DIAGNOSIS SYSTEM (AV CONTROL UNIT)
AV Communication
When “AV communication” of “CAN Diag Support Monitor” is selected, the f\
ollowing function will be performed.
ECU IDENTIFICATION
The part number of AV control unit is displayed.
SELF DIAGNOSIS RESULT
 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 e rror 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.
Self-diagnosis Results Display Item
Data Monitor The diagnosis of vehicle signal that is input to the AV control unit can be performed.
Work Support Steering angle sensor can be adjusted.
Configuration Read and save the vehicle specification.
 Write the vehicle specification when replacing AV control unit.
Diagnosis mode Description
AV communication
AV&NAVI C/U
Displays the communication status from AV control unit to each unit as well as the error
counter.
AUDIO Displays the AV control unit communication status and the error counter.

FAIL-SAFE CONDITIONS
When the ambiance temperature is −20 °C ( −4 °F) or lower, or when it is 70 °C (158 °F) or higher
Display
The messages displayed on fail-safe conditions are as shown below:
DESCRIPTION OF CONTROLS
Ability Operation Mode
There is an ability operation mode for Fail-safes due to low or high ambiance temperature.
If HDD data can be read, fail-safe is shown, then normal displays are displayed only for functions which can be
operated.
RELEASE CONDITIONS OF FAIL-SAFE
Fail-safe is released on following conditions and normal mode is restored.
When The Temperature of HDD Is Low or High
If the ambient temperature becomes out of fa il-safe condition range, normal mode is restored.
