STEP 10. Check the multi-centre display unit  power 
supply circuit [ignition switch (IG1)]. Measure the voltage 
at the multi-centre display unit  connector C-05.
(1) Disconnect the multi-centre display unit  connector C-05 

and measure at the harness side.

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 2 and ground.

• The measured value should be approximately 12 volts 

(battery positive voltage).

Q: Does the measured voltage correspond with this range?

YES : Replace the multi-centre display unit . The 

multi-centre display unit  should work normally.

for loose, corroded, or damaged terminals, or terminals pushed 
back in the connector. If junction block connector C-211 or 
C-215 is damaged, repair or replace the wiring harness. Refer 
to GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between multi-centre display unit  

connector C-05 (terminal 2) and ignition switch (IG1) in 
good condition?
YES : 
The procedure is complete.
NO :  Repair the wiring harness. The multi-centre display

INSPECTION PROCEDURE 3: The A/C Display Shows "COMMUNICATION ERROR", and then can not 
Proceed to Next Screen.

.

CIRCUIT OPERATION

The multi-centre display unit  receives information on 
current A/C operation condition from the A/C-ECU 
via CAN bus lines.

.

TECHNICAL DESCRIPTION (COMMENT)

The multi-centre display unit  will show "COMMUNI-
CATION ERROR" message if it has received abnor-
mal data from the A/C-ECU via CAN communication 
for 60 seconds or more. Then the A/C operation 
screen, which is based on the last normal informa-
tion, continues to be shown. If the communication 
returns to normal, "COMMUNICATION ERROR" 
message will disappear and the A/C operation 
screen will return to normal.
