2017 Dodge Challenger RFHUB VIN REPLACE

[AvechuchoAxel]

I need help to change vin # on this RFHUB from a 2017 Dodge Challenger.

I did changed the existing VIN# (swapped) x4 times, but after conecting to the vehicle it shows only 00000 as a actual vin number.

Attached are the AFTER/BEFORE files. Thank You.

1) Original
2) My modification
3) After installation

Here is file with corrected CKS, i am not fully sure it will work. Please provide feedback after you try it.

[AvechuchoAxel]

It still shows VIN# 00000000000000000 Now not even cranking.

Thanks

You changed it in the dump?

Or did you use a obd tool?
Should be easy,
Done a few win, abs and ecus.
All by obd.

Look at the last byte of the CKS ... it was different from the previous 2. It had E0. I edited to E9, but it didn't make any difference.

Hope picture sizes are ok....

Thanks

Do you know how PIN is stored ?

I did try with OBD2 method... AUTEL won't let me write vin#'s ALPHAOBD can't do it neither. I have a micropod 2 but no software or app installed. How did you manage to change VIN#'s ??
ECM changed OK, BCM I did it by DUMP because also AUTEL won't let me write back the new number, RFHUB Autel refuses to change VIN#, thats why I choose making the mod by DUMP but apparently CKS is my issue.

Thanks!

Io terminal does full read and write. IM still waiting on a virgin rf hub from dealer to read out and save ....

[rob h]

Io does do some.
Not all.

Option erase vin, in alfaob, would be you best option.
But you have Tried that,?

If you have the pin,
Maybe you could ad a key.
Then go for the obd options again.

Even if the rfhub not matched to a car, it could work.
Most pin reading tools, read pin from rfhub, or bcm?


Never Tried this myself,
Just a guess

Hey what’s going on .. were u able to resolve this issue . I’m having same problem

[rob h]

What exactly,is the problem?

Last car, 2020 Ram, i swapped the processor in the rfhub.
After water damaged, data was still ok.



Changing vin, in rhub dumps. I have not seen anyone confirming succes.

Dealer tools, can unlock used modules.

Placing a strange rfhub, could messup the vin in the bcm.

Best to backup the bcm with a programmer, before you put the new rfhub in.

Just replaced an RFH on a 2013 RAM diesel with a Autel im508s. A virgin RFH doesn’t have a VIN and the PIN is 0000. In this condition mine started, but shut off after 5 seconds, You have to find a function called RFHub replacement. That function is under the diagnostics side. Do that.

[rob h]

He is not talking about a virgin rfhub. But changing vin in used components.

If you could share the partnumber, and your virgin files.
But you dont seem to read the posts. So i guess, you did not read the virgin dumps either.?

[CasMo]

Unfortunately I don’t have the virgin files for the hub as I got called to program it and the outfit already had the new hub installed and had a no crank no start. This being said, if you replace the RFHub, you need to virginize the keys or buy new keys and program them to the replacement RFHub too. That’s why it didn’t even crank after that other guy putting the VIN in the file and due to mismatched keys. At least it is that way with my Autel. If there are better ways to do things, I am always up for suggestions. So who didn’t read the posts again?

[rob h]

The old keys, dont need to be replaced. Locked to this vehicle they should be accepted when you reprogram them to a new rfhub.

If your vin is off in your hub, then it is best to program new. I dont think, it will accepted used with another pin.

Xhorse does let you created these keyless keys, that you can reuse over and over.
The mqb style xhorse key, does have the battery on the pcb, allowing you to use the print, without casing to interfear sginal.
I use these on Ram 4 and ram 5 to test. They work fully.

[qeso705]

Hitag2 smart keys from FCA are possible to reuse without virgin as far me is known. I doubt in Dodge will be different.

[CasMo]

The original Hitag2 keys that came with the vehicle cannot be reprogrammed once they are locked to the vehicle (RFHub). If I read them with the xp400 they even show status locked. For shits and giggles I tried to program a locked key and it wouldn’t program. Had to put a virgin file to the key and then it programmed up like nobodies business.
Once you change out the RFHub you need to program up new keys (at least one) first. Then you do the RFHub replace, which marries the RFH to the BCM and the VIN from the BCM is getting copied to the RFH. Done.
A new virgin RFH has a VIN 0000000000000 and a PIN of 0000. The newer Dodges come with the RFH VIN locked. It is not possible to learn a different VIN to them, unless maybe someone gets a hand on a virgin one and reads out the RFH and flashes them files directly to the used RFH. Kinda same idea I did with the original keys.
Unfortunatly I don’t have a Xhorse programmer yet, only got the IM508s with a XP400 from Autel. Maybe in a year or so I can afford another programmer and I’ll try to read more modules and post them files.
The RFH in the Autel diagnostics function is hidden where the radio is.

Hey buddy did u ever get the new rfhub for virgin readout ?

Hey what’s going on so ur saying vehicles 22-23 Rfhub are locked and can’t rewrite vin ? If so there is no way around that ?

[CasMo]

Yes, Dodge locked the VIN in the RFHub in the latest model years and you just can't put a different VIN number to it (at least it is like that here in the North American market). Same like factory Hitag2 keyfobs. I suppose if one has a virgin RFH and make a virgin dump one could maybe flash the used RFH and get it going virgin again that way.
Others changed the original VIN on the BCM, PCM etc to mach the one on the RFH. I just find that later idea gross and isn't a real fix.

2019 Dodge Charger Virgin RFhub pin code 0000

[CasMo]

The chip on my RFH is different... XC2265N... and off course the XP400 can't read it.

[rob h]

You could invest in a vvdiprog.

If you order the exact partnumber rfhub, you could make a backup.
And perhaps share your files, like other do.

yep… unfortunately at the moment I can only do what the IM508s and the XP400 can do. I am not a stranger in electronics repair, just have a bit trouble on what programmer to use for whatever brand / module.

[dashtool2016]

I have the same problem with vin 0000 unprogrammed key I try to read pin code with alfaobd and it gives me pin 00C6 but when trying to program it says incorrect pin code I tried to change vin in eeprom 95640 but also without success they have schemes to read flash and eeprom microprocessor? I don't see the connections in vvdi

[rob h]

If you show us a picture, of the pcb.
And what kind of mcu is in there?

9S12XEQ384 ?

What tool are you using to read the pincode? Besides Alfaobd,

670102548 RFhub 2016 Maserati Levante M161

What happened to the original rfhub?

The 4 digit PIN on the RFHub is numeric only, no letters in there... At least I haven't seen any letters in the PIN yet. So 00C6 reading is garbage IMHO. Also this PIN is for the fobik only. BTW, the PIN can change from 0000 to whatever it used to be without loosing the programmed fobik.
Try programming the fobik with PIN as 0000.

[dashtool2016]

it does not accept 0000 can someone tell me the pin of the dump

[Freshfresh]

IM able to change vin in rfhub if service needed hit me .. send me file with updated vin and i can get it done for you

[SummitMate101]

I found out Lickety Split can solved this issue! I used them on a swap for a SRT 2022 Charger and it was affordable that is there whatapp @ xxxxxxxxxxxxxx

[sauto]

hi, am also having problm with rfhub can you share the number who can help me thanks

[willa615]

Did you ever solve this issue????
