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.

CONSULT-II FUNCTIONS
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II BASIC OPERATION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Select “MULTI AV” on “SELECT SYSTEM” screen. If “MULTI
AV” is not indicated, check the following items.
lNAVI contorol unit power supply and ground circuit.
lCONSULT-II data link connector (DLC) circuit
Refer toGI-50, "
CONSULT-II Data Link Connector (DLC) Cir-
cuit".
2. Select diagnosis item on “SELECT DIAG MODE” screen.
SELF-DIAG RESULTS
The self-diagnosis is started and self-diagnostic results are dis-
played by touching “START” after selecting “SELF-DIAG RESULTS”.
lIn CONSULT-II self-diagnosis, self-diagnostic results and error
history are displayed collectively.
lThe current malfunction indicates “CRNT”. The past malfunction
indicates “PAST”.
lIf DTC [U1000], [U1300] are detected, “0” is displayed at TIME.
If it is normal the next time ignition switch is ON, add 1 to the
TIME.
