ZC6008710005

Connector: A-54

ZC6008780022

Connector: C-304

 

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

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

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