• The circuits between INPUT 1 and OUTPUT 5 and between INPUT 1 and OUTPUT 3 are formed when the

TURN RH switch and FR WIPER LOW switch are turned ON.

• BCM detects the combination switch status signal “1CE” when the signals of OUTPUT 3 and OUTPUT 5 are

input to INPUT 1.

• BCM judges that the TURN RH switch and FR WIPER LOW switch are ON when the signal “1CE” is

detected.

WIPER INTERMITTENT DIAL POSITION SETTING (FRONT WIPER INTERMITTENT OPERATION)

BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2 and 3 switches.
