CONSULT-III FUNCTIONS

CONSULT-III performs the following functions via the communication with the AV control unit.

Diagnosis mode
Description
Ecu Identification
The part number of AV control unit can be checked.
Self Diagnostic Result
Performs 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 COMMUNICATION

When “AV communication” of “CAN Diag Support Monitor” is selected, the following function will be performed.

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.

 
 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 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.
