Factory remote start not working after tune / delete - truck shows no stored DTC codes

I've searched almost every post I could find on here and I can't seem to find a similar post with my situation and if this is in the wrong section my apologies. Before tuning the truck the remote start worked fine as it should. Now, as the title says, it doesn't work. When attempting to do the remote start the truck lights flash (I turned off the horn from beeping in uconnect) and it seems to want to go through with the remote start but it just sits there and the dash displays "Remote Start Active Press Start" (wording might be off but this is pretty close to what it says). Additionally, I don't see anything that stands out why the truck wouldn't want to start.

Is there anyone with factory remote start for a 2017 (or just somewhat close to this year) that can tell me what is normally seen on the dash when doing a remote start that is tuned as well or that just has factory remote start without the truck being tuned? I unfortunately never paid attention to what it said if anything when it was stock because I really unfortunately did not think that tuning would potentially cause this to not work but here I am. I've asked my tuner a few times what to check and the best answer I get is check for codes which I understand if there any codes it will stop the remote start from working but as stated in the title unfortunately there are no codes and none stored that I can see with a snap-on scanner.

Hoping someone on here has some wisdom they can share with me so I am able to regain the remote start functionality.

Thanks,
JT21

Mine doesn't give me a problem. I know you don't wanna hear that but..... So all I can do is guess at this point.

Maybe a couple of hints that could help, re-set your UConnect back to stock. If that doesn't work, re-flash the tune. I always try to fix something with the easiest and cheapest thing possible.

It's not that I don't want to hear you have a working truck that's fine to know this, glad to hear people with tuned / deleted trucks are actually having functioning remote start systems in their trucks. This is hopeful as I am out of ideas. Thanks for responding, appreciate it.

There's a reset option for Uconnect? My knowledge is limited of how tuning works, there's actually a chance that the tune could not be flashed properly but the truck will run? Is that really a thing? Only reason I am questioning on re-flashing is I would expect other issues to occur (what those other issues are I have no idea)? But again, I'll go back to my limited knowledge on this whole thing.

Trust me I want to find the cheapest option first before I start spending more money on something I've already sunk quite a bit of money into the truck already getting it to this point.

I have factory remote start and not tuned and I can see what the message is at lunch when starting it. I know if the remote start is cancelled due to CEL, low fuel, door opened, it'll say that in the EVIC.

Perfect, thank you! All the things you listed unfortunately I've gone through thanks for listing them again though I've double and triple checked those things. My neighbors think I'm crazy by now I can bet you money on that. My EVIC is clear when I go to remote start it and nothing on there shows anything stating what's cancelling it unfortunately. I've looked at my dash more than I care to admit hoping that something will just pop up and I can do the "Ah ha" moment then fix that whatever is causing it and it'll work. Sadly, not the case for me. It has to be my luck.

I don't vouch for the accuracy of this link but I do know there's a reset function. If you're still connected with UConnect, you can always call them.

 
#10 ·
Thanks for the info, I am curious what exactly a factory reset will do. I understand to a certain degree it will change my settings and everything back to way the truck rolled off the line but will it remove any other features or functions that were possibly programmed after maybe at the dealership (this is a used truck I bought and as far as I know I'm the second owner). I'll do a bit more digging before attempting a factory reset for the Uconnect. Just don't want to start doing all of this if there was something that happened to be in plain sight that my eyes couldn't see somehow. That's my hope and prayer anyways.

Thanks so much for you guys with responses so far, really appreciate it.

JT21, sorry not to contribute to answering your question, but i am curious do you have Vented seats? I am tuned with EFI as well and my vented seats buttons in my UConnect unit are greyed and do not work the physical buttons beneath the unit do work still work just not through the head unit. My remote start works just fine.
 
