No brake lights 2018 Allegro Bus

[CAPT MB]

My brake lights on the coach seem to have failed. I do get brake lights on my tow dolly when plugged into the seven pin connector so I know there is a signal leaving the brake pedal when pressed but the brake lights on the coach do not come on. All other lights (turn signal and running) in the rear work just fine. Thanks for any suggestions.

You need to check your fuses - should be in the same right side compartment as the start batteries. Check the bulbs and connectors at the tail lights as well. If you are still having problems, check the brake switch under the dash.

I had the lights go out on the towed vehicle for stop and turn signals. The compartment at the right rear of the coach had the fuses. I found that they had blown two fuses, but there are also fuses for the coach brake and turn lights in that same fuse block. I think they were the 30 amp style, very large yellow fuses. I went to the auto parts store and purchased a few extra just in case. Found the cause of the blown fuses to be a short in the cable from the MH to the towed vehicle. Some one on here pointed me in the right direction otherwise would never have found those fuses. Good luck

Wanted to update this.... The fuses in the passenger side rear bay all check out fine and I get a light at position 5 on the module (VMS 4 I think is what it is called) in that bay when the brake pedal is pushed. As stated originally, I have good brake lights from the seven pin connector to my tow dolly but none on the coach.
So, it would appear based on the dolly and module light that the signal is being sent when the pedal is pushed...
The chase continues....

Problem resolved. Worked with multiple Tiffen service reps and we concluded the issue had to be a wiring issue in the end cap. Pulled all plugs apart, cleaned and reseated them. Problem is now gone.
