Jerry:
Our coach is a 2008 with HWH Air leveling and Power Gear for Hydraulic leveling, so due to the age difference, I'm not sure if yours will operate the same, but this, as we discovered, is how ours is programed.
Our Hyd reservoir was cracked and lost fluid, so with low fluid it sends a signal to warn us. With this fault, it affected both systems. We used our air system to level which worked fine, however, with the fluid being too low in the hyd reservoir, when we started the coach to leave, we could not get the system to operate in the Travel mode. By topping off the hyd reservoir the system would then sense normal operation and all systems were satisfied. We had to go through this process several times in our travel to beaver coach sales where they replaced the Hyd Reservoir and Pump. The tech did not put back in enough fluid and we got the same result ( travel mode would not respond, got a bunch of beeping when pushing the travel button), once the tech topped off the Hyd system, Air system functioned as advertised. So the two systems on our coach are related to each other in this respect. I'm not sure if this is beneficial to you, but I would make sure your Hyd system is topped off.
Good Luck
