Description

The Rain sensing windshield wiper system is a wiper system that, in addition to providing normal wiper functions off, mist, manual low speed, manual high speed, and wash, provides automatic control of automatic intermittent automatic low, and automatic high speeds.

When the ignition key is in the ON position, the rain sensor will be activated.

Operation Control

Wiper ECU transmits the signal as a rain sensor, and then the rain sensor perceives the rainwater to transmit to the wiping order wiper ECU, wiper ECU controls the wiper motor according to the signal.

Auto Operation

1. Operation Condition OPERATION CONDITION Operation mode Operation condition Direct mode Switch AUTO is basic operation condition that rain sensor perceives dry windshield. From this condition, the rain sensor decides the wiper operation mode depend on the quantity and time of measured rainwater Intermittent mode Operation pauses between 0.5 ~ 5 seconds, then the wipers switch to intermittent mode Low speed Operate continuously at low speed High speed Operate continuously at high speed
2. Safety Function

1. When there is an ice in the sensing field, the rain sensor cannot recognize the correct working condition. NOTE: Do not operate the rain sensing wipers unless the windshield is completely clear of ice and snow.
2. Glass damage : rain sensor cannot perceive the damaged windshield within the sensing field.
3. The rain sensor will not operate properly if detached from the windshield.
4. If the wiper ECU does not transmit any effective data in 5 seconds, the rain sensor turns off LED.
5. If the intermittent wiper signal is interrupted for >2 sec, the wipers are moved to the parking position.
6. If a rain sensor signal communication error lasts for >5 sec, the wipers are moved into the parking position.
7. If the rain sensor transmits an error to the wiper ECU, the wiper ECU stops the AUTO function after 4.5 seconds.
