I’ve got a group of 5 T4 passenger cars, 10 stops each, car 3 is down for a repair, but all other cars are getting a fault 16 and the status on IMS says DISP LOSS about every other run and was getting them before car 3 went down. After about 3-5 seconds of the status saying DISP LOSS each car will reset itself and continue to run except cars 2&5 are starting to fault out and not want to reset itself after so many resets. It used to happen intermittently and the cars would all go into emergency dispatching but I sent the CPU for car 1 off for repair and then the fault went away for almost a year. It’s starting to come back with a vengeance now and I’m not sure where to start again. The cars are not yet going into emergency dispatching but I’m sure it is coming in the near future. Very high profile customer that doesn’t like down elevators if you catch my drift. I’ve changed the back up batteries, changed my voltage monitors, reseated all my boards, checked my power supplies, and checked my daisy chain wiring for my group. Really hard to pinpoint where my issue is coming from. Any help would be greatly appreciated.
