Diagnosis DescriptionINFOID:0000000003765657
MULTIFUNCTION SWITCH AND PRESET SWITCH SELF-DIAGNOSIS FUNCTION
The ON/OFF operation (continuity) of each switch in the multifunction switch and preset switch can be
checked.
Self-diagnosis Mode
 Press the “BACK” switch and the “UP” switch of the 4-direction
switches within 10 seconds after turning the ignition switch from
OFF to ACC and hold them for 3 seconds or more. Then the
buzzer sounds, all indicators of the preset switch illuminate, and
the self-diagnosis mode starts.
 The continuity of each switch at the ON position can be checked
by pressing the switch. The buzzer sounds if the switch is normal.
NOTE:
The hazard switch and disk eject switch cannot be checked.
Finishing Self-diagnosis Mode
Self-diagnosis mode is canceled when turning the ignition switch OFF.
MULTI AV SYSTEM ON BOARD DIAGNOSIS FUNCTION
 The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit
performs a diagnosis for each unit in the system during the on board diagnosis.
 Perform a CONSULT-III diagnosis if the on board diagnosis does not start, e.g., the screen does not display
anything, the multifunction switch does not function, etc.
ON BOARD DIAGNOSIS
Description
 The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and
a confirmation/adjustment mode for operating manually.
 Self-diagnosis mode performs the AV control unit diagnosis and the connection diagnosis between each of
the units that make up the system, and it indicates the results to the display.
 The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and
set values, as well as to monitor the system error records and system communication status. The check,
modify or adjust actions generally require human intervention and judgment (the system cannot make judg-
ment automatically).

2. Diagnosis results are displayed after the self-diagnosis is com-
pleted. The unit names and the connection lines are color-coded
according to the diagnostic results.
NOTE:
 Only the control unit (AV control unit) is displayed in red.
 Replace AV control unit if “Self-Diagnosis did not run because of a control unit malfunction” is indicated.
The symptom is AV control unit internal error. Refer to AV-378, "
Removal and Installation".
- If multiple errors occur at the same time for a single unit, the screen switch colors are determined accord-
ing to the following order of priority: red > yellow > gray.
- The comments of the self-diagnosis results can be viewed with a
component in the diagnosis result screen.
SELF-DIAGNOSIS RESULTS
 The self-diagnosis mode allows the technician to diagnose the connection in the communication line
between AV control unit and each unit and the internal operation of the AV control unit.
 Because the start condition of diagnosis function is a switch operation, the on board diagnosis function can-
not be started up if any malfunction is detected in the communication circuit between AV control unit and
multifunction switch.
 Check the applicable display in the following table, and then repair the malfunctioning parts.

Error History
The self-diagnosis results are judged depending on whether any error occurs from when “Self-diagnosis” is
selected until the self-diagnosis results are displayed.
However, the diagnosis results are judged normal if an error has occurred before the ignition switch is turned
ON and then no error has occurred until the self-diagnosis start. Check the “Error Record” to detect any error
that may have occurred before the self-diagnosis start because of this situation.
The error record displays the time and place of the most recent occurrence of that error. However, take note of
the following points.
 Place of the error occurrence is represented by the position of the current location mark at the time an error
occurred. If current location mark has deviated from the correct position, then the place of the error occur-
rence cannot be located correctly.
 The frequency of occurrence is displayed in a count up manner. The actual count up method differs depend-
ing on the error item.
Count up method A
 The counter resets to 0 if an error occurs when IGN switch is turned ON. The counter increases by 1 if the
condition is normal at a next IGN ON cycle.
 The counter upper limit is 39. Any counts exceeding 39 are ignored.“ The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT-III.
Count up method B
 The counter increases by 1 if an error occurs when IGN switch is ON. The counter will not decrease even if
the condition is normal at the next IGN ON cycle.
 The counter upper limit is 50. Any counts exceeding 50 are ignored. “ The counter can be reset (no error
record display) with the “Delete log” switch or CONSULT-III.Squawker : 3 kHz

COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003765661
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.
