Does anyone know how to by pass the “not in park” interlock on this system? Parking brake is set, but HWH control panel shows brake not set, therefore will not allow air bags to dump.

The manual for my 310 system shows a wiring connection to the dash park brake light , but shows no indication if its a ground circuit to signal the control box .
I'll look over my 99 F/L schematics to see if the park light is switched to ground .

Perhaps Winnebago wiring would provide an answer , I don't believe that Freightliner wiring would be of any help.

Ok the Freightliner brake system switch ( for the light ) is a switch to ground .

First question ; is the dash light for the park brake on ?
If not you probably have a bad sensor in the park brake system.

If I'm reading this 310 system wiring correctly , finding the wire that should be attached to the park brake warning light and grounding it should be your override .

Wire in position 6 in the 15 wire connector on the control box , should be labeled 9000 or 9001 .

Yes light on dash is on. Could not figure if I should ground the #6 wire or not. Will try that tomorrow. Wires are not numbered. Thanks!

I am sure there is a grounding problem, just have not found the ground lug.
Went across about 10 miles of I-40 that shook the devil out of the coach.

The electric mirrors stop working, overhead fans shut off, slides went out about 1-1/2”, and HWH buzzer came on. Drove it with alarm on to camp site. That is when I discovered air bags would not dump because of brake indicator.
Appreciate all the help you give us!

I don't know what kind of front power distribution board/fuse panel , Winnebago uses , but with all those failures , you could have had a multiple connector come off the board , if you have one that looks like this .

No does not look like that, but I also think i am looking for something similar
Think I am on the right path after reading your posts. Will continue, lucky this does not prevent the use as long as site is fairly level.

Thanks for trying to help me with my problems, I checked #6 wire it has voltage. Therefore I did not ground it as I was afraid I would short something out.
Maybe I did not make myself clear on the key pad it “brake not set” is on as is the dash light. Starting to think maybe I have control module issues. But slides work...
Since lights work I would think ground wires to frame is ok. Ground lug on control module tight. Ground lug on steering tight.
I am now in Yuma for the winter and motorhome in storage. Will continue to try to figure out the problem, but not impacting our travels.
Thanks again
