Home Forums General Discussion Technical Questions Otis Mrq dbf fault

Hey guys,the car was at the floor doors open with please exit light on.Had a dbf fault,the doors would try to close then reopen.I put it on insp. to see if it would run,it did and never messed up again.What should I look for next,I know it'll come in again?Ive had connection problems in the past.We also changed an Rs board that was in the drive circuit last year that I think fixed a similar problem.Any suggestions?thanks

had issues with break switch on these units, also the relay contacts go bad quite often.

dbf is caused by any contact on u or d relay and ud if you have one...trust me

btw check ur contacts on ohms with ur meter
