Please watch the whole video to understand the beginning!

Thanks man! I just picked up this jeep a couple weeks ago and now it's running cherry. JUST AN FYI FOR ANYONE WITH OVERHEATING ISSUES AND GETTING THE p1499 code this also fixed that. I guess my old ECU wasn't giving the solenoid power and thus the cooling fan only ran at low RPM where it should be running very high RPM to keep engine cool especially at idle! I thought it was the solenoid but after doing this I haven't had any problems!! Keep in mind this is only for the Hydraulic cooling fan on 4.7 GC's. Awesome video bro!

Remove the SKIM halo. Remove the PCM on your firewall. Take it to your Auto Zone & they will delete the SKIM info. All you need is the VIN, mileage numbers. Put the PCM back. Don't replace the SKIM module halo & you're good to go. It's only $198 with the core or $398 without. Update: Make sure to disconnect the battery before removing anything. It's called "flashing" the PCM. My car is a 2004 Jeep Grand Cherokee.

THE "ACTUAL" SOLUTION:" On my 2000, the problem exists within the SKIM immobilizer. Remove the steering column cover by removing the single screw that holds the bottom portion on, then separate the two halves. Thereafter, unscrew the immobilizer upon removing the wiring connection, and carefully remove the round portion that goes around the ignition key tumbler. Carefully separate the two halves of the immobilizer and you'll see two relatively large solder points. They attach the wire that runs within and around the key tumbler. If you look closely, possibly using a magnifying glass, you'll see hairline cracks in the solder. If so, re-flow the old solder with some new solder and reinstall. Then, look at the lower half of your steering column cover. See that long boss that the screw you removed runs in? Take a Dremel and remove half of it long ways, leaving the half that isn't slamming into your immobilizer every time you tilt your steering down (Courtesy of Chrysler). Oh, and if you tilt the steering down, further hold it there, and the car starts when you turn your key, then this is likely your problem. I ran my car that way for years before figuring this out... cheers!

HEY FOUND THE FIX! I had this same issue. There is a rubber boot in the passenger side door and the power wire, which is a thick brown wire with a white stripe, is probably broken. These models made the ground wire good, but the power wire in the doors is too long, gets caught and snipped. I found a youtube video showing issue, checked mine and fixed in five minute.

Thats badass. My jeep was giving me such a headache. That's what my mechanic said it was too. Awesome info and video, thanks!

A couple of things. You need to also have the replacement PCM coded to your car. The people who deleted the SKIM on the replacement PCM would normally have asked you for your VIN so they can do that. Also, you MUST discard the skim reader so that it is never reconnected because if the reader is present it will reactivate the skim in the PCM and you'll be back to square one.

I got upset...when u pulled it apart and put back together.. Cuz I didn't understand ...but once you explained it.....later...I got it

Pretty much the best f****** vid i've watched on topic. Thanks man you are a hero. 👍

I wish I woulda known that you had to unplug the SKIM sensor BEFORE powering up the new “plug and play” PCM I had bought and installed into my WJ… It bricked the PCM as a SKIM equipped vehicle and made it have the exact same issue as before… They should put instructions and not just tell people “plug and play” when selling things like that… Sold the vehicle before I found out the proper way to do this cuz as he states in this video there’s a lot of bs and not a lot of this definitely works info out there… so thank you for making this video and showing people the correct procedure cuz I sure as hell woulda liked to have this knowledge prior to selling a beautiful vehicle for such a simple fix once you know how… the dealership couldn’t even tell me the correct way to remedy the issue and two shops couldn’t either…

I actually tried this and bought a computer with the skim deleted and did what he said and it worked

It's wild to watch how long this takes, when I can just do this is 5 minutes via OBD... lol

Man... Thanks for the efforts and all the explanations you mentioned in this video. Just a slight correction, you still can use your old PCM without ordering a new PCM, just get the SKIM disabled as you've mentioned and you will be good to go. HP tuner device can get the job done without removing anything from the car at all... Thanks again.

Great video! Where did you get your ecu reprogrammed?

So the fix is changing your pcm? That’s not a bypass. That’s a delete of skim function.

So basically this video just shows how to swap your PCM

Dude great video man, on top of showing us how to delete this stuoid trouble prone skim, you tell the sizes of each nut and bolt. Kudos buddy

probably the best tip on skims bro 🏁🏆🏁

Not sure if i understand .... why not just ground out all of the electrical charges overnight like you said and THEN REMOVE the SKIM module before you "reboot/ re-connect the battery? Not clear on why .... what does "flashing " do differently than "draining the electrical and rebooting ?

