CIRCUIT OPERATION
The windshield washer switch sends a signal through
the column-ECU (incorporated in the column switch)
to  the  ETACS-ECU.  If  the  column-ECU  sends  a
windshield washer switch "ON" signal to the ETACS-
ECU,  the  ETACS-ECU  turns  on  the  relay
(incorporated in the ETACS-ECU), thus causing the
washer motor to be turned on.

TECHNICAL DESCRIPTION (COMMENT)
If the windshield washer does not work normally, the
washer  motor,  the  column  switch  (windshield  wiper

and  washer  switch)  or  the  ETACS-ECU  may  be
defective.
