Mitsubishi Outlander GS45X. Manual — part 1361
WINDSHIELD WIPER AND WASHER
TSB Revision
EXTERIOR
51-67
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.
.
TROUBLESHOOTING HINTS
• The wiring harness or connectors may have
loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector
• The washer motor may be defective
• The column switch may be defective
• The ETACS-ECU may be defective
