yellow > gray.
–When selecting the screen switch on self-diagnosis screen, the
comment of self-diagnosis results is displayed.

ERROR DETECTION RANGE OF SELF-DIAGNOSIS MODE
lSelf-diagnosis mode can perform the connection condition diagnosis of communication circuit between
NAVI control unit and each unit and the NAVI control unit diagnosis.
lSince the start condition of diagnosis function is switch operation, if the malfunction is detected in the
communication circuit between NAVI control unit and AV switch, on board diagnosis function cannot be
started.
DIAGNOSIS RESULTS
Check the applicable display at the DTC quick reference table, and then repair the malfunctioning parts.

ERROR HISTORY
The diagnostic results of “Self-diagnosis” determine if any malfunction occurred between selecting “Self-diag-
nosis” and displaying “Self-diagnostic Results”. However if a malfunction occurred before selecting “Self-diag-
nosis”, and did not occur again before displaying “Self-diagnostic Results”, the diagnostic results are
determined to be normal. For this reason, past malfunctions that could not be determined at the time “Self-
diagnosis” was conducted must be diagnosed from the “Error History”. In “Error History”, time, date, and place
that the selected error last occurred are displayed. Be careful about the following.
lIf there is a malfunction with the GPS antenna circuit board in the NAVI control unit, the correct date and
time of occurrence may not be able to be displayed.
lThe place of occurrence is a current location mark display position marked when the error occurs. If this
mark is not in the correct position, the correct place of occurrence will not be displayed.
lThe frequency of occurrence is displayed by 2 types of the count down type and the count up type. Select
either type according to the error item.
Count Down Type
lWhen the error is detected, set the counter to 40. If the system is normal when turning the ignition switch
ON, it decreases by 1 on the counter.
lThe lower limit of the counter is 1. It can be reset to 0 by “Delete log” switch or CONSULT-II.
Count Up Type
lWhen the ignition switch is turned ON if the error is detected, the counter increases by 1. Even if it is nor-
mal when the ignition switch is turned ON next time, the counter is not decreased.
lThe upper limit of the counter is 50. 51 or more is displayed as 50. It can be reset to 0 by “Delete log”
switch or CONSULT-II.
