Home Forums General Discussion Technical Questions Ok here's a good one on a TIV for you guys

I have a bank of 2 cars and car 2 will not take a hall call to the lowest landing and will not take a down hall call from the 2nd landing!? It will take a car call to the lowest landing though. Also if I give that car directly an SUC1 command it will go to the lowest landing as if it were a hall call. Car 2 has the latest and greatest (I say that with a grain of salt) generic software. Car 1 has older software. I have looked into almost all the parameters and commands both for car and group and everything seems to be in order. There is no security block or anything. I just can't seem to find out what is going on. Any and all help greatly appreciated! And I have changed the input and output modules for the 1u and also 2d.
