Alfa OBD issues

[infectious208]

Ok guys, I think I made a boo boo.

I recently installed a 2018+ radio in my 2015 ram 2500 for android auto capability. Everything worked great except for the soft touch buttons for the heated and vented seats and the heated wheel.

I recently installed Alfa obd as I read there may be a setting "cabin net - heated seat module" that may need to be turned on to get them to work.

I was able to find the setting and it said that it was already enabled. I disabled it, then turned it back on hoping it would maybe change something/reset it.

It didn't work but it caused a handful of other issues.

Now, when I turn the truck on, I have a service abs system message, a service trailer brake system message and a park sense off message as well as a handful of codes. U0001, u0212 and u1412. Also, my center screen now shows 0 on my mpg gauge screen even when driving, my distance to empty is counting down rapidly, my average mpg screen is counting down rapidly like it's not getting any signals etc.

I tried clearing the codes and they came back.

What did I mess up and how do I fix it? I don't want to start messing with other stuff and cause more issues. My guess is that by turning that module off, it automatically turned off some others in the process and those need to be turned back on. I just don't want to enable the wrong ones and have other things not work.

Thanks for any advice.

EDIT: SEE POST 2

Ok, I really should read on the forums before I dive into stuff like this. I am pretty sure all of my issues are because I also changed tire size (sorry I didn't mention this as I thought it was likely unrelated) and did not do the ABS procedure as listed in the tire size change thread. The truck is getting some other work done right now but I will do the ABS procedure as soon as I pick it up and update if that solves everything. I got to thinking that all of that seems to be ABS related since if the ABS system has faults, that would cause the trailer brake system to not work and if the trailer brake system isn't working, that would cause the back up sensors to turn of like they do when a trailer is connected.

This looks a bit familiar. Was the engine running when you made these tweaks?

I suppose you haven't read the AlfaOBD thread before you jumped in and started tweaking the settings.

One of the most important details that is outlined at the start and repeated several times throughout the thread is to make a copy of the default BCM settings before tweaking anything.

I recently had a very similar experience after using AlfaOBD for quite some time.

I screwed up by simply tweaking the wheel circumference settings with the engine running.
I had all those items you listed, as well as a dead EVIC and no power steering (EPS).

And, I was pulled over at the side of the road in the middle of nowhere. LOL

The long story short and lesson I learned, the ignition stays completely off unless AlfaOBD instructs me otherwise.

I had been driving home from an oil change and warranty check at my preferred dealer, and decided I would update the wheel circumference settings after having the summer wheels installed.

It was hot, and the AC felt great, I had the tunes rocking, and it all hit the fan.
Lucky for me, I knew one of the SAs at the dealership was familiar with correcting BCM faults.

He agreed to wait for my arrival and had me back on the road in less than 10 minutes after resetting the BCM to the default settings. He was clever enough to print off the BCM state when I arrived and kind enough to supply that info to me.

I can scan the document and post it here shortly, and you can check your settings to see if that's the root of your grief. There's no guarantee, though, because your truck isn't the same as mine.

After reviewing BCM change details from the dealer, it appears the only changes he made were undoing the tweaks I had set. I have no idea what changed to kill the EVIC and EPS, but after the dealer reset the BCM, everything that had failed on the truck was restored.

ABS
EPS
EVIC were erratic or non-existent after I tweaked settings with the engine running.
I have no other explanation.

Your best possible solution is to have a dealership reset the default settings.
Hopefully, you can locate a dealership that will perform this reset for free or only a modest charge.


Or, find a donor who has the same truck to supply a copy of their BCM settings, but that could open another can of worms.

Did you make a backup before any changes by chance? Sometimes it's best to go back to known good before proceeding after something like this. It's not unrecoverable, just a lot more work if you didn't.

I did not unfortunately. I didn't even realize there was an Alfa obd section on this forum that would have told me to do that before anything else. Lesson learned.

I am hoping that doing the final steps of the process for the tire size change process will fix my issues as it seems like that is what is happening. Just got a get the truck back this afternoon and try it.

If not, I'll guess I'll have to go to the dealer and have them flash the bcm back to stock settings.

