Wiper Control

WIPER Control coupled with Washer
1. Under IGN2 SW ON, WIPER RELAY is turned ON after T2 from WASHER SW ON if WASHER SW is ON for T1 and WIPER RELAY is turned OFF after T3.

2. Under IGN2 SW ON, WIPER RELAY is turned ON after T2 from WASHER SW ON if WASHER SW is ON for at least T1, and WIPER RELAY is turned OFF after T3 from the moment that WASHER SW is turned OFF.

3. Operation in Item (2) is performed if WASHER SW is ON for at least T1 during WIPER operation with INT SW. Operation in Item (1) is performed if WASHER SW is ON for T6.

  T1 0.6s(MIN), T2: 0.3s ± 0.03s,
  
  T3 2.5s ~ 3.8s (2 ~ 3 TURN),
  
  T4 T5 ~ 0.7s, T5: INT TIME,
  
  T6 0.2s ± 0.59s, T7: 0.7s ± 0.1s
4. Operation is cancelled in case IGN is OFF during T3.
5. Give priority to WASHER interlocking WIPER than Speed sensing INT WIPER function.
6. WASHER SW signal input shall be ignored at start-up (IGN1 ON & IGN2 OFF states).
SPEED SENSING INT WIPER
1. WIPER intermittent time is controlled by car speed.
  Under IGN2 SW ON & INT SW ON states, car speed and INT VOLUME value are acquired and intermittent time is calculated. Then, WIPER intermittent time is automatically converted.
MIST Control coupled with WIPER
1. Under IGN2 SW ON, WIPER RELAY is turned ON directly from MIST SW ON if MIST SW is ON for T1 and WIPER RELAY is turned OFF after T2.

2. Under IGN2 SW ON, WIPER RELAY is turned ON directly from MIST SW ON if MIST SW is ON for at least T1, and WIPER RELAY is turned OFF after T3 from the moment that MIST SW is turned OFF.