Do you have to change the PCM? If so where do you get it?

Fascinating . Informative. Interesting. Thank you for teaching me, Sir

Other than the 3 commercials......great video

worked for me all i did was remove the water resivoir and boom 20 minute job thanx

Totally been looking for your channel! Love it! Have an 2004 JGC!

I have a 2000 grand Cherokee with this problem. It was pulled behind a motor home and is in mint condition. The odometer say 175,000 miles but there is no way it has 175,000 driven miles. The driver seat barely has anywhere on it and almost looks just like the rear seats that look brand new. It’s been sitting up since 2018 and I’m just now seeing this video. I would love to get it running and start driving it again. So let me get this straight…. What I need to do is pull my PCM out and order a new one. But when I order it, I’ll have to tell them that I want the skim to be disabled, or laying dormant, right? Also if you’re ordering a new one, what is the purpose of getting it flashed? What does he mean by that? Any help would be appreciated because this excites me

Hey, could you help me finding a suitable PCM for my 2001 Jeep Grand Cherokee? Located in Norway

Thanks so much!!! I really appreciated watching the video you made on the SKIM UNIT. Great going guy!!!

My question, I ordered a new or used pcm, ignition, skim and key that all came together and we put it in, car cranked but didn’t start, but the key light did not come on. I never got it started before the key was lost by ????? ( wasn’t me) can I just take the computer out, get the computer flashed and take out skim, and then install the old ignition that has a key? Or is computer not capable of forgetting the former skim?

Hey. Out of curiosity could you have also just called a locksmith to program a new key and would have that worked? I’m experiencing the same issue.

What other one on the bracket?? Missed a whole part there...dod you get a new one, did uou have to reprogram etcetc...

I took the slim out send it in like you said they sent it back they said they erased it or deleted it wherever start but won't turn over

You're a bloody legend! Thanks heaps👍

I am curious. Maybe you can figure this out, maybe not. When you unplug the skim unit, there is what 3 wires? 4? Is it possible to figure out what kind of 'signal goes through these wires? And then 'fool' it? Could it be as simple as just cutting a wire or three? Or cutting two of the wires and splicing them together? To make the PCM always think that the skim unit it sending the signal for 'key present'....

Just wire tie a chip key next to skim above lock and never worry about it again.

I got a P1686 code on My 2002 Dodge Durango and i had already replaced my ECM but i didn't drive much then suddenly when i did it started acting up as your Jeep did and i don't and haven't used the Original FOB Key since i got the car from my Aunt. Do you think it could be the SCIM for me also ?

great video Ronnie!

Why do you need to program the new pcm to your vin??

Why do you need to remove that if it’s unplugged?

I watch a lot of different people making a lot of different videos you did a really good job no idea which was a little bit more clear is did you use your original PCM and have it flashed and have them put re-put the Vin number in and leave a skim dormant

I’m pretty positive this is the issue I just ran into. I sent a brand new mopar Chrysler PCM for my 05 LJ to Mark at Wranglerfix to be programmed. It looks like they programmed the computer disabling the skim in the computer; however, I have a sentry key immobilizer module attached to the steering column and two keys with the fob that all work together with a PCM that has the skim enabled. So when I installed the programmed PCM earlier today, used the factory chip key, sentry key immobilizer still connected, the Jeep is cranking but there’s no fire. I had no clue about this. Wish I would have been asked this prior so smething like this wouldn’t have happened. I’ve removed the sentry key immobilizer, but was told that there’s no going back once you try with the immobilizer connected- because that connector and it’s wires go directly to the pcm plug and sends it information. The sentry key immobilizer sent information to the pcm that has no skim enabled and activated it is what I been told. It looks like the pcm needs to be reflashed and programmed to my vin and mileage again deleting the skim within, except this time with the key immobilizer out of my Jeep and disconnected it shouldn’t set the PCM off to prevent it from starting. I’m really at a lost for words and have had a migraine for the past 8 hours, reading up a storm about this. This is what looks like happened. The only question I have though is what key am I to use once I get the pcm reprogrammed without the skim and no sentry key immobilizer installed on my Jeep- which key do I use to turn the engine? And will using one of the programmed keys corrupt the pcm again causing another problem like this? I have two chip keys, and I have a non chip key.

