2008 Winnebago Journey 37H

Thanks for the input. I suspected it was operating correctly until I drove the second one. On both I could tell the exhaust brake was working but the second one I drove did not have a light on the dash to come on. they were identical Journeys same year engine. Two different dealers. Thanks again.

The VGT Exhaust Brake is working as designed. I leave mine on all the time, seldom need to use the foundation brakes for normal stopping or slowing down.

If the 'exhaust brake' switch on the dash is in the 'on' position, the exhaust brake will engage (and green dash light with come on) whenever you lift your foot from the throttle pedal.

If you turn the exhaust brake light switch to the off position, the exhaust brake will not engage when you let off the throttle. That is generally how Freightliner set them up.

I had a 2002 Journey with CAT engine and hated the way the exhaust brake worked. I installed a device called a 'Brake Switch' that would allow me to leave the dash switch 'On' but the exhaust brake would not engage unless you actually pressed the brake pedal.

? Anybody know the answer?????

I suspected it was just a dash indicator light to let you know it was on. When coming to a stop the light went out. Then I drove the second one and it didnt come on at all. this may be on all Cummins 6.7 this will be my first one. Thanks in advance for your input if something is wrong I like to know before I buy.
