Top suspect would be the alignment of the IR sensors.  You may have to do some adjustment on the chuff switch as well.

Of course, there's always the possibility that the wiring has a problem from the chuff switch to the motherboard where the R4LC lives.  Since the chuff switch is on a articulated truck, those wires get flexed a lot.
