Mitsubishi Outlander XL. Manual — part 853
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.
