4.PERFORM DIAGNOSIS BY SYMPTOM
Perform the relevant diagnosis referring to the diagnosis chart by symptom. Refer to AV-108, "
Symptom
Table".
>> GO TO 5
5.REPAIR OR REPLACE MALFUNCTIONING PARTS
Repair or replace the identified malfunctioning parts.
NOTE:
Erase the stored self-diagnosis results after repairing or replacing the relevant components if any DTC No. has
been indicated in the self-diagnosis results.
>> GO TO 6

DIAGNOSIS SYSTEM (NAVI CONTROL UNIT)
The device name of Bluetooth can be confirmed and changed.
The device name can be changed by sixteen digits within A to Z
(small character can be used) and - (hyphen).
Delete Unit Connection Log
Deletes any unit connection records and error records from the NAVI
control unit memory. (Clear the records of the unit that has been
removed.)
Feature Restriction Setting
Operations of navigation system that are performed while driving
can be restricted by using this function.
CAUTION:
Once operational restrictions are imposed, they can not be can-
celled even when the software is updated or the language-
switching program is loaded.
CONSULT - III Function (MULTI AV)INFOID:0000000001728644
CONSULT-III functions
CONSULT-III performs the following functions via the communication with the NAVI control unit.
Self-diagnosis results
In CONSULT-III self-diagnosis, self-diagnosis results and error history are displayed collectively.
The current malfunction indicates “CRNT”. The past malfunction indicates “PAST”.
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.

COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000001728646
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 line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