#18 ·
No worries, I have vented seats. To be quite honest I'll have to check. I know the physical buttons below the Uconnect do work as I seem to always use the physical push buttons below and not really the uconnect screen (strange probably I know). I can get out in the truck later today and give it a shot to see if my seats work using the Uconnect head unit or not. And damn it that your remote start works and mine doesn't lol.

There has to be something I am missing here but I'm stumped.
 
#22 ·
Something simple to try. Mine is a 2015, not sure if yours is different. BUT, it was installed by the dealer after my truck came in, they had to program it to tell the truck it had it. They said it was all plug and play, except for a ( hood latch switch) that they installed. Try to find the switch and clean and test it for the heck of it. The switch is there so if the hood is up and your working in there, no one can auto start it.
Mine worked fine before and after my delete and does start with a cel, but as others, shuts off.
 
#25 ·
Not to be rude but if it was the hood latch switch, wouldn't my dash state the hood is opened? I appreciate the response in help and I've seen other's say hood latch could cause the issue on other places but (from my research and I have not read everywhere on the internet) these people with the issue have the "hood open" message. I am sure anything is possible but would our trucks not tell us the hood is open if the latch has a problem? I'll need my truck for the next few days or more depending on travel needs and I'll check on the hood latch when I have down time to tinker, I'll make sure to add it to the list so I can do the old "check off the list" kind of thing.

For all I know maybe it was bumped just enough where it won't throw a warning on the dash but it stops the remote start? Just throwing out a crazy idea who knows... stuff like this could be something but it seems like I'm going down a rabbit hole and I may never return lol.

Does it just not work with the uconnect or not with the remote as well? Try unhooking both batteries neg terminals for a hour or overnight and then see if that resets it. With the snap on scanner scan everything and then clear everything even if there is no codes showing. Who is the tune from?
 
#26 ·
I hope this was for ZMiller, I don't have a problem with Uconnect, sorry. The batteries were unhooked when my truck went to Mexico, I need to get in touch with the ole mechanic who did all the work and see how I can get this further diagnosed. I'm not ready to go back to the tuner and point the finger at him just yet. I'm trying my best to rule out everything possible before I start down that path. My tune is from Optimal Welding. I started this thread separate from the big thread that is going on because I felt like maybe it could be something simple that I just missed and someone else who was tuned may have been able to just say "plug this back in" etc... but now it seems like that's not the case lol.

Overall I'm just glad my truck runs and I can drive it - could be worse but the remote start is a nice feature to have and at some point I'll figure it out when I get more time to tinker with the truck. I'll give the battery reset a try as well.
 
#29 ·
I thought I posted this in my original post but in case I forgot to, I used a snap-on scanner. I realized quickly that my little edge CTS2 probably wouldn't get all the codes since I believe that sometimes there are hidden codes that don't cause the CEL to come on. Now I'm in a waiting state at this point since I need to use my truck for the next few days and what not so tinkering is something I don't want to do with at any point since the remote start not working is just a minor inconvenience and the truck starts / runs fine if I just get myself into the truck and start it. I also need to wait until I get my mechanic to give me some more of his time to check out maybe the hood latch or resetting the RFH.
 
#32 ·
I got a problem with that, I somehow didn't read my stock tune (yes, my fault) I thought I did this all prior to tuning but did not double check my autocal and well no stock tune. I also, um ditched the parts that came off the truck, told the mechanic to get rid of it since I didn't think I'd be attempting to go back to stock. So, yep, here I am. Probably learned a lesson here is to not throw crap away until I'm sure I don't need it anymore and... do a double / triple check on my autocal for the stock tune file.
 
#33 ·
Question, just because I'm curious if this would work at all is.. if I had by chance got the stock tune saved and was able to tune it back stock, would the truck even start with all the stuff missing? I was under the impression that the truck wouldn't start because of all the stuff gone? I'm a newbie to this newer truck stuff... last truck I owned was an 06 5.9 and that thing was so much easier but I was greedy and wanted the creature comforts of a newer truck.
 
