Alfa OBD and 4 digit pin.

[Jammer24]

So I jumped on the wagon with alfaOBD and the mx+ on android. I attempted to program a new fob and it asked for the four digit pin. So I called the dealer and they told me they couldn't give it to me. Had to take my truck to them and pay them to do it. I was able to change tire size and TPMS thresholds with my autel ms906 with no issue. So i was able to go into the alfaobd and find a four digit pin. However when I tried that pin it didn't work. It said the key needed to be in the lock position. I would guess that the key just needed to be inserted in the position allowing you to pull the key out.....The one message said that I only had three attempts and something would be locked. second attempt was the same only i put the key in the run position. at this point I backed out and are looking to the pro's

Also I read the page or pages for setup of alfaobd and found I didn't have to do any of the settings it was showing in the setup instructions.

Same here.... 2019 5500
Everything I read was all about "it's so easy" "do it yourself" bla bla bla...

I haven't done it yet, because I live about an hour away from the dealer, but from what I understand with my situation is the dealer has a security code that even they have to enter to access specific settings. The dealer has to physically connect to the truck to gain access to the code. It's not something that can be provided over the phone.

All of this could be absolute garbage info that's being provided from the dealership, but I have yet to locate another workaround.

I have not seen in any video someone entering anything more than one four digit code......I was able to get in with alfa and pull my trucks four digits. questions is......................is it the correct one? the other choice or default as I took it was 0000 if it didn't have one. Now I watched a video where a guy went in and pulled the pin with alfa......so I'm sure i'm in the right place......not sure this is why I'm reaching out.......thing is once we learn all this it will be easy for us.......ROTF

AlfaOBD pulled the correct 4 digit code when I programmed a new fob for my '15.

I used a different app, Chrysler Pin Puller, cost a few bucks for the "tokens", but it worked first time. Same use, I was programming a tip key.

Because it is.

Alpha ODB gives you the 4 digit PIN you need. Unless they did sumthin different on the 5500s

 

[Jammer24]

The four digit pin I pulled didn't work for my programming. I tried did two different trucks...... How soon does the (three failed attempt lockout rest??)

Mine pulls no pin at all. It fails.

This happened to me too on my buddies 2019 classic. Alfa couldn't pull it, I ended up going the pin puller app route. I think it has to do with updates they make to the app. Some options just stop working after updates in my experience. I have had to email the developer a few times with issues in the past such as the VGT calibration procedure being broken, speed limiter not working etc... Send the dev an email through the contact link in the app. He has always gotten back to me within a few days.

AlfaOBD pulled the correct 4 digit code when I programmed a new fob for my '15.

Not sure what I did wrong if anything. I had no issue pulling the the pin. I scrolled down to read pin and there it was.....I guess i'm a little worried to try again until I find out when and if the (3 failed attempt lockout resets).
So just went to find the link for the fob's I purchased to realize I purchased the wrong ones. They only cover up to 2012. Not sure how I missed that...

Just FYI, 2019+ years started using rolling 5 digit pins for programming key fobs. You guys with the newer trucks can no longer do it on your own.

For what its worth...My dealership gave me the four digit pin without charge. They wouldn't do it over the phone, logically. I had to go into the dealership and show proof of ownership. Registration and DL.

Are there instructions on how to use the Chrysler Pin Puller app? I downloaded it, bought the tokens, etc. but it tells me I need to connect to an ELM327 device? That is some diagnostic machine that I'm not buying. I assumed I could connect the OBDII reader to the AlfaOBD app and this would work - is this not the case?

Admittedly, I'm pretty much dumb when it comes to this type of stuff. Programming, electrical...not my forte. I need stupid dummy "explain like I am 5 years old" instructions.

 

[RamDiver]

The ELM327 designation is a specification for the OBDii interface protocol.

In other words, an interface that you connect to the OBDii port must use a communication style that both the App (AlfaOBD or J-scan) and the OBDii port can understand.

If you have the correct interface that allows you to use AlfaOBD, you should be good to go.

An OBDii reader or scanner is a device used to read diagnostic trouble codes (DTCs) and has no ability to act as an interface for software apps other than those embedded in the device.

An OBDii interface such as OBDLink Sx or OBDLink Mx+ (sometimes referred to as an OBD dongle) is an interface to connect from a vehicle's OBDii port to a PC, phone or tablet using a USB or Bluetooth connection.

Many members use the OBDLink Mx+, a Bluetooth interface, with AlfaOBD and an Android phone or tablet.

I would never encourage this method because I believe that the Android OS is unreliable for making critical changes as is any Bluetooth connection.

I use an OBDLink Sx that has a USB and connect it to a Windows laptop. It's fast, secure, and reliable.

With a 2018 Ram or later, you will also require a Security Gateway bypass cable. There are many to choose from, several that connect directly to the SG module, and then a few others that only take a few minutes to install, like the KaodTech Security Bypass Cable.

I believe that the KaodTech cable is by far the best choice. I leave mine installed and tucked away during dealership visits, they have no problems using the OBDii connection.

Nicely explained, Ramdiver, thank you

I bought an OBD Link Mx+ before I read this. I can connect to the truck through Alpha OBDII, get to the screen where I can reset the TMPS pressures....but it won't chang them.

I get a prompt that says it cannot tell if the procedure is completed. When I go through and try to reset the Radio Frequency Hub to complete the task (since I don't know if it's been done or not based on what Alpha OBDII tells me), I get a prompt that says something along the lines of "unable to connect to computer" or thereabouts. Except I am connected.

I have no problem buying the USB to computer cable, and I guess buying another copy of Alpha OBD to put on the computer - but what is teh Security Gateway Bypass cable? Not a single mention of that on any of the youtube videos I've seen and the link you provided is out of stock. What purpose does it serve? I just want to change the stupid settings on the TMPS sensors to something reasonable so I can quit getting the damned prompt when I turn my truck on and the yellow light goes away. It annoys me.

 

[schmellba99]

Dammit, I see now after doing some research. Alpha OBDII can't make changes without the bypass cable. That sucks. How long typically does it take Kaodtech to get them back in stock?

Any Ram truck year from 2018 or later requires a security bypass cable to connect to it, regardless of the app you choose.

Many of the older YouTube videos are directions for pre-2018 model years so, there will be no mention of a security bypass cable.

With the older trucks, it would be possible to connect an interface directly to the OBDii port to make use of any compatible app. Then FCA decided to protect us and our trucks by using encryption and installed a security gateway module. (sarcasm)

Have you written to KaodTech to inquire about the expected availability for a suitable cable assembly for your truck?

PS; the app name is AlfaOBD. The current vehicle interface is know as an OBD2, aka OBDII, aka OBDii.
