HIGH SPEED OPERATION (Rain sensing)

When the front wiper switch is turned to INT position, power is supplied

through 20A fuse [No.34, located in fuse block (J/B) No. 2]
to front wiper relay terminal 1
through front wiper relay terminal 2
to BCM terminal 128, and
to front wiper rain relay terminal 1
through front wiper rain relay terminal 2
to BCM terminal 126 and
to front wiper motor terminal 4

Ground is supplied

through front wiper motor terminal 5
to front wiper rain relay terminal 5
through front wiper rain relay terminal 3
to front wiper switch terminal 14
through front wiper switch terminal 13
to front wiper relay terminal 3
through front wiper relay terminal 5
to grounds E24, E42 and E62.

The desired interval time is input

to front wiper switch terminal 19
from BCM terminal 48
to BCM terminal 49

from combination meter terminal 18 (vehicle speed signal).

The desired interval time is output

to front wiper relay terminal 2
from BCM terminal 128
through BCM terminals 56 and 113
to grounds M24 and M114.

With power and ground supplied, the front wiper relay is activated. When activated, an intermittent ground is supplied

to front wiper motor terminal 6
through front wiper rain relay terminal 4
to front wiper rain relay terminal 3
through front wiper switch terminal 14
to front wiper switch terminal 13
through front wiper relay terminal 3
to front wiper relay terminal 5
through grounds E24, E42 and E62.

Front wiper motor operates at desired interval with BCM terminal 9 grounded. Intermittent operation can be adjusted from

Approx. 0.9 - 45 sec. (When vehicle is stopped)
Approx. 0.4 - 30 sec. (When vehicle is running)

Judgment on vehicle stopped or running

Stopped -> Running: More than 5 km/h (3 MPH)
Running -> Stopped: Less than 2 km/h (1 MPH)