Truck was not running when I did the adjustments. Hopefully, it will be as simple as doing the abs procedure and then clearing the codes as instructed in the thread. If not, I'll just have to go to the dealer and have the bcm reflashed back to stock settings.

Thanks for the info.

You won't have to do that. In fact, it might not help and the dealership will charge you for everything you need set right. We can get you squared away. Just ask questions here...you are right that ABS initialization should get you back to normal.

For anyone that may help, please list ALL of the changes you've made or think you have made. That will help us right the ship.

Reviewing all your posts again, the features you describe look like a classic B+ fault or a module stuck on and spilling garbage into the CAN bus network.

The first and easiest test is to load test the battery with a toaster-style battery load tester like this $18 device from HarbourFreight.


Another late-breaking thought: have you tried pulling off the negative battery terminal for an hour? I'm thinking the only thing that my dealer accomplished was possibly re-syncing the BCM to the CAN bus network, which can likely be accomplished with a power cycle.

Try the power cycle before the load test.

Sounds good. I will try the abs initialization as soon as I get the truck back and let you know if I am still facing issues. Thank you!

No problem. Also now is a good time to take that backup before doing anything else. It may not be clean since you've already made changes, but it's a start. THen you'll take another one when everything is good to go. To do so:

1. Create an AlfaOBD Backup of your current BCM Config (Body Computer -> Body Computer My2015 Powernet -> Car WIth Hood Open Icon - > Select Procedure to start -> Backup Vehicle Configuration to File)
2. When Complete go to the Hammer and Wrench Icon in the top right of the app and select Upload to Google Drive (At this point use the sign-in button at the top of the screen if not already signed into your g-drive).
3. Select Upload Any AlfaOBD File -> BCM Config -> ConfigBackup(Todays date and time)
4. Read the System ID and Status of your current BCM Config (Body Computer -> Body Computer My2015 Powernet -> Battery Icon - > Read System ID AND THEN Read System Status. This will create a readable/printable log of all your current setting selections not in Hex format but in English
6. When Complete go to the Hammer and Wrench Icon in the top right of the app and select Upload to Google Drive (At this point use the sign-in button at the top of the screen if not already signed into your g-drive).
7. Select Upload Any AlfaOBD File -> Faults and Status Log -> Body_Chrysler_Info

The first file is unreadable by you but is what you would use to restore a known good BCM config in it's entirety. The second is in English and will be a complete listing of the current BCM settings and their status.

Ok created a backup file first, did the ABS initialization process and all is well again. Whew! I created a backup and fault/status log after as well so I should have a good file to go back to in the future if I have any other issues.

My speedo is still off by about 1-1.5mph so I will have to play with the tire size a little to get it adjusted correctly and, the "heated seat module" option didn't seem to fix the soft key issue I have so I will likely have to replace the actual module with a newer version to get those working correctly.

Thanks everyone for the thoughts and help. Lesson learned to do a little more reading next time before diving in.

@Mpgrimm2 might be able to tell you what's needed for your seat issue. Send him a PM with your trucks info and the radio swapped in.

Edit: I'll also pile on to my original and say with AlfaOBD it's safe to do things that others have confirmed already and rather stressful to try something new. Not all changes in AlfaOBD show up right away and require the vehicle to sit overnight, go through several power cycles and/or reach a certain speed before a setting takes.

Glad you're up and running, you'll find that AlfaOBD will save you A LOT in dealership service fees!

Thank you! I sent him a pm.

I have a very nice autel scanner that allows me to do a lot of things already. I can actually do the tire size, tpms pressures, initializations for many things etc all from it but it doesn't have the ability to turn on and off modules/options etc so I figured Alfa obd would be a nice addition.

I'll make sure to read up on things to see if they have been done in the future.

Replied to your message...
On screen seat controls are a 13-15 BCM limitation issue and won't work at all without a CanBus interface/translator module between the radio and the truck. (ie Customtronix Enzo)

(PS: swamped with day job stuff, will be slow to reply to messages for a bit)

Does swapping BCMs to 2016+ fix this?

It may. IDK for sure... @Jimmy07 or @Roman217 may be able to confirm.

 

[SitKneelBend]

Actually, @reyokonova might be able to answer this now that I think about it. We just swapped his BCM in his 2014 to a 2016 and he's adding heated cooled seats and the UAX 4C radio...
