Ultimate OBD JScan Thread

[Julio13]

Can’t say that I have. Tried changing batteries or your other fob?

Yes same it must be the famous rf hub trying to get it replaced anyone replaced it themselves and used JScan to program it?

Where in Jscan do I enable remote start? I don't see it in the demo and wanted to verify before I buy it.

We have very extensive AlfaODB thread so I thought maybe it is time to start one for JScan? Seems JScan is slowly getting upgraded in what it can do and I am an Apple world guy so it is my only option right now. I don't mind buying an Android, but if I can use what I already have why not? I have found with the help of others that not everything works as you might think so a thread like this would help others get to where they need to be as members post their mod "recipe".

So far I have added auto high beams and fog lights on with high beam. Future mod is adding passive entry (parts are on the way) and programming a new key fob to allow for keyless tailgate open.

Here is how I activated fog light with high beams and auto high beams.

Fog lights on with high beam
Adaption>VehicleUserSettings>Front Fog Lamp Dropout=active switched to deactived
Set auto high beam option in radio
Search for "auto" in app
Auto High Beam CSM on/off>switch deactivated to active then restart ecu

Auto high beam
Choose Jeep Gladiator JT as the vehicle. Then go to adaptation, then auto headlamp & auto highbeams settings:
Auto High Beam CSM On/Off- ACTIVE
Auto High Beam Module Location- IRCM
Auto High Beam On/Off- ACTIVE

I’m sure I’ll find out on my own when trying this but I assume we don’t have to use AUTO high beams to make/deactivate fog light dropout when turning on high beams? Because I can’t stand auto high beams. They turn on and off at the wrong times in many cases. Thanks

Definitely not

Made a variety of changes: steering wheelheater from just on/off to high, med,low ,off, then fog light dropout with high beams, brake light alt blinking with turn signal.
Waited about 15-20 minutes started up and did not see the heated steering wheel change. Didn’t check the others.
I figured it didn’t take but after reconnecting the red by pass cable an Bluetooth adapter, opening up JSCAN again I could see the changes I made WERE in there. My assumption is I didn’t wait long enough for the computer to shut off. So I’ll give it a good 30 minutes to an hour this time. Any other, quicker way to see these changes?

Depending on the app version on your display, it may not work. I used to have it enabled on my truck, and according to alfaObd, it still is, but since updating to latest app version, I lost the three level heated steering wheel. Pretty sure my tailgate open indication is also gone.

 

[vtcats]

Good to know. I also turned off the seat belt alarm. Hopefully SOMETHING I’ve done actually works. Guess we may need a new or another updated JSCAN thread of what now does NOT work. @Jimmy07 can you confirm any of this as well?
I do have a start stop eliminator but that works because I have it always plugged into the 12 pin connector. Except when I had to plug into the dongle for JSCAN that is.

 

[vtcats]

I can confirm the fog lights stay on with my high beams but as mentioned the steering wheel change did not work and not sure about the break light alternating blinking with turn signal. Having said that, I got this error from my radio (see attached image). I was able to hit okay and it went away but it pops up every start. Not sure WHICH of the 4 changes I made cause it.
1) steering wheel or 2) fog light drop out or 3) alternating brake lights with turn signal or 4) seat belt alarm off
Any thoughts?

 

[vtcats]

I guess I’m basically talking to myself here but maybe someone will have this in the future and will follow along. After lots if internet research there is only one (maybe 2) solutions that makes sense (to solve my error of “SOS call unavailable”.
People who,have had this issue with Ram/Dodge etc fixed by disconnecting the negative battery terminal an hour or so. It solved it but most had stuff disappear that took a day or so to reappear.
BUT, this issue FOR ME, only happened after my second exercise of disconnecting the 8 and 12 pin connectors to make changes with JSCAN. While it’s possible it was one of the changes I made, I don’t think so. Someone else found that this error appeared due to a poor pin connection. They reseated the connector and the problem went away. I’ll verify tomorrow but this makes the most sense to me given how difficult it is to get to those 8 and 12 pin spots in the truck. Unplugging and plugging in multiple times. There’s a very good chance it’s loose and not tight enough or clicked in.
I’ll report back tomorrow, we will see

FYI, You can always revert each change you made one at a time in Jscan to see which one caused an issues.

Or back out all four and verify error is gone, then add changes in one at a time.

 

[vtcats]

Can confirm, I just didn’t have the 12 pin connector seated all the way in. Problem solved!
Having said that, afterwards, I did cycle the radio twice just to see if my steering wheel heater options would be added per the changes with JSCAN and the answer was no. I’m assuming HSKR R/T was correct in that the app version of the display has changed since this was first done rendering this mute. Maybe @Jimmy07 can confirm?

@vtcats Can you share what settings you changed for the steering wheel modes and the brake light alt blinking?

 

[vtcats]

For the steering wheel, it was Modules, Body Controller, Configuration, then just select the heated steering wheel levels.
For the brake light alt blinking (which may even work I just haven’t been able to tell while in the truck just yet), was Adaption, Lights conversion US-EURO, separated lighting brake/stop lamp dropout -on/off, deactivated.

Do steering wheel show you visuals for different heat settings? if not, how do you know which setting its on?

Same as the heated seats. Except those show 3 heat settings. The wheel just one. When you tap it, it lights up for on, then tap again for off. In JSCAN you can select on/off which is the default or high, medium , low, off.
As other posters have said, it was something that USED to be able to be changed but the latest app version on the display seemed to render this back to only on/off.

I see the setting there in demo mode:
Choose Ram 2019-2024 DT > Modules > Body Controller > Configuration > search “seats a”

Q re: JSCAN & Bigger Tires: TCU / Shift Point Adjustments. Newbie here. Have been using the OBDLink MX+ bluetooth scanner with the bypass cable in my 2022 Ram Rebel 1500 ecodiesel & the native OBDLink app for about a year-- the driver for choosing the MX+ was / is it appears the fastest in communicating real-time data. Only have iOS devices, and don't want to buy a separate burner Android for the sole purpose of using the AlphaOBD app. Recently changed out tires from the Rebel's OEM 275/70r/18s Duratracs to a 285/75/18 KO3. I don't much care about recalibration for speedo / odometer reasons (running Waze on the OEM 12" provides the actual speed via its embedded GPS) & even if I don't have Waze or a GPS-based speed app running, the math is pretty straightforward to do in your head re: what your actual speed is vs. what the speedo says. HOWEVER, with my now-heavier & taller tires, the transmission shift points are 'off' and it should probably hold gears just a tad longer for smoother driving & to mitigate the now-increased lugging tendencies. I've been thru this entire thread and, while awesome re: JSCAN appearing to be catching up to AlphaOBD.... can't seem to find detailed instructions for recalibration of the TCU / adjusting of shift points for larger tires. I saw some mention that one can do this with JSCAN, but haven't found much detail or a color-by-numbers video on how to do this with JSCAN. Again, I'm a noob & haven't yet installed the JSCAN app so apologies in advance for the no-doubt already-existing thread treating this exact Q. But as you appear to be the resident expert on all matters 5th Gen Ram & JSCAN, TIA for pointing me to such already-existing thread and/or YouTube video going thru the reprogramming of the TCU / shift point adjustment for larger tires. TIA, kind sir!

If you unplug the battery for some time, this will reset trans to the factory settings and it should re-learn in time.

There is no transmission shift point adjustment. It is done by correcting the speedometer for the bigger tires by adjusting for the taller tires. Make sure that if you’re using a gps app on your phone to check speed, the phone can’t be connected to the truck in any way (otherwise it’s using the truck’s gps and relaying the incorrect speed to your phone app).
