Does the alarm go away when you set the parking brake?

Customer: replied 4 months ago.
I have also checked the jacks and they are all the way up
Expert:  Robert replied 4 months ago.

OK

What is the make and model of the RV? I am just curious....

Most likely the issue is the sensor for the parking brake, when that sensor fails the alarm can go off when you are in drive, it thinks the parking brake is not released and will give an audible alarm, normally the sensor will have an air line going to it and 12 vdc wires, sometimes they are right below the parking brake valve or they can be under the front cap area. Not sure how to bypass that so the alarm stops, you could try and disconnect it and see what happens... IF you have hydrualic jacks just verify the level in the tank, it should be right below the fill port. I would think a good Frieghtliner shop would be able to diagnose this and the unit should be OK to drive if all your gauges and fluid levels are at the proper level, the only other alarm I can thing of would be for low air but if it foes away when you apply the parking brake I suspect it is the parking brake sensor.... Hope this helps some.... Robert

OK

You might want to reach out to them and see if they concur on that sensor and they can tell you the part number and exact location, they do have a technical support line for customers. Below is the contact info, from what you are describing it sounds to me like the parking brake sensor, they might be able to at least provide you a part number and location on that. I have worked on thousands of different RV's so it is always hard for me to know component location... I hope this points you in the right direction, if you are satisfied with my efforts please feel free to select a rating at the top of the page, it is the only way I get credit for helping.... Robert
