WIPER AND WASHER SYSTEM SYSTEM DESCRIPTION

FRONT WIPER AND WASHER CONTROL FUNCTIONS

Control/Function	Description
Wiper speed regulation	Maintains the default speed of the front wipers even when the supply voltage or resistance changes.
Door Open Linked Wiper Suspend Function (w/ Rain Sensor)	Stops the front wipers when the wiper switch assembly is in the AUTO position, the shift lever is in P and the driver door or front passenger door is open. Tech Tips The front wipers stop at their lowermost position for 0.3 seconds, and then move to the park position. AUTO control restarts when the door is closed.
Wiper speed HI to LO transition control	Smoothly controls the change in speed of the wipers when the wiper speed is switched from HI to LO.
Service position control	Moves the front wipers to the uppermost positio when the windshield wiper switch assembly is held in the MIST position for 2 seconds or more within 42 seconds of the engine switch being turned off. Tech Tips The front wipers can be returned from the service position by turning the engine switch on (IG) and operating the front wipers by moving the wiper switch assembly to any position. When the windshield wiper switch assembly is moved to the MIST position when the front wipers are in the service position, the front wipers will return to the park position. The front wipers must be in the service position when locking back* the front wipers. When the front wipers are returned from the service position, the wipers operate at a slow speed for the first cycle to minimize damage to the engine hood if contact with a front wiper arm occurs due to it being in the lock-back position. Also, if a front wiper arm contacts the engine hood, the will be are stopped after being moved a short distance in reverse.
Engine hood interference damage reduction function	Operates the windshield wiper motor at a slow speed for the first cycle when the front wipers are returning from the service position to minimize damage if a wiper arm in the lock-back position contacts the engine hood. Moves the front wipers a short distance in reverse if a wiper arm in the lock-back position contacts the engine hood and the windshield wiper motor locks up.
Self locking control	Holds the wipers in the park position when the engine switch is on (IG).
Maintenance position control	Moves the front wipers to the center position when the windshield wiper switch assembly is moved to the MIST position 6 times in 2 seconds after the engine switch being turned off. Tech Tips The maintenance position is used when performing work on the front suspension.
Protection mode	Monitors the current, speed and temperature of the front wiper motor in order to protect the system. Tech Tips Overload protection, which operates in situations such as when the front wipers and operates them in INT is dry, reduces the speed of the front wipers and operates them in INT in order to reduce wear. Snow protection operates when accumulated snow at the extremities of the front wiper movement interferes with operation. In this situation, the front wipers will temporarily stop and push the snow. If the snow cannot be cleared, the wipers reverse direction and then continue. Excessive load protection operates when a foreign object near the center of the wiper movement interrupts the wiper movement. In this situation, the wipers temporarily stop and push the foreign object 25 times. If the foreign object cannot be cleared, the wipers will stop.
MIST function	Operates the wipers in LO when the windshield wiper switch assembly is held in the MIST position.
Auto operation	Operates the wipers as requested by the rain sensor when the windshield wiper switch assembly is in the AUTO position.
Vehicle speed linked wiper intermittent operation control	Controls the delay of the wipers when the windshield wiper switch assembly is in the INT position. Tech Tips The period of delay is controlled by the auto sensitivity adjustment switch on the windshield wiper switch assembly. The period of delay changes in accordance with vehicle speed. When the windshield wiper switch assembly is in the INT position and the vehicle is stopped, the wipers operate for 1 cycle when the vehicle starts off. When the auto sensitivity adjustment switch on the windshield wiper switch assembly is moved to a faster position, the delay is reset and control begins according to the new setting.
Washer cooperation	When the front washer switch is operated for 0.5 seconds or more, the front wipers operate in LO. When the front washer switch is released, the front wipers operate in LO for 3 cycles. Note If the front washer switch is operated for 40 seconds or more, operation of the washers is stopped to prevent burnout of the washer motor and pump assembly, and the wipers return to the park position.
Drip prevention wiper function	3 seconds after washer cooperation operation ends, operates the front wipers for 1 cycle to remove any remaining washer fluid from the windshield glass. Tech Tips This function only operates when the vehicle is stationary or when the vehicle is being driven at less than 4 km/h (2 mph).
Vehicle stopped wiper control	If the vehicle is stopped with the windshield wiper switch assembly in the LO position, the front wipers will operate for 3 cycles and then automatically change to intermittent operation with an interval of 2.5 seconds.
Washer nozzle heater (w/ Washer Nozzle Heater)	The washer nozzle heater system operates when the ambient temperature drops to 5°C (41°F) or less while the ignition switch is on. The washer nozzle heater system stops operating when the ignition switch is turned off, or when the ambient temperature reaches 6°C (42°F) or higher while the ignition switch is on.

*: Function to allow the wiper arms to be folded back, such as when replacing the wiper blade.
