REAR WIPER AND WASHER
.
Rear wiper control
If the rear wiper switch of the column switch assem-
bly is turned ON with the ignition switch in the ACC
or ON position, the ETACS-ECU will turn the rear
wiper drive signal ON for three seconds (approxi-
mately two operations), and then will carry out inter-
mittent operation in a 7.4 to 8-second cycle. If the shift lever is moved to the "R" position when the
rear wiper switch of the column switch assembly is
turned ON and the ignition switch is in any position
other than OFF, the back up light switch "R" position
switch turns ON. One second later, the ETACS-ECU
turns the rear wiper drive signal ON for three sec-
onds (approximately two operations), to clear the
rear view, and then returns to intermittent operation
at a 7.4 to 8-second cycle.
.
REAR WASHER CONTROL
When the ignition switch is at the ACC or ON posi-
tion, if the rear washer switch of the column switch is
turned ON, the ETACS-ECU turns ON the rear
washer relay. The rear wiper drive signal is turned
ON in 0.3 seconds until three seconds after the rear
washer switch goes OFF to operate the rear wiper
continuously. If the rear wiper is in intermittent operation when the
rear washer switch is turned ON, 7.4 seconds after
the rear wiper drive signal turns OFF, the 8-second
cycle intermittent operation will continue.
