Description on System Operation
Wiping mode
1. Wiper switch is turned on, relay 1 on CONT turns on to rotate the motor clockwise.
2. When "W" and "C" points on the CAM switch are connected during revolution, relay 1 on CONT turns off and then
relay 2 turns on to rotate the motor counterclockwise.
3. If "W" and "C" points on the CAM switch are connected during revolution again, relay 2 on CONT turns off and then
relay 1 turns on to rotate the motor clockwise. It means by changing motor polarities between 2 and 4 with CAM
switch, the wiper operates.
Parking mode operation
1. Parking while operating clockwise: If turns off wiper switch during wiper operation, "W" and "C" points on the CAM
switch are connected during revolution, then relay 1 on CONT turns off to stop the motor. After 1 second, relay 1 on
CONT turns on to rotate the motor clockwise and then "P" and "C" grounds on the CAM switch are connected to turn
off relay 1 on CONT and to stop motor.
2. Parking while operating counterclockwise: If turns off wiper switch during wiper operation, "W" and "C" points on the
CAM switch are connected with ground during revolution, then relay 2 on CONT turns off to stop the motor. After 1
second, relay 2 on CONT turns on to rotate the motor counterclockwise and then "P" and "C" grounds on the CAM
switch are connected to turn off relay 2 on CONT and to stop motor.
Washer mode operation
When washer switch is turned on for over 0.5 sec., wiper mode operates 2 times and then performs parking mode
operation to stop motor.
However, when washer switch is turned on for less than 0.5 sec., wiper motor does not operate.
Limit switch ON mode operation
1. Limit switch ON during wiper operation: If turn on limit switch during wiper operation, returns to parking position
immediately to stop the motor.
2. Limit switch ON under parking position: Even when the wiper switch or INT switch is turned on, the motor does not
operate.

System operation description
1. If turn on motor operation switch, relay 1 on controller
turns on to rotate the motor clockwise (operation order:
(1) → (2) → (3) → (4))
2. When "W" and "C" points on the CAM switch are
connected during revolution, relay 2 on controller turns
off and relay 1 on controller turns on to rotate the motor
clockwise. It means by changing motor polarities between
wiping ranges with CAM switch, the wiper operates.

(operation order: reciprocates (2) → (3) → (4) → (3) →
(2))
3. DSP angle means angle between (1) and (2) or (1) and
(4).
4. If rotates from (3) to (4) in clockwise, the motor parks in
position (1). If rotates from (3) to (2) in counterclockwise,
the motor parks in position (1).
It means when motor is in park position, "W", "C" and "P"
points are in a line as shown in below.
