ELECTRICAL 112 AUTO WIPE: Under the “Auto” position condition. If the ECU detects an error on the rain sensor the system works as following: Judge level at the fail timing Operation Wiper Speed = 0 (no wiping) Keep no wiping Wiper Speed = 0 and last wipe or “IG” OFF was less than 7 sec. before failure event. Continuous interval operation according sensitivity switch position Wiper Speed = 1 (Speed 1) Keep Speed 1 operation Wiper Speed = 2 (Speed 2) Keep Speed 2 operation Washer function Keep working as per specification After detection sensor error, if switch position changes the “Auto” _ “Another” _ “Auto” then operate continues interval as following. After detection sensor error, if IG is OFF once, after then operate continues interval as following during IG = ON and “Auto” position. In case of an Error mode for less than 7 sec. after “IG” on the ECU should operate continues interval. <Continues interval operation> Sensitivity switch position 1, 2, 3, 4 & 5 & Pause time t1, t2, t3, t4 & t5. WASH FUNCTION CONFLICT WITH AUTO WIPE When Wiper is in Auto mode and simultaneously wash switch is pressed then Wash function should override the Auto wiper function. A faulty Rain Light Sensor will not effect the wash function. Removal of the Rain Light Sensor or loosen connection with it, does not effect the functionality of wash function. Front wiper low & high speed is directly controlled by the combination switch. COMPULSORY WIPE FUNCTION: When the sensitivity level of the Rain sensor is varying from Low to High (Ex: P1 to P2), a compulsory wipe occurs. When the sensitivity level of the Rain sensor is varying from High to Low (Ex: P2 to P1), NO compulsory wipe occurs.
