Question for you smart people about MDS

<div class="bbWrapper">2025 2500 hemi here.... you definatley have them. As other have said they are on your steering wheel and they are the +/- sign and look like this. <br /> <a href="https://hdrams.com/forum/attachments/1758579403374-png.89837/" target="_blank"><img src="https://hdrams.com/forum/data/attachments/89/89845-f8d5c1b92f7427dcdc6b20e67d714730.jpg?hash=WHDQYr-LPD" class="bbImage " style="" alt="1758579403374.png" title="1758579403374.png" width="228" height="150" loading="lazy" /></a><br /> <br /> When turning it on, push the + sign till you get to the number 8 (for 8th gear max) and the gears will display on your cluster,. Once you see it, it means your gear selector is activated and your MDS is Deactivated. <br /> <br /> If your driving and forget, just push the up sign once and it will display whatever gear you are currently in, however be sure to push + again until you hit 8. Otherwise whatever gear is displayed it will not pass that.</div>

Never had a single issue with it in 5 years i had my 2019. Far and away the best implementation of any start/stop tech I&#039;ve had the (dis)pleasure of using, and a huge part of that was not using a conventional starter. Would have been fine if my 2500 came w/ eTQ (though I wouldn&#039;t have wanted to add another $2500 to the price or whatever). </div> <div class="bbCodeBlock-expandLink js-expandLink"><a role="button" tabindex="0">Click to expand...</a></div> </div> </blockquote>In my opinion, yes. When I decided on a 1500, two things I didn&#039;t want to live with, e-torq and a 12&quot; screen. I liked my 2021 1500 5.7, I just prefer towing with the 2500.</div>

I’ve never seen that, just the ECO light disappearing and the truck suddenly running as it should. <br /> <br /> <br /> Sent from me</div>

Ive never seen or heard a message that tells you its deactivated.</div>
 
<div class="bbWrapper">I think I&#039;ve seen message of some sort myself. I will try and get a picture of it.</div>

<div class="bbWrapper">I can take a picture tomorrow morning for all of you. I&#039;ll be honest it appears quickly and then goes off so it may be a blurry pic.</div>
 
<div class="bbWrapper">FWIW, and not to re-start a new MDS discussion, but ... don&#039;t disable it all the time. It&#039;s a mechanism that is meant to operate, AFAIK there aren&#039;t too many MDS failures on 6.4&#039;s if well maintained meaning oil changed on schedule. There is some evidence that disabling MDS all the time can cause it to fail sooner. I tend to disable it for local driving when I don&#039;t want it jumping in and out of eco mode, but for much/most of my distance driving I leave it enabled. The little added vibration doesn&#039;t bother me and I figure I better keep the mechanism operating regularly.</div>
 
<div class="bbWrapper">Here&#039;s a picture of the message in the evic when you diesel the MDS. <a href="https://hdrams.com/forum/attachments/20250924_122052-jpg.89861/" target="_blank"><img src="https://hdrams.com/forum/data/attachments/89/89869-1978df629c2c70e2e1147462cc431299.jpg?hash=pBoLwByU7X" class="bbImage " style="" alt="20250924_122052.jpg" title="20250924_122052.jpg" width="200" height="150" loading="lazy" /></a></div>

Thats telling you the ERS mode is engaged (ERS = Electronic Range Selection, exactly what it sounds like, your selecting your gear range.) However once gear is selected its deactivated. Theres no message and you want &quot;know&quot;, in other words it wont be displayed., however as we have all stated....it DOES deactivate MDS. <br /> <br /> Also.... Tow/Haul mode deactivates it as well I believe.</div>

Its the same as a 1500 with those 2 options.</div>
