PCM for 2003 GC Laredo 4.7

I am looking for a PCM for my 2003 Jeep Grand Cherokee Laredo 4.7 V8.
There would be a slight logistical issue to sort out as I am in South Africa, but does anyone have one spare for my Jeep that you want to sell ?

Chrysler Part # p56041836ae

(I guess PayPal + Fedex would resolve most of these though ...)

Your number doesn't match our US part numbers.Also if you change the pcm you have to have a dealer program your key to the new unit or it will not run.

I know the pcm/keys need programming and will have that sorted out at a local dealer.

Is it possible that the part # does not match ? Where else would it come from ? Is that part # at least a PCM # ?

Re: PCM for 2003 GC Laredo 4.7

Is your jeep maybe an European build WG? I dont know why, but they use for several, the same, items different P/Ns compared to American build WJs and European build WGs. Dont know about the compatibility.
The P/N you gave is indeed the PCM, i found one in Denmark. Eventhough they have the option for English on that site, the translation doesnt work very well: http://www.ditonet.dk/index.asp?id=79&modelId=1151

Re: PCM for 2003 GC Laredo 4.7

Maybe a dealer could run the VIN for you. I'd hate to see you get a pcm that wouldn't work for you.

Re: PCM for 2003 GC Laredo 4.7

On my WG i still have a placard on the drivers door where is mentioned the place of build, date and all kind of other info. Brazilian Jeeps are build in Austria (at least mine is), so it could be that yours is too.
The next site has refurbished PCMs. Quite expensive though. They can also rebuild your PCM: http://www.autotekcarparts.com/index.php?Page=PopupPart&PartNumber=&PartID=30780& &lang=US
What is in fact the reason that you have to change the PCM?

When trying to start my Jeep, it only cranks and then after a few seconds a key with a cross through it appears on the dash.

I had the car towed to a dealer who diagnosed it as the PCM, but a new one is just way to expensive for me, hence looking for another one.

Apparently the PCM does not send the signals to the SKIM module anymore to deactivate the immobilizer.

Re: PCM for 2003 GC Laredo 4.7

Did you already try cleaning all connectors on the PCM? That company which i showed the site on my last reply, they charge 80 USD for a check and small repair on the PCM.
There is also a possibility of the SKIS delete. One of the members overhere did it.

I cleaned the connectors on the Skim module. I hope the dealers would have done the same for the PCM.

Do you have more info on the skis delete ?

I found the other thread on SKIS delete. The local dealer never mentioned anything about that, but I guess if the PCM is damaged then it will not make a difference whether the SKIS is present or not.
