CIRCUIT OPERATION

｠

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

｠

The ETACS-ECU operates the rear wiper according
to the following switches:

｠

Ignition switch (ACC)

｠

Rear wiper switch

TECHNICAL DESCRIPTION (COMMENT)
If  the  rear  wiper  does  not  work  normally,  the  input
circuit system from the switches, the rear wiper motor,

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

TROUBLESHOOTING HINTS

｠

The rear wiper motor may be defective

｠

The  column  switch  (windshield  wiper  and  washer
switch) may be defective

｠

The ETACS-ECU may be defective

｠

The  wiring  harness  may  be  damaged  or  the
connectors may have loose, corroded or damaged
terminals, pushed back in the connector