#36 ·
JT21, does your truck have Uconnect 8.4? I have been doing some reading on other forums and i am starting to think you may have an issue with Uconnect and your remote start system. Uconnect is connected to the remote start system being able to start the truck through the phone app. So i am wondering if its glitched and you need to perform a reset on the Uconnect. Only way i have found to do a reset is to disconnect the negative batt. cables. The directions for a soft reset do not work on my unit. It might be worth a shot to disconnect the cables and maybe your remote start will come back.
 
#37 ·
I am not sure what version of Uconnect my truck has, I'll have to check. Also, does it pertain to certain versions that you've read on other forums? Appreciate the response on this and insight but what leads you to believe that my issue has to do with Uconnect? The reason I ask is because I don't use the phone app at all and I was under the impression that the phone app was the problem with remote start potentially not working after tuning. As in somehow the system got all weirded out because of the app? Don't get me wrong anything is possible now-a-days with all this new crap in the trucks and technology they have, I love all the neat new features of this truck but miss the simplicity of my old 06 5.9 truck.
 
#38 ·
I was thinking it had to do with Uconnect because there is a part of the Uconnect system that connects to your remote start system. And i was just wondering if maybe that part of the system is glitched and not allowing the truck to start with your key fob. i am just trying to throw ideas out there and i know that the Uconnect system is tied in to the remote start system.
 
#39 ·
I appreciate all the ideas and responses, honestly I do. I'm just frustrated at this point going back and forth and repeat the process of "that can't be it" or "I've never seen that before" from the mechanic and the tuner. Since you know the uconnect unit is tied into the remote start system is there anywhere documentation wise that you know of that states this specifically?

I tried my hardest to see if the tuner would tell me anything about the uconnect or infotainment stuff being connected to the remote start and the response I got back was something along the lines of that he only does the performance side of the trucks and nothing with the entertainment / infotainment stuff - these are separate systems from the performance side of the truck. Again, that's from the tuner.
 
#40 ·
just read this i know your not getting the hood open message but maybe OHM it out with a meter?
 
#41 ·
Did you have any CEL codes or warning messages of any kind before deleting? Emission issues etc? I know some tuners will disable faults so you don't see them pop up but if it was there before it may have just been masked so you can't see it which may prevent it from remote starting? Just a thought.

#42 ·
Thanks for the reply, no CELs or warning messages of any kind before deleting. Used a snap-on scanner and everything was good before the deleting and tuning occurred. I was just told by the tuner that he doesn't know what it is causing the issue and that he only deals with the performance side of the trucks, nothing to do with the infotainment stuff or alike. Basically, I believe the tuner is just washing his hands of everything that I've attempted to ask on this whole thing.

I wish I could find a local tuner that I could actually drive to and get tunes from so if issues like this came up, I could go over there and show him and get it further diagnosed in person. This remote tuning stuff is great when everything works but creates a bit of a problem when things don't go as planned.
 
#44 ·
I'm not going to have time to diagnose this further for a while - need to tend to life itself overall. Thanks for everyone's replies / comments and suggestions. Once I get time back, I'll get to testing everything mentioned in this thread. Or by some luck chance it actually starts working just because magic I'll report back and let you guys know what finally solved it. I'd like to have this sucker solved before winter just because I'm lazy and rather click a button instead of walk outside to start the truck. I'm half tempted to find another tuner but really reluctant to shell out more cash... I feel like I'm in a stuck situation here lol. Oh well, life goes on and at least the truck starts and drives.

I saw you posting on the other thread in the performance section but wanted to keep the remote talk here.

Are you familiar with the AlfaOBD program at all? It would give you the ability to look at (and change) your BCM settings. It might give you a little more insight as to whether it is still enabled?

