RF HUB Maybe?

[JKW3512]

My 2021 Dodge Ram Laramie will not start. It wont even come in ACC Mode. From all the research I’ve been doing; I’m assuming it’s the RF HUB that’s lost connection some how? Where do you get this part from? Should I just get it towed to the dealer. I purchased an Autel MaxiCOM 808s and gave me these faults - ABS (Anti Loc Brakes) 2 Red. BCM (Body Controller) 1 Red. Radio - 1Red. SCCM Steering Column Control Module - 1 Red. ESM Electronic Shifter 2 red - AMP Amplifer - 1 red - DSM Display Screen Module - 1 red. Any help is greatly appreciated.

If your Autel scan tool shows on the network topology screen that these modules are red that means that they are not communicating on the bus.

If the truck is under warranty I would take it to the dealer. If not, can you see the RF Hub on the network topology? Is it green like it's powered up and communicating? Can you see any DTC's in the RF Hub?

I'm having this exact problem with my 2013. Insert key fob and all it does is light the gauges and show me mileage. Doors still unlock with the fob. And my scanner won't connect. Any ideas?

@Bob_the_Builder, dealing with a similar issue. Swapped out WIN and RFHub with new fobs. I swapped out all of the major fuses and relays from my working 2500 and still nothing.

Dang, I'm supposed to have a rf hub on the way but the company isn't great at getting back to emails so I'm not sure if it'll be here today or not. But now my key doesn't do anything at all. Won't lock or unlock the doors. Dash still lights up when I open the doors and I'm able to connect the scanner but only if I jump relays manually. I did get a cable and alfaobd but it can't find the rf hub.

How did you determine the WIN was working and then decide the RF Hub wasn't?
