Yes, our exhaust brake will activate the brake lights. I noticed it when I was driving in the wee hours of the morning and used the exhaust brake going down a good decline. The Honda lit up like a christmas tree! So, now I know.

Roy....Some do, some don't. My 2005 Diplomat was suppose to, but somewhere the wiring connection is missing. I took it back to Monaco twice and they couldn't find what was wrong. It made me mad because I was trying to add the "Brake Switch" aftermarket accessory to mine which allows you to activate the exhaust brake by tapping the brake vs using the switch. It also lets you use the cruise control while the exhaust brake switch is on. The newer coaches do this automatically.
CAT can do that, but it costs $200+ just for PC programming time. Grrrrr

The re-programming of the engine ECM charge for changing a Caterpillar engine to "LATCH" mode is up to the dealer. $200 sounds excessive and more than most have reported.

In LATCH mode, exhaust brake comes on when you are off the throttle and apply the service brake (even lightly). It then stays on (whether you stay on the service brake OR MORE IMPORTANTLY, TAKE YOU FOOT OFF THE SERVICE BRAKE until you apply throttle.

A very good choice, IMO. It allows for full time exhaust brake for any emergency stop, but also allows my favorite "gear" coasting!

Does the brake light come on when the exhaust brake is activated
Thanks Roy


Depends on the year ( model year) of the coach. My 2000 does not but I think the 2003 CC's do..as an example

Some chassis makers DO tie in brake lights with the exhaust brake, other do not. Good reason for either choice.
