Chrysler SKIM Thread 2.0

[Dontov]

Hi,

I posted in Engine/Gas section (title : "Challenger 3.5 stopped and never restart, no DTC on VCM, SKIM or key issue ?", but perhaps better here, as it can be SKIM related


Firstaval, i'm in Europe, so, not able to went to dealer, as there is no mopar dealer here.

A friend of mine have a dodge Challenger 2009 3.5,
engine stopped in september, when driving,
he find a garage sp?cialised in US Car, but choose the wrong one (knowed to be one of the worth of the area, lie, expensive, bad work...),
the garage... done what is done (perhaps nothing, despite asking large bill and, as i see when i see the car this saturday, unplug a air tube, and also the air temp sensor....).

So, all i'm sure is just this, cause i tested and see result :

1. all air stuff seems to be right now (i replug all)

2. the car don't start (good voltage, battery, and test with a voltage donner car, 12.35V as i log on VCM)

3. the fuel came (unpung a spark too see if it's wet or not)

4. no spark (not au all)

5. VCM can communicate (no issue)

6. no DTC code (from VCM, tested when engine was stopped, and tested when engine was in startering action)

7. PCM was swapped with a good one (had tested original and the swapped, good VIN when VCM reading, and download all the tune of the swapped one)

8. not sure about the process to swap one, so perhaps the SKIM/WIN is entering in theif mode

9. friend have just one key, only one

10. VCM SKIM data are (whatever the PCM tested) :

SKIM STATUS: unknown: 01 11
SKIM/VTA Status : SKIM Learned
SKIM/VTA Status RAM : SKIM Learn... (..."ed in RAM" i remerber)

11. SKIM part in the tune seem to be ok in VCM, exact same as the Dodge Challenger 2007 3.5 find in HPT repository

SKIM : Disable
SKIM Capable : Enable

12. FYI, i use a end 2020 version of PCM, not the lastest of 2021, but not an old one

I readed SKIM is not yet usable with VCM, perhaps just testing since one or two years
I readed a ton of "dodge not start" related to SKIM/WIN
But cannot find the best route to fix that

I cannot fix that situation with VCM i presume ? (does exist a beta to test ?)
It this normal i can't see any DTC in VCM ? (i read about WIN process, and "B1A29-Skim Basestation Mismatch", but i don't see the B1A29 in DTC)
Can it be a SKIM issue ?
Or a WIN issue ?
Or a KEY issue ?
How can i diag this to be 100% sure ? (i read about WiTech stuff, but what is this ? price ? licence or other ?)
And what i have to ask him to buy and how can i do to fix this ???

Best regard

There is a "reset skim" procedure but it does not wipe the VIN, i.e. no noticeable effects. The DRB can program VIN into a SKIM or PCM module but only new ones, once a VIN is programmed you can view it but not change it. I've never been able to enter the VIN via DRB anyway because normally you use the "PCM Replaced" or "SKIM Replaced" functions and it copies the VIN from either the PCM or SKIM, whichever was not replaced. I used my HP Tuners software today on a 99 XJ to disable SKIM in the PCM and it worked. But I unplugged the SKIM module before I flashed the PCM with the tune.

There is confusion on how to write the VIN with the DRB3 on a used PCM (I do them all the time).

1. Ensure communication with the PCM.
2. Select "Engine"
3. Select "Miscellaneous"
4. Go to "Check VIN" (Enter)
5. Then select "Page FWD"
6. Now you can edit the VIN.

Hope this helps someone.

There isn't much to share at the moment. We need beta testers that can give feedback with what works and what doesn't so I sent him a PM.

any updates on this ??? i just used 2 credits for something that doesnt work apparently

It will never work and HPT doesn't care.

They also will not refund you.

Since I'm retarded and dont know how to sub to a post, I'm subbing by commenting. Would love to see JTEC and JTEC+ skim workarounds.

I can delete SKIM on the older PCMs now. Unfortunately, it wasn't HP tuners that made it possible. And it cost me about 2 grand to make it possible :-(

I should be able to delete SKIM on all those older 3-connector Dodge PCMs, probably from the 96-04ish era.

What did you use to disable the SKIM? I have a TJ in the shop at the moment with SKIM problem. I have a DRB 3 and also CDA. We are based in South Africa

[spoolboy]

See if this video helps you:

[motoxxxman]

so is it safe to say that HPT still doesn't support SKIM delete for 2001 JTEC+ Jeep ecm's?

[Jim P]

Until HPT announces otherwise? yep

[Bertus76]

If anyone needs the skim removed, I can do it on just about any one, pm me or send me an email, [email protected]

[Joodan]

Anyone see the diyhemi christmas video? Looks like hp tuners supports this now

[Blake @ TSS]

Yes, I watched the video. Looks like there are still a lot of loopholes in claiming it "works".

This is Blake from DIYHEMI. This is my old HP tuners account.
Yes it works for us and we tune many ecms a week.

Hi, I have a 2006 Dodge Dakota with black non security key, and manual transmition, and Can network.
The orginal PCM Part no was 0594895ab with software 05094054AI. The replacement part was taken from Jeep Grand Cherooke. That Jeep was equipt with Skim and automatic transmision. The ecu was flashed to proper software 05094054AI and the vin was modified. Unfurtunatly the car dies after 2 sec. Anyone can help how to approach that problem. I do have Hptunners,
It looks like it is NGC3 Can Pcm.
I am not from USA , and there no expertts in that subject in country.

[Backwoodsracingllc@gmail.]

it don't always work spent the credits for it to start and stall. but on a plus note I was able to disable skim on 2 07 ecms.

[LamontCranston]

You are all welcome to flash your pcms all you like. If that's what works for you, by all means do it.

If you want to retain your remotes working though, you need to use your skim. Of you want that light to go away, you need to use your skim.

I can fix broken skims or clone the data into another skim. I'm not here to replace anyone is step on anyone's toes. I can be reached via email at [email protected]

I had the same problem with skim as a dodge durango 2000 4.7, I managed to solve it as follows. Step 1: remove skim and vats with hp tuners. (When doing this, it only turns on for 3 seconds). Step 2: connect the alarm module to ground and power and to the pair of communication cables with pcm and finally just turn off the alarm and my swap turned on without problems

So, ultimately, it sounds like it is best done by disabling SKIM and VATS in the donor vehicle first before swapping?
