SYSTEM DESCRIPTION

1 FRONT WIPER SYSTEM




a The front wiper system receives the wiper operation signal from the combination switch, and the passenger side J/B ECU operates the wiper motor.
b The passenger side J/B ECU adjusts the intermittent interval having considered the vehicle speed, brake signals, etc. and determined the vehicle driving and stopping conditions when the wiper motor is operating intermittently from directions from the combination switch. The system has the following functions.

2 FRONT WASHER SYSTEM
a The front washer system receives the wiper operation signal from the combination switch, and the front light ECU operates the washer motor.

3. CONTINUOUS FRONT WASHER WIPER SYSTEM
a The continuous front washer system receives the washer operation signal from the combination switch, and the passenger side J/B ECU operates the wiper motor. The front wipers are operated 3 times after the front washer is stopped.
b The front wiper stops after operating 3 times from the point where the front washer switch has been ON for more than 40 seconds continuously. The front wipers are then operated 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 the rainfall, to the passenger side J/B ECU. The front wipers operates when the windshield wiper switch is in the AUTO position. The rain sensor sensitivity can be adjusted by the rain sensor adjusting switch.
b. In this system, the passenger side J/B ECU receives the vehicle speed signal from the combination meter, and operates the front wipers according to the vehicle speed.
c. The passenger side J/B ECU adjusts the intermittent interval having considered the vehicle speed, brake signals, etc. and determined the vehicle driving and stopping conditions when the wiper motor is operating intermittently from directions from the rain sensor.

5. HEADLAMP CLEANER SYSTEM
a The headlamp cleaner system operates when the headlamps are ON and the headlamp cleaner switch is pushed (ON). It also operates when the headlamps are ON and the front wiper washer system is operating. It does not, however, operate when the daytime driving light system is operating.
