ETACS calculates the windshield intermittent wiper interval
T1 from the position of the windshield intermittent wiper
switch on the column switch and the vehicle speed signal
(sent from the TCM to ETACS via CAN communication).

NOTE:

Using the customization function, the vehicle

speed-dependent intermittent function can be
invalidated. (Refer to P.51B-48.)

When  ETACS  receives  the  ON  signal  of  the  windshield
intermittent wiper switch, it turns the windshield wiper drive
signal  ON.  When  the  wiper  reaches  the  stop  position,  the
windshield  wiper  auto-stop  signal  turns  OFF,  and  the
windshield wiper drive signal turns OFF.
When  the  intermittent  time  T1  calculated  by  step  1  has
elapsed  after  the  windshield  wiper  drive  signal  ON,  the
windshield wiper drive signal turns ON again, and the above-
mentioned operation is repeated.

turned ON, the windshield wiper drive signal turns ON.
Also, the wiper speed switching relay turns ON (HI),
and the windshield wiper operates at high speed.
