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.