I am unclear on what he did in the second part after he removed the battery and the rest of the stuff. I saw him take the SKIM out under the steering wheel (in the first part), but it looks like he just unplugged and plugged the same stuff back in in the second part. Was this to reset something, or did he actually remove something (permanently) in that area?

Please, Did you mean the bypass is to change the computer or its still the same computer??

I have this problem. After we take the ecm out where do we send it ?

Put black tape over light is easy

my computer went bad on a 2004 jeep grand cherokee my dad picked up one at a junk yard and they installed it. The car will start but shuts off after a second. he said the junk yard never programmed the pcm to my vin number How do you do that? If I take out the skim with that computer already installed will it still start AND RUN OR WILL IT STILL DIE ????

Very good demonstration

I didn't need to take the battery out you can get it out by taking off the coolant res and moving the tcu over a bit

Dump girl question doesnt black tape also work on the dash instead of diconnecting the bulb?

Thanks man. Big help bro. Thank you!!!!!!!!!

Hey brother. I have a fob and out a new battery and now having all sorts of issues with electrical components. Apparently that new battery opened a can of worms. I’m having issues now first I noticed all clusters stopped working. Sometimes door sometimes locks, etc… do I replace driver side door control unit? Pretty lost here for first steps getting a lot of different info lol

All computer resources have done a great job with my Jeep's computer also. Quick turn around and no hassle warranty. But I am confused why you would want to bypass the skim module. These old ignition switches will probably start with a spoon if it wasn't for the skim code

Can you still use the chopped key if you do this. ?? I bought a 2000 grand Cherokee but had a 02 motor put in. Prior to my purchase. And has only 1 key ( chipped). Jeep starts for 30secs and dies . Also sounds like relays under hood are clicking with lights flashing when battery is hooked up , Guy I bought it from said needs a new pcm - but with the clicking relays and lights flashing while battery is hooked up. Confuses me . The Jeep does start but pretty much immediately dies won’t stay running. Is it pcm or ??? I’m lil baffled and don’t wanna throw $ out chasing a fix.

This is why 97-98 are my choice of years for the xj .

Would that work on my 07 jeep grand cherokee 3.0 diesel crd

wait. so u unplugged the ecu n plugged it back in :/

Do you have to get a new computer or can you just flash the old one or erase the old one . or is there a way to test the skim unit to see if it is bad. I’m asking because the original key no longer works , alarm came on during hurricane Ian , then afterwards it no longer starts Any help would be appreciated, in florida dealing with hurricane and no Jeep

Good information Bro

Thanx u guys my jeep is now working I did it myself n it saved me a lot of money

thanks for the video my friend , I have a 2002 jeep gran Cherokee , there is no communication with my scanner, , no power to the coils nor the injectors, cranks but won't start, , can the skim cause this problem or its just the computer that is bad? thank you.

Wait wait wait…. So I just unplug the skim and I’m good?

What did you do to the pcm I couldn’t get that part !

Thanks man, thank you

Hi i got an xj jeep 95 model took motor harnes and trans i need to do an omni bypass or does it have a skim unit basically am looking for which wires will start the car on the 95 pcm

Had just one original key, so I copied couple of after market keys from, then I installed my original key close to skim module with cable tie and left the key there for ever, last thing was to put the plastic cover back to its place and the job was done, my Jeep is running perfect with any regular copied keys, this was 4 years ago, problem solved, no pc , battery, water tank, some bolt and so and so removal required, no dealer no locksmith no programing, cost me only 2 keys from Amazon.

What company did you go with

I have a question... I’m not experienced in mechanics... what should I be asking a mechanic specifically to determine if he/she can indeed complete this task❓

I'm hoping someone can help me out with some info.... I have a 2016 jeep compass and my dumb ass baby dad thought he would take this skim piece off and break it so I can't leave probl is my car is also hot wired because again my son's father did some other dumb shit. I can't buy this computer as I'm not working because I can't get to my job. Im in serious need of a car I live in the middle of no where so it'd not like I can walk I have a toddler who obviously has needs that only I take care of my life is a mess with out a car how can I fix this shit

Long term storage mode, pinch & pull, wait , pinch and push.

Wow, it’s a lot easier to get to the XJ PCM!

