Looking for your input, on a 12 stop 311. About 3 weeks ago I kept getting a 2906 ,SAF ETP relay picked at terminals. The car would be either at 1 or 12doors closed with no traps. So, going with the suggested fix I replaced the ETP relay and know problem for 3 weeks. Now today, I got the same failure at same floor. I plan to replace the ETP and the X relay next to it on my next visit but I'm asking if there's another underlying issue related to the Top/Bottom landing that I'm overlooking. *When I test at each floor 2 thru 11 2906 doesn't generate. Thx in advance.
