Turbo Failure

[Wiredawg]

It's probably another safety nanny, afraid someone will jump in, forget their EB is on and play slip n slide the first time they let off the go pedal. Forcing someone to engage it Everytime takes the liability off of Ram.

That's what I think too. I guess they think the cml drivers who predominately drive C&Cs are better trained or something. I like it.

Cliffman,

Always run with it on (except icy, slippery) to keep from building up carbon and reduce wear on brakes.

Cheers, Ron

And does the Tow/Haul mode also help with that?

I dont run TH except when towing because with 4.88s, it WAY too aggressive for me. Others have posted they run it all the time with 3.42s and 4.10s. Running TH all the time might boil down to be more of a personal preference thing as you might could also call TH Sport Mode. Just too SPORTY for me.

Cheers, Ron

I run T/H all the time when I have the Camper in the truck. I like the slightly higher shift points and more aggressive EB when I'm at 14K. Unloaded I run normal mode as I like the earlier shifts because it gives better fuel mileage but I do miss the more aggressive EB action though.

If I don’t use the Tow/ Haul my engine brake never turns on. But using the Tow/Haul does lower my MPG’s a bit. Price to pay... But I agree why can’t the truck stay in what ever setting you leave it in. Very annoying to have to reset it each and every restart.

TH-EB all the time!!!

That's interesting your EB doesn't function turned on unless TH selected, I had not heard of that condition before.

On my MY 2017, it has Smart Brake mode on EB that states it's more for maintaining speed than decelerating, but I haven't cared for using it.. Not sure if this thread will necessarily catch attention of folks with that feature to comment on it. I might just start a thread asking folks for their opinion and experience of Smart Brake mode of EB.

I may have something to do with were you live. On my 18 when you are not in TH the EB will drop out at about 42mph. In Phoenix were our speed limits are 45 and most people drive 50-55 on city streets it works fine. When I visit places where speed limits are only 35 (or less) it almost never kicks in.

Tied it a couple times and didn't like it. Didn't give much braking and the Cruise would do that same thing if the brake was in full on mode.

Not sure what everyone else's FOM says, but here is what my 2017 manual says about it:

DIESEL EXHAUST BRAKE (ENGINE BRAKING) The purpose of the exhaust brake (engine braking) feature is to supply negative (braking) torque from the engine. Typically, the engine braking is used for, but not limited to, vehicle towing applications where vehicle braking can be achieved by the internal engine power, thereby sparing the mechanical brakes of the vehicle. Benefits of the exhaust brake are: • Vehicle driving control. • Reduced brake fade. • Longer brake life. • Faster cab warm-up. The exhaust brake feature will only function when the driver toggles it on by pushing the exhaust brake button until the Exhaust Brake Indicator is illuminated. Normal (Full Strength) exhaust brake mode is indicated by a yellow Exhaust Brake Indicator. Once the Exhaust Brake Indicator” is illuminated and the vehicle is moving faster than 5 mph (8 km/h); the exhaust brake will automatically operate when the driver removes pressure from the accelerator pedal. Exhaust braking is most effective when the engine RPM is higher. The automatic transmission will downshift more aggressively in TOW/HAUL mode when the exhaust brake is enabled to increase brake performance.

CAUTION! Use of aftermarket exhaust brakes is not recommended and could lead to engine damage WARNING! Do not use the exhaust brake feature when driving in icy or slippery conditions as the increased engine braking can cause the rear wheels to slide and the vehicle to swing around with the possible loss of vehicle control, which may cause an accident possibly resulting in personal injury or death.

NOTE: For optimum braking power it is recommended to use the exhaust brake while in TOW/HAUL mode. The exhaust brake feature can also be used to reduce the engine warm up time. To use the exhaust brake as a warm-up device, the vehicle must be stopped or moving less than 5 mph (8 km/h), the Exhaust Brake Indicator must be on, and the coolant temperature must be below 180°F (82°C) and ambient temperature below 60°F (16°C).

Automatic Smart Exhaust Brake (Auto) Automatic Exhaust Brake technology delivers smoother, less aggressive exhaust braking characteristics during downhill descents. Although it can apply full exhaust braking force if needed, Automatic Exhaust Brake may not apply obvious braking if the vehicle speed is not increasing. Automatic Exhaust Brake is intended to maintain vehicle speed, while Full Exhaust Brake is intended to reduce vehicle speed. Automatic Exhaust Brake can be enabled by pushing the exhaust brake button again anytime after the normal Full Exhaust Brake has been turned on. The “Exhaust Brake Indicator” in the instrument cluster display will change from Yellow to Green when Automatic Exhaust Brake is enabled. Pushing the exhaust brake button again will toggle the exhaust brake mode to off.
​

This pretty much describes how mine works.

Ron, are you saying C&C automagically qualifies one for a better memory? That's it, I need to run out and buy one
Lord knows I could use sum help in that department

Buy two, in case you forget where you put the first one

Can I like this comment twice just in case I forget about the first one?

Some do that already, why shouldn’t you get in on that?

It’s too aggressive for me and my 3.42’s when empty most the time. I will occasionally use it, sometimes as a sport mode.. sometimes because of traffic and such. I guess less than 5% of my empty miles have been TH on.

 

[SnoKing]

Empty I turn TH on when on a freeway off ramp that is steep. EB all the time.

 

[EDankievitch]

The engine brake will work until the engine RPM goes below 1100. When not in tow haul my truck unless driving over 50 is right at 1100rpm. So the brake never comes on. In tow haul the transmission will down shift and keep the Tq converter locked up. The engine brake works awesome. In ether on or smart brake modes. I like the smart mode as the brake will not come on until I hit the brake peddle and turn on the brake lights. In just on it comes on as soon as you let off the throttle. Scares the hell out of the guy tailgating you.

Anyone that tows and plugs in the 7 way harness from the trailer may have noticed that upon restart, the EB automatically stays on if it was turned on previously. I read a few years back that someone had purchased a replacement 7 way connector and made a jumper connecting (I think), the brake lug and ground insude tge dummy connector. The dummy 7 way is inserted into the power port in the bed of the truck. This fools the truck into thinking there’s a trailer attached and will allow the Tow/haul and EB settings to remain on at each start up.

 

[JR]

Only the EB function returns with a trailer plugged in. Tow/haul still off with or without trailer. At least that's how my 14 is.

Mine will randomly remember, but 99% of the time does not.
