INSPECTION PROCEDURE 4: Rear washer does not work normally.

.

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.

.
