GENERAL DESCRIPTION

M1511000100138

OPERATION
Rear Wiper Operation

•

If the rear wiper and washer switch is turned to
the "INT" position with the ignition switch at
"ACC" or "ON" position, the ETACS-ECU causes
the rear wiper to operate continuously two times,
then intermittently at eight-second intervals.

•

If the selector lever is moved to the "R" position
when the rear wiper and washer switch is turned
the "INT" position and the ignition switch at
"ACC" or "ON" position, park/neutral position
switch "R" turns ON. One second later, the
ETACS-ECU causes the rear wiper to operate
two times continuously to ensure good rearward
visibility. The ETACS-ECU then causes the rear
wiper to again operate intermittently at eight-
second intervals.

Rear Washer Operation

•

If the rear wiper and washer switch is turned the
"WASHER" position with the ignition switch at
"ACC" or "ON" position, the rear washer ON
signal is sent to the ETACS-ECU, causing the
rear wiper signal to turn on after 0.9 seconds.
After the rear washer switch signal turns off, the
rear wiper signal turns off in three seconds.

•

If the rear wiper and washer switch is turned to
the "WASHER" position while the rear wiper is at
intermittent mode, the rear washer works for that
period when the washer switch remains on. Then
the rear wipers return to the intermittent mode.
