FRONTWIPER CONTROLLER ( Fig. 44) Function It generates the variable time delay during the Intermittent wipe operation of the wipers on the vehicle. Location Behind glove box on fire wall. Connection details Performance check ● When the intermittent input (Ter. D) goes high, Ter. A should get connected to Ter. B for one wipe cycle ( The unit assumes the wipe cycle is completed when Ter. C goes to GND from VCC level). Then for time 't' seconds (the time should vary from 2 to 15 second with the resister R varying from 0 to 64 K) Ter. A and B should be disconnected. Again Ter. A and B get connected for one wipe cycle. This cycle continuous until Ter. D is high. ● When wash input (J) becomes active output Ter. A should get connected to terminal B after 0.7 sec. and when Ter. J goes low Ter. A get disconnect from Ter. B after 2 sec. The wash should have higher priority than the intermittent signal. ● When the Ter. H is low the wash function should be ignored.
