I have a 2004 Nissan Titan LE 4x4. I've noticed recently during hiway driving in 2 wheel drive my "Transfer 4LO position indicator light" flashes alternatly with the flashing of the "4WD shift indicator light". Whenever I get off the road and put it in 4WD, both high and low work fine. I have also run the judgement self diagnosis which shows your start signal and the flickering of the 4WD warning lamp, to check this problem out. The flickering pattern was a total of 9 blinks. It is telling me that there is more than two switch inputs simultaneously detected due to short circuit of 4WD shift switch. That's as far as the information I have takes me. Can you please steer me in the right direction? Also, while looking under the hood on the drivers side there is a loose hose that comes up next to the air cleaner box and does not connect to anything. The other end of the hose is connected to the top side of the front drive unit. Is this correct that the top of this hose is not connected to anything?
I have the same problem with mine flashing did u find out what it was
As far as your 4WD light problems, can't help you. The loose hose sounds like the front diff vent hose.
