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 wind-
shield and rear washer motor, the column switch
(windshield wiper and washer switch) or the
ETACS-ECU may be defective.
