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 “IGN” 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. BCM shall monitor the error state for more than a counter value after then goes in to failsafe mode. During the error detection state BCM shall use the auto wipe and auto light previous value for the light and wiper operation. Once BCM detect the No error for a particular counter value then work as per specifications. In between BCM shall take the previous LIN communication values for rain and light function. WASHER MOTOR CONTROL: If the wash switch input is coming continuously • for more than 15sec to BCM then BCM shall de-activate the washer motor. This is to protect the washer motor. Also deactivate the LIN washer bit to RLS which indicate the washer switch status. After 15Sec BCM shall ignore the wash input & • provide the wipes as per parameter 3 and wait for time specified as per parameter 5sec and provide one more drip wipe, if there is no request from RLS to activate the wiper after last wash wipe. WASH FUNCTION CONFLICT WITH AUTO WIPE When Wiper is in Auto mode and • simultaneously wash switch is pressed then Wash function should over ride 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. 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 1) Keep Speed 2 operation Washer function Keep working as per specification LV SYSTEM 174
