If you have the tool, you should be able to go to the show PIO section and look at the Door limits D03 and D017, to see if they agree with the signal at the input board you can do the same for the output D07 door close and D010 open signal. if the cpu signal for D07 is 1, then the D07 output signal should turn green. could be a bad input card, or output card. however, if D07 is coming on and the doors still dont close for 12 seconds, then it is something in the door board or wiring to it. good luck
