Thanks, TDR Staff

Today is the day my 2019 3500 custom ordered truck arrives!!!

New 8th Gear transmission in 2021?

While driving on Friday, towing my travel trailer, I looked down and my selectable gauges (oil pressure and boost) had been replaced with a gauge that had the glow plug icon under it and a yellow bar graph that had one segment lit. There were no messages and no warnings attributable to this gauge. I have previously and occasionally noticed that the selected satellite radio channel will have changed when I start the truck. I stopped and went into instrument panel settings and checked the selectable gauge settings. They were still indicating oil pressure and boost, but I changed them to something else and then changed them back but the display remained the one glow plug gauge.

I then killed the engine and re-started it and the display returned to normal showing oil pressure and boost.


What is going one? What is that gauge? I can't find it listed in the manual or diesel supplement.
 
Well thats weird....gremlins still hanging out after Halloween, just messing with your truck. This will be interesting to follow. Hope you find out the cause.....that would drive me nuts.
 
No Dodge/Ram/Cummins has ever had glow plugs. They have grid heaters which is in the intake instead of the combustion chamber.
 
Sounds like a glitch with the dash. The WTS light also has a timer on the lower selectable gauge, but that’s only supposed to be before you start the engine. You cannot select it or turn it off, but you can bypass it by starting the motor before it’s complete.


FWIW: oil pressure is a waste of a gauge, it’s fake...and there is already a permanent fake oil pressure gauge on the dash.
 
There are no glow plugs in 3rd or 4th gens. Maybe it was cool enough for the grid heater ?
Interesting. I didn't know that. The icon below the gauge was a multi-turn col, which I have previously seen used for glow plugs. I don't recall seeing an option for the grid heater as a gauge in the selectable gauge list, but I may have missed it. Outside air was 55 degrees F. Should it have needed the heater then?

Signal73 is correct no ram/cummins has ever had a glow plug. Thanks for that clarification.

I think below 60 F the system will pause for a few seconds of grid heat.
 
Forget about that WTS Light, just jump into the truck and crank it over, that's just fine and it safes your batterys from that horrible drain at every start.
I'm pretty sure that's the main reason why do many batterys in these trucks fail prematurely.

It's for Emissions only, the ISB starts fine without it far below of freezing temperatures.
 
Historically if the intake manifold temp is below 66° the grid heaters will operate. I haven’t checked the tables on my 18 yet.

Thats very possible on the battery drain, although I got 5 years ,and 8 months out of my OE's. Yet my son got just over 2 years out of his on his 2016. His truck gets used every day, mine does not .

I have the push button start, and it does its thing, if it needs the grid heater I just have to wait. There is not a setting I have seen that I can bypass my grid heater. My old Superduty I could just fire it up with the key, no waiting for the wait to start light to go off . I'm not sure where the temperature range is, but it doesn't seem to have to be very cold on this Ram for the grid heater to activate.

What I heard from others is, just push the button twice and it starts up immediately.
Tried that?

Ozy
 
Regardless of temp, there is no reason for the "wait to start" indicator to come on while driving. I don't know what the limits are for the grid heater to come on but I've seen it in the high 50's when the truck is cold.
