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

  T1 : 0.2 ± 0.03 sec,
  
  T2 : 0.06 ~ 0.2sec, T3 : 0.7 ± 0.1 sec
  
  T3 = 0 (In case of T2 ≤ 0.06 sec.)
2. Turn Wiper Enable Relay ON after T1 when turning Washer switch ON at the status of IGN2 ON and if the input of Washer switch is more than 0.2sec, turn the output of Wiper Enable Relay OFF for 2.5~3.8 sec after turning Washer switch OFF.
  But, ignore the input of Washer switch occurred while Wiper Enable Relay is being operated and accept it from the input of Washer switch after operating Wiper Enable Relay.

  T1 : 0.2 ± 0.02s,
  
  T2 : over 0.2s,
  
  T3 : 2.5 ~ 3.8s
3. Turn the output of WASHER INTERLOCKING WIPER when Washer switch is turned ON for more than 0.2 sec during the operation of INT WIPER. If Washer switch is turned on for less than 0.2sec, turn the output of Wiper Enable Relay once.

  T1 : 0.2 ± 0.02s,
  
  T2 : over 0.2s,
  
  T3 : 2.5 ~ 3.8s,
  
  T4 : INT TIME - 0.7s,
  
  T5 : 0.2 ~ 0.06s,
  
  T6 : 0.7 ± 0.1s
4. In case of starting (IGN1 ON & IGN2 OFF) ignore the input of Washer switch.
Mist Interlocking Wiper
1. Turn the output of Wiper Enable Relay for 700ms when turning Mist switch ON at the status of IGN2 ON.

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