SYSTEM DESCRIPTION
1. FRONT WIPER SYSTEM
a. When the front wiper system receives a wiper operation signal from the combination switch ECU, the front controller operates the wiper motor.
b. While the wipers are operating in intermittent mode from directions from the combination switch, the front controller adjusts the interval between movements of the wiper arm, according to vehicle speed, brake signals, and driving and stopping conditions. The system has the given functions:
2. FRONT WASHER SYSTEM
a. When the front washer system receives a wiper operation signal from the combination switch ECU, the front controller operates the washer motor.
3. CONTINUOUS FRONT WASHER WIPER SYSTEM
a. When the continuous front washer system receives a washer operation signal from the combination switch ECU, the front controller operates the wiper motor. The front wiper arms continue operation for 3 times after the front washer is stopped.
b. The front wipers stop operating 3 times after the front washer switch has been ON for more than 40 seconds continuously. The front wipers then operates once at an interval of 3 to 7 seconds. The interval is determined by the vehicle speed signal received from the combination meter.
4. AUTOMATIC WIPER SYSTEM
a. In the automatic wiper system, the rain sensor mounted in the upper portion of the windshield sends a front wiper operation command, according to the amount of rainfall, to the front controller. The front wipers operate when the windshield wiper switch is in the AUTO position. The rain sensor sensitivity can be adjusted by the windshield wiper switch's adjusting volume.
b. In this system, when the front controller receives a vehicle speed signal from the combination meter, and operates the front wipers according to the vehicle speed.
c. While the wiper motor is operating intermittently from directions from the rain sensor, the front controller adjusts the interval only in auto mode between movements of the wiper arm, according to vehicle speed, brake signals, and driving and stopping conditions.
