This error relates to the shunting switch or anti crush switch as I call it. The truck sees the switch as closed during star up. It could be that you accidentally jammed the switch in the on position when installing the card. If this is ok, check wiring connections and the switch in case it is a faulty unit. If you have Judit you can connect and see if the switch is open or closed
