WASHER INTERLOCKING WIPER
Turn Wiper Enable Relay ON after T1 when turning Washer SW ON at the status of IGN2 ON and if the input of Washer SW is between 0.06 and 0.2sec, turn the output of Wiper Enable Relay OFF after T3.But, ignore the input of Washer SW occurred while Wiper Enable Relay is being operated and accept it from the input of Washer SW after operating Wiper Enable Relay.

T1 : 0.2 ± 0.03sec, T2 : 0.06 ~ 0.2sec, T3 : 0.7 ± 0.1 sec

T3 = 0 (In case of T2 ≤ 0.06 sec.)
1. Turn Wiper Enable Relay ON after T1 when turning Washer SW ON at the status of IGN2 ON and if the input of Washer SW is more than 0.2sec, turn the output of Wiper Enable Relay OFF for 2.5~3.8sec after turning Washer SW OFF.
  But, ignore the input of Washer SW occurred while Wiper Enable Relay is being operated and accept it from the input of Washer SW after operating Wiper Enable Relay.

  T1 : 0.3 ± 0.03s, T2 : over 0.6s, T3 : 2.5 ~ 3.8s
2. Turn the output of WASHER INTERLOCKING Wiper when Washer SW is turned ON for more than 0.2sec during the operation of INT Wiper. If Washer SW is turned on for less than 0.2sec, turn the output of Wiper Enable Relay once.

  T1 : 0.3 ± 0.03s, T2 : over 0.6s,
  
  T3 : 2.5 ~ 3.8s, T4 : INT TIME - 0.7s,
  
  T5 : 0.2 ~ 0.6s, T6: 0.7 ± 0.1s
3. In case of starting (IGN1 ON & IGN2 OFF) ignore the input of Washer SW.
MIST INTERLOCKING WIPER
1. Turn the output of Wiper Enable Relay for 700ms when turning Mist SW ON at the status of IGN2 ON.

  T1 : Min 60 ms, T2 : Max 100ms,
  
  T3 : 700 ± 100ms
2. If the input of Mist SW is continuous (for more than 700ms), keep the condition of Wiper Enable Relay is ON and if Mist SW is turned OFF turn the output of Wiper Enable Relay for 700ms from that point.
3. Ignore the input of Mist SW while operating Wiper by INT Wiper, WASHER Interlocking Wiper.
