CONSULT-III Function (MULTI AV)INFOID:0000000003765658
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.

Diagnosis mode Description
Ecu Identification The part number of AV control unit can be checked.
Self Diagnostic ResultPerforms a diagnosis on the AV control unit and a connection diagnosis for the communication
circuit of the Multi AV system, and displays the current and past malfunctions collectively.
Data Monitor The diagnosis of vehicle signal that is input to the AV control unit can be performed.
AV communicationAV&NAVI C/UDisplays 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.
