  T1: 0.3±0.03sec, T2: 0.06~0.2sec, T3: 0.7±0.1sec, T2 is less than 0.06sec: T3=0
2. Turn Wiper 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 relay off for 2.5 ~ 3.8sec after turning washer switch OFF.
  But, ignore the input of Washer switch occurred while Washer interlocking Wiper is being operated and accept it from the input of Washer switch after operating Washer interlocking Wiper.

  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 Relay is ON and if Mist switch is turned OFF turn the output of Wiper Relay for 700ms from that point.
3. Ignore the input of Mist switch while operating WIPER by INT WIPER, WASHER Interlocking WIPER.

Rear Washer Inter Locking Rear Wiper
1. Rear Wiper Realy is turned ON after T1 When Rear Washer switch is turned ON at the status of IGN2 ON. If input of Rear Washer switch is less than 0.2sec and more than 0.06sec, Rear Wiper Realy is turned OFF after T3. Ignore the input of Rear Washer switch operating Rear Washer interlocking Rear Wiper accepts the input of Rear Washer switch after the operating Rear Washer interlocking Rear Wiper.

  T1: 0.3 ± 0.03sec, T2: 0.06 ~ 0.2sec
  
  T3: 0.7 ± 0.1sec, T2 is less than 0.06sec: T3=0
2. Rear Wiper Relay is turned ON after T1 When Rear Washer switch is turned ON at the status of IGN2 ON. If input of Rear Washer switch is more than 0.2sec, output of Rear Wiper Relay is turned OFF after output of Rear Wiper Relay is turned ON for more than 2.5sec and less than 3.8sec after Rear Washer switch OFF. Ignore the input of Rear Washer switch operating Rear Washer interlocking Rear Wiper accept the input of Rear Washer switch after the operating Rear Washer interlocking Rear Wiper.
