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.
Error item
Some error items may be displayed simultaneously according to the cause. If some error items are displayed
simultaneously, the detection of the cause can be performed by the combination of display items

 Displays the communication status between AV control unit (mas-
ter unit) and each unit.
 The error counter displays “OK” if any malfunction was not
detected in the past and displays “0” if a malfunction is detected. It
increases by 1 if the condition is normal at the next ignition switch
ON cycle. The upper limit of the counter is 39.
 If it resets, the error counter is erased.

CONSULT-III Function (MULTI AV)INFOID:0000000003882712
CONSULT-III FUNCTIONS
CONSULT-III performs the following functions via the communication with the AV control unit.
AV COMMUNICATION
When “AV communication” of “CAN Diag Support Monitor” is selected, the following function will be performed.
SELF-DIAGNOSIS RESULTS
 In CONSULT-III self-diagnosis, self-diagnosis results and error history are displayed collectively.
 The timing is displayed as “0” if any of the error codes [U1000], [U1010], [U1300] and [U1310] is detected.
The counter increases by 1 if the condition is normal at the next ignition switch ON cycle.