Dudes taking the whole car apart😂

I'm lost....so you are fitting another Ecu that has no immobiliser? Best regards

Security Key Imobilizer module S K I M

Well this might be a temporary solution take the battery terminals off both of them unplug skim code reader from underneath the steering column and pray or work

Hi I’ve got a commander and it run for a few seconds and stalled after trying to start a few times it seems to have locked me out it just clicks now no starter . I suspect the skim as done the battery relays starter motor ignition switch. Do you think I probably have to do skim delete?

I performed this procedure on my 2001 Jeep Grand cherokee. It now starts with the original key then dies after a few seconds. Any Ideas?

Excelent xplanation, thanks..

I'm having similar issues with my 2000 jeep grand cherokee limited so I just ordered a new computer and am going to do the same as you did in this video. You mentioned any issue with wiring or sensors can cause problems with the skim unit. My question is, if I replace the computer without the skim activated and whatever issue, wiring, sensor...whatever remains, will that cause the new computer to fail or is it all in the skim? Will deleting the skim keep my cherokee running even if there may be wiring or sensor issues? Funny thing is everything works as long as the engine isn't running. Once it's running that's when everything goes out and the key light comes on. No power windows, locks, gauges, etc... but when the engine is off but the key is turned on everything works fine. Thank you and great video.

Very nice video. Do you have any idea if this can be done with a 2009 pt cruiser? It looks like everything is the same. That would be nice if I could get it done to my pt. Right now I’m just troubleshooting it but I would definitely like to bypass the skim module. Thanks

Hi I changed the reader and computer box on jeep Cherokee ,if I program a new key will car start or must it be realign?

Interesting. Where do you get the new computer? Dodge dealer? Thumb up for the info.

Any issues of with the abs module? That’s my issue at the moment because I bought a ecu with the key and immobilizer but abs light stays on and was told that the abs module had to be programmed

Great video.

Also what you can do is when you're taking battery terminals off put the two battery terminals together do not have them connected to the battery and connect the positive and red together and make sure they're not touching the battery obviously don't blow anything up and hopefully they'll reset your PC you been there done that

I wonder would this same method work on my 2007 Jeep Wrangler JK 2.8 CRD??

Your awesome. We are thinking this could be our issue our jeep runs but sometimes it doesn’t start and then it sometimes it shuts down while I’m driving. We think we did everything else. Do you have any ideas why my jeep starts drives nice and eventually just stalls while driving there are days it won’t start for a while and then she does but shuts off before we move. Please give any ideas or advice. We feel it’s something pretty simple that we can do before we have to send it to a garage.

Thanks Ronnie

Hey so ive done this. Works great. But i locked my doors , unlocked with key cause i lost the fob, so now it starts and all but i got horn and 4ways going and it wont shut off how doni reset this ?

I know this is an old video, couldnt you have your original PCM re-flashed to not have SKIM?

Who do I get to reprogram the pcm with new vin

Îmi puteți spune și mie dacă va rog ce ia-ți făcut de a pornit în Romana va rog!

is it possible that the SKIM could cause transmission code to pop up on diagnostic machine

I have an 02 grand Cherokee I was having the same issues would start and stall with the security key on. Replaced the pcm and now it runs perfectly fine but my whole dash cluster is out. Any suggestions on what to check out or am I just hunting for a lose or broken ground somewhere. Thanks for any and all info

hello Ronnie, I watched your video on KZfaq about the SKIM module on a Grand Cherokee WJ 4 liter 7v 8. Unfortunately I am from France I understand English very poorly and the subtitles in the comments are not very accurate. Could you tell me by message what I should do to solve my problem with my skim module. so I can copy and paste your text to translate it. thank you

On dodges if you change the computer, immobilizer, and cluster and bring the other key over you will have no issues

brother i need help with my 02 jeep wj overland edition. i had an 04 that i totaled and i transferd over the 04 computer plus pcm plus my 04 ignition and engine. why wont this truck turn on?

Does this also apply to 1997 Dodge Ram 1500 as well?? I have a car that’s a crank/no start and doesn’t have a check engine lite either???? It has power at the ecm on the black plug @ pin #2 & 22.....

Is the TCM present in all WJ like Laredo? Or only higher end models?

Hi, My Ignition Key circuit is damage and rusty, can you share how to obtain a circuit for a 2005 Jeep Grand Cherokee Laredo 4.7L V8 without going to the Dealer? How does that Circuit works, to get the original for my car? I know I have to get it cut it and programming, but my concern is to get a new circuit? I truly appreciate it!

So did you replace it or did you just unplug it and take it out

If im just getting the ecm repaired do i still have to unplug the skim?
