Rear Wiper and Washer

GENERAL INFORMATION

REAR WIPER AND WASHER

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 2 times, then intermittently at 8-second intervals.

- If the selector lever (or gearshift lever) is moved to the "R" position when the rear wiper and washer switch is turned to the "INT" position and the ignition switch at "ACC"
or "ON" position, the transmission range switch (or backup light switch) "R" turns ON. 1 second later, the ETACS-ECU causes the rear wiper to operate continuously 2 times to ensure good rearward visibility.
The ETACS-ECU then causes the rear wiper to operate intermittently again at 8-second intervals.

REAR WASHER OPERATION

- If the rear wiper and washer switch is turned to the ON (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 second. After the rear washer switch signal turns off, the rear wiper signal turns off in 3 seconds.

- If the rear wiper and washer switch is turned to the ON (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 wiper returns to the intermittent mode.

DESCRIPTION OF CONSTRUCTION AND OPERATION

Rear wiper control [Initial condition: 8 seconds (without successive operations)]





1. When the rear wiper switch on the column switch is turned ON while the ignition switch is in ACC or ON position, ETACS turns the rear wiper relay ON for 3 seconds (for approximately 2 cycles) and operates the intermittent action in 8 seconds interval.
When the selector lever is moved to R (reverse) position during the rear wiper operation, the transmission range switch R (reverse) turns ON, and one second after that, ETACS turns the rear wiper relay ON for 3 seconds (for approximately 2 cycles), and operates the intermittent action in 8 seconds interval again.

2. By the special operation of the rear wiper switch on the column switch (2 consecutive operations), the rear wiper can operate continuously regardless on the set intermittent time.

NOTE:
Using the customization function, the rear wiper intermittent time can be adjusted. (Refer to Rear Wiper and Washer.)

Rear wiper linked with washer function Initial condition: with function





When the rear washer switch on the column switch is turned ON while the ignition switch is in ACC or ON position, ETACS turns the rear washer relay ON.
The rear washer relay turns ON after the rear washer switch has been ON for 0.3 seconds, then turns the rear wiper relay ON to operate the rear wiper simultaneously. When the rear washer switch is turned OFF, after 3 seconds the rear wiper is turned OFF.
If the rear washer switch is turned ON during the rear wiper operation, 7.4 seconds after turning OFF the rear wiper relay turns OFF, the intermittent action is resumed in 8 seconds interval.
NOTE:
Using the customization function, the washer linked rear wiper function can be invalidated.