For instance in my BCM log I can see these flags are set to "yes" Yours are no or corrupt now? I'm still leaning towards a CEL though

ECU Qualification:
.....
Adjustable Pedals Present (Non-memory): No
Inverter Present: Yes
Intrusion System Present: Yes
Remote Start Present: Yes
Tip Start Present: Yes

......
Vehicle Configuration set in the Body Computer:
Vehicle Config 1:
Model Year: 2016
Vehicle Line: DJ
Country Code: USA
Left/Right Hand Drive: Left Hand Drive
Remote Start Present: Set

If not I'm still thinking there is a CEL or fault that is being hidden by the tune. Did you use Optimal for tunes? He tunes a little different then others do it appears and I have seen comments on his site about "No derates or shutdowns enabled. Truck will never leave you stranded or limit your speed for any reason" so it makes me think he is disabling or hiding a lot of faults with the way he tunes?

Unfortunately, without the ability to go back to a stock tune there is no good way to rule out the tune?

I am not familiar with AlfaOBD. I could check it out, I suppose a roughly $50 investment might be worth it, instead of possibly spending another something amount to get tunes from another company / person just to rule out his tunes being the issue. I wish there was an easier way to do this rather than tinkering with the truck with doing certain checks when it was all stock it worked fine (I know it's the same old crap right, worked fine stock, broken tuned)

Yeah going back to stock may not even work, I'm almost 99% sure of it. If I were to get my stock tune and flash it onto the truck, since some of the parts are missing, it will definitely throw a CEL, wanna know how I know? Before tuning it, I tried the remote start with all the stuff that hit the bump and the weight loss procedure was done. Truck wouldn't start - figured after tuning it would. I shouldn't assume I guess.

If it was a CEL or hidden DTC, my mechanic would see it on his snap-on scanner wouldn't he? He showed me himself (because I was curious and asked) that the DTC and areas he was able to check for hidden codes was clean. Since I'm not mechanic myself, I can't really go against what I was shown and refute to some degree that he is wrong.

I'll give the AlfaOBD program a better look, thanks for the info on this.

There is a huge thread on another forum about AlfaOBD. It can make changes to the BCM, add options etc. It's extremely handy and has a ton of support for Ram trucks. I would say it is probably used more on Ram then anything right now. Say your tradesman didn't come with remote start, you could add it with Alfa and set those flags to yes. You can change your TPMS settings, program new keys and on and on.

I'm assuming you went with optimal since you did not answer? I'm only saying that because it did not start with the stuff still on. That goes back to him tuning different then others and maybe why yours is screwed up. With his tunes you have to have everything disconnected before starting or it could cause problems (from what I have read). Other tuners are not that way. Most other tuners you can start your truck with everything still attached to make sure all was good before removing stuff.

As far has "hiding" the CEL or DTC's I have no idea if a snap on could see it? If it was coded out of the ECM maybe not? I don't have an honest answer because I just don't know. It is obvious that something is preventing it from starting and what ever it is isn't showing up?

UPDATE, since I created this thread I thought it would be appropriate to at least provide an update and resolution to my issue here.

After going back and forth and trying to prove to Optimal Welding that his tunes unfortunately removed my remote start and him telling me it was my truck, I reflashed my truck exactly once. No dice didn't work. After attempting to contacting him further on the wrong base file that was sent for my truck he never responded back. So, I had to move to another tuner and I did.

After my very first flash and only flash, remote start works, no issues. No CELs either at all and all my features and functions work just as expected, everything.

For MPGs, no idea as I haven't had time to drive it just yet but I'll report back here as well if I find anything that stands out as far as MPGs.

Unfortunately, I had to go this route... and sadly had to spend more money. But seeing as though I was getting no help on my issue past being told it was my truck, I had no other choice I believe and just move on.

To clarify, this not meant to throw shade at Mat and his tuning, the performance for my truck was good, just the support I believe from him was a bit more lack luster than I expected. If you're one of the lucky ones where your truck has zero issues from his tuning, great for you and I am happy. I was just not fortunate to experience the same for my truck.
