I had this issue recently on my '18 3.6 Crossroad. The heat wasn't consistently hot and my coolant temp was rarely of 185. And that was after letting it warm up for 10-15 minutes. I'm down the Jersey Shore, so not artic like temps, but cold enough. I had the thermostat replaced and a coolant system flush. That fixed it right up. Now it get too hot sometimes.

Nope. It's a push button with passive entry. From what I've seen online, if you can get the PIN from the RFH, you can program new fobs with the remote start. The funny thing is, I can go into the Body Computer and activate the remote start, enable to hood ajar sensor, I just can't program a key fob to see if it works. I can even reset the ECU. Under RFH, I can locate learned keys. I just can't get a PIN to work. And I have 2 of them. I reach out to AlfaOBD directly. They had me send them a screenshot of the RFH Read System Status. They said "Please send me the output of the Read System ID feature for the RFH, I need the ECU Variant ID and ECU Version ID to check the Read PIN function." Hopefully, they can figure something out.

Thanks for trying that. I really have no clue why this is happening. I bought the car used from a used car dealership, so not much on the history. The SGW was not secured properly. It only had one screw holding mounting bracket in place, so I wonder if it was replaced at some point and not synced to the car correctly. Or maybe the RFH was replaced and that's why I get the 2 different PINs. Or some other module that I'm not even thinking of. I do have a loose purple plug in there that I have no clue what it goes to. I don't remember how may pins it is. Hopefully, I can get it sorted soon. My goal was to program the new fobs and activate the remote start function. This is just my luck though. I buy the car that can't be modified. Thanks again for your help.

Thank you for responding. I attach the OBDLinkMX+, open AlfaOBD. Under Select Car Model I choose Dodge Journey (JC). Under Select Function I choose Radio Frequency Hub (RFH). From Select Control Unit I choose Radio Frequency HUB MY2011+ PowerNet. Then I connect. That all works fine. I then hit the "Hood Up" button, select Read PIN under Select Procedure to Start and I get the Failed messages in the images below. First I tried the generic 12+8 bypass and that didn't work. Then I ordered the bypass module from ZAutomotive, as linked on AlfaOBD's home page. I tried that today and got the same messages. If I leave the Read PIN page up, hit the "Key" button at the bottom of AlfaOBD to go back to the connect page, disconnect then immediately reconnect and while it's reconnecting hit the "Hood Up" button, I get 2 PINs. First it shows a PIN that is 4 numbers, then it quickly changes to a PIN that has 2 numbers, a letter, then another number. If I try those PINs to program a key fob I get similar Failed messages. Any ideas?

I hope you're still around and that you can offer help or suggestions. I have a 2018 Crossroad AWD with the 3.6L engine. I bought the OBDLinkMX+ and alfaOBD for android and have that installed on my phone, Samsung Galaxy S23 Ultra. I keep getting an error when I try to get my PIN from the RFH. I bought 2 different bypasses. One off of amazon, though it is a no name brand, Exctool. It's has 2 pig tails on it for the 12-pin and 8- pin plugs with a port on the other end for the OBDLink. When that didn't work, I bought the ZAutomotive Gateway Bypass Module that alfaOBD has on their web site. I still keep getting errors when I try to read the PIN. If I disconnect then reconnect and quickly go back to the read pin page, I get 2 pins, neither of which work. One come up, then quickly changes to the other. I'm at my wits end and feel like I'm just throwing money at it in hopes that it works. By the time I'm done, might as well have just paid the dealer, or so it feels. Does Jscan work better than alfaOBD? Anything you can come up with would be greatly appreciated. Thanks in advance

Mine is a little finicky. With the AC on (both front and back) shut the back off first, then the front. Make sure the back is at off. On mine, there is a "dot" for off and then it can go one more click to "AUTO". If it is on "AUTO", it will still come back on.

Do you have controls for the rear vents in the head liner? If so, you have to make sure that is off as well. If that is on it will keep turning the front controls on.

My kids are on it so much I forget it has more than cartoons and annoying kids songs that get stuck in your head for hours on end. Thanks again for the video.

Thank you 2late4u. That's exactly what I was looking for. I didn't even think to YouTube it. Thanks again.

jkeaton - Yes that would be easier, thank you for the idea. I have an extra USB port from when I did the conversion in my Nitro. At that time I bought 2 2 packs and installed 3 of them. One in the dash and 2 in the center console facing the back seat, just incase I need to charge the kids tablets. I know those ports work great from experience. John/Horace - Thanks for the link. Very useful information. By the way, love your avatar picture. I just really need to know if I would need to take the whole dash apart in order to replace the port or if the port can just pop out. I read on another thread, while looking for info my my little project, that the start button can just be popped out to be replaced. I might just have to go out and play with it to find out. Thanks again to you both.

I was wondering if anyone has tried to change the 12V charging port under the radio to a USB port? I have 2018 Crossroad with the 8.4" display. I was wondering how hard it would be to get the 12V out and put in a 3.0 USB? Would I have to take the whole dash apart? It seems to be molded into the dash. I did this on my old 2011 Dodge Nitro. That was simple though. All I had to do is pop the radio bezel off and it was right there. Any help would be greatly appreciated. Thanks in advance.

Thank you and thanks for the welcoming. Everyday I drive it I like it more and more.

Hi all, I'm Chris from NJ. This past Friday I bought a 2018 Dodge Journey Crossroad AWD with 53,875 miles on it. I had been looking for one for a while. I needed to upgrade from my 2011 Dodge Nitro SE. I look forward to learning about my new ride. So far I love it.
