Thanks to All. Problem is car wont run, except on inspection. It seems that DOZ is a necessary signal to get car into automatic service. SAFR signal is good, since doors are closed and stop switch is in run position. All inputs are correct, but car wont take a call (car or hall). It seems that the only outputs that are not on are DOZ and HBV. I dont know which is needed first, or if it matters. In the past, when the car is at rest, the DOZ light is lit. The relay on the function board is soldered in and can certainly be replaced, but a supposedly good board was substituted and the symptoms were the same. I have received an interconnection print and when I can get back to the job, I will check the molex plugs to see if it is a loose connection.
