outputs to the audio circuits one after the 
other for 1 second. 

Speaker Test 100 Hz

Display-Test

—

This provides a test sequence where 
test displays (plain colored display: e.g. 
white, black, red, blue, green) are shown 
one after the other. 
The respective color is shown for an in-
dicated period of time (parameter). After 
the display test, the design of the display 
previously available is stored. While the 
screen shows a plain colored display, a 
pixel malfunction may be detected.

Self Test

• SD Card Access 
• BT Module Access
• GPS Antenna
• Radio Antenna
• DAB-Antenna

A system self test is executed and the 
results are stored into the error memory.

CONSULT Function

INFOID:0000000010714807

CONSULT FUNCTIONS

CONSULT performs the following functions via the CAN communication with the around view monitor control
unit.

ECU IDENTIFICATION

Around view monitor control unit part number can be identified.

SELF DIAGNOSIS RESULT

• Refer to 

AV-120, "DTC Index"

.

• In CONSULT 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] and [U1010] is detected. The counter

increases by 1 if the condition is normal at the next ignition switch ON cycle.

Freeze Frame Data (FFD)

The following vehicle status is recorded when DTC is detected and is displayed on CONSULT.

DATA MONITOR

NOTE:
The following table includes information (items) inapplicable to this vehicle. For information (items) applicable
to this vehicle, refer to CONSULT display items.
