Hey Mr.GreenPants do you have any info on a DBF fault. The car runs on inspection fine. When you put back into auto it will correct down to the nearest floor and then run to the bottom floor. Once it stops it shuts down on a DBF status. None of the fault lights on the VVVF drive fault board are lit. For some reason the book we have which seems to have a ton of information on everything else, says nothing about this fault. For a bit of history I got called out to this job because the route guy was having brake problems with the small circuit board behind the power terminals on the drive. I believe the output was BX1 and BX2 which pick the brake relay. The board was sent to the repair shop and re-installed. Then we got side tracked into the RS car call problem which is still pending but I will need to fix the fault condition first. I have since learned that the fault is a drive brake fault, but I have no other information than that. I'd appreciate any info you can give me.
