TX....did you try my previous suggestion? Turn on the truck and move the seat as far up as it will go and then all the way back. If you attempt this it moves only a little?

Can anyone help me with my check engine light? I go into Alfa and it shows no fault codes found, but my check engine light continues to stay on.... is there a way to clear the light?

Are you connecting to the ecu and not the body Computer

Yea it is weird. For some reason the seat parameters are out of wack. It will move all the way forward to were the seat is about a inch from the dash and all the way back to were the seat is a little past B-Pillar. However, when moving in any direction is goes about half way then stops. I have to release the switch the depress it again to finish going forward.

Since I have a extra switch panel at the house I did swap the panel to verify it was not the switch. Both panels did the same thing.

You mentioned your seats will only move a little at a time. @STecoD's truck did the same thing when he didn't have the correct seat motors. Long story but he tried to add memory to the Sport seats but they didn't have the correct motors that relay the seat position to the Memory Seat Module so they would only move a littke at a time when he adjusted them manually. I'm sure you have the Laramie seats or you wouldn't have the memory button in the seat but it's possible you may have an issue with a seat motor. Does it do it in all adjustments like up,down,back,forward or just a certain movement? . When you did the seat standardization test? If the motors aren't sending and recieving information it will fail the test and not move. You could also try the MSM self test and see if anything comes up. I've done the seat standardization test before so I know it doesn't have any adverse affects. I haven't tried the MSM self test. Also did you check for DTC codes? Also not sure if it's been asked but does your easy exit seat work?

I currently have AlfaOBD that I used on my Chrysler 200 with good luck, and now have the 2019 Ram 1500 RCSB Classic and I was wondering why my window express doesn't work and everything I read on the internet says they don't have the feature only express down, can express up be programmed into it with my AlfaOBD?

Alright that explains the problem then... So I when I did the swap I was only given the wiring harness, heat/cool elements, panel, and memory modules. I did not think it would be a issue since my seat was already a 10-way non-memory seat. Long story short I caused my own problem, with luck I'm going to try to get the actual motor assemblies.

I was thinking it could possibly be something like that when you said the seat wouldn't move in any direction but you never mentioned you converted a standard seat so I kind of ruled it out. Your best bet is to just find a Laramie memory seat that has a blown airbag or is damaged in another way instead of trying to find all the individual memory seat motors.

I was lucky the individual with the donor seat gave me the seat back and I was able to swap the donor seat Laramie motors out for the non-memory 10-way motors. The seat and memory function now work perfectly.

Thanks everyone for the help...

I've read through a few hundred of these replies and haven't found it yet. Not going through 1100 plus. Is anyone using this on an 18 ram 1500 5.7L?? According to Talbot Industries and the manufacturer GDP, the bypass harness is not for it.
Has anyone here used the bypass harness on a 5.7L 1500? And did it work?

Starting with the '18 model year regardless of the engine you need a security gateway bypass to use AlfaOBD or any OBD software that attempts to write to any vehicle module.

Buy the one from here: https://www.kaodtech.com/
He is a forum vendor/sponsor.

Yes I have done some research and saw this but I have yet to see someone with the 2018 5.7 comment that they have used it.

Are you wondering if someone used the one you linked or just in general on a 18 1500? Most bypass harnesses you'll come by pertain to diesel bypass for tuners. A few are actually for the security module. I haven't come across anyone on this forum or cumminsforum that I'm on use anything besides kaotech.

Plenty of people have used kaotech bypass harness, I'd say 99.9% who have a 18+ used his. Plenty on a 18 1500 w/5.7 and eco diesel, I used it on my 18 2500 6.4L, plenty of people with 18 2500/3500 6.7L cummins have used it. It's been used on 2019 classic and 5th gens 1500 and 2500.

With the bypass only thing that matters is year and whether it's a 1500 or 2500/3500. Engine doesn’t matter. Alfaobd has choices for year/make/model(1500/2500/3500) then choices of what modules or computer's you want to connect to. 99% of the time you'll be in the body Computer. Rarely you'll have to do anything in the rf hub unless you are programming keys or have changed tire size (you'll need your 4 digit pin that the dealer should give you but if not for $15 you can use the Chrysler pin puller app. Plenty of people have used it), and rarely ever need to connect to the ecu unless you are checking for codes

Most questions asked in this thread are answered and explained if the very first(#1) post is read through. I've answered several people's questions by just copy-n-pasting info from the 1st post.

I have a 2018 and bought the bypass harness from the link above, and it works perfectly fine. Takes 5 minutes to install, plug in your OBD reader, fire up AlfaOBD and you're in business...

My knowledge in all of Alfa and RAM electronics pales in comparison to the people that contribute here on a regular basis. I am both thankful and amazed at the helpfulness and knowledge of those members. I do know a few things that will help those starting out with AlfaOBD.

1. Start by reading post #1 and if it's too much for you use the "search" function.
2. Follow this thread because there's something new almost daily.
3. Just buy the OBDlink MX because it's the one the developer recommends for his app.
4. 2018+ need a bypass harness and kaodtech.com (a vendor here) has the one for your application.

Hey everyone,

I finally got the MX interface and still waiting to go into town to get the Play card to get the AP. But I am playing around with the Demo to see if this cable I got will do the same as the Koadtech one (got it from nephew who ordered it by mistake). Before I got the MX, I could not connect to any of the modules or anything using a $9 interface I had laying around. Now it appears that I can do it. I was able to read the BCM config file and check for DTCs.

Now for the main reason of the post, while I was on my work break and checking out the stuff, I found some codes and appeared to be about the CHMSL. Of course I did not write them down, I will later today. The dealer put on a CHMSL light flasher prior to purchase and then I replace the bulbs with LEDs.

Going by whats below from the BMC log, it is strange to have "CHMSL Lamp Open Circuit DTC Enable: No" like that. I can only think that the flash module screws with the circuit and they turned it off.

Anyone know what "CHMSL Line CSM: No " does?

I searched the BCM file for "CHMSL" and these are the results. In () I took a s.w.a.g. and put down what I though the entry does.

I know it ****** to put this here without the actual codes, but wondering
1) if anyone with the dealer installed flasher/modulator thing has seen the DTC entry disabled
2) replaced using LED bulbs and changed atleast the LED present setting (I know there is a LED light assembly)
3) what is the CSM Is about
4) hoping this is a easy test of the cable to see if it will work (getting play giftcard today)

Your guess is most likely correct.....they were getting errors with it and basically "fixed the glitch" by disabling the error getting thrown. While not the worst thing ever, it is kinda a "lets sweep this one under the rug" approach.

The flash module most likely DOES mess with the circuit....the BCM probably sees the brake light flashing on and off as a bulb out, etc.

It MIGHT be able to be fixed by simply setting LED CHMSL Lamp Present to Yes....Im not sure anyone knows for sure, but we *think* setting to LED causes the BCM to ignore the current going to/from the light, if that is true then the flasher shouldnt cause an error anymore. I have LED bulbs in my third brake light and set LED present to Yes. No issues here, but they were bulbs that have "CAN adapters" built in to supposedly prevent errors. I do not have a third party flashing unit like you, though.

CSM = Customer Settings Menu. If enabled, it shows a settings menu on the radio (if applicable to your particular vehicle model). Im not sure what the Line CSM does.

TBH I wouyldnt be happy with a dealer installed module like that....I bet if you looked at the wiring its probably not the best. Maybe if they used factory-like connectors it wouldnt be so bad, but my guess is they just t-tapped off the existing wires.
