Gents,

I have been scouring the internet for hours to figure out the compatible PCMs for my '99. Is their some sort of documentation on this?

I looked in the archived threads and couldn't find ****.

Thanks in advance for any help.

 

I don't have that exact information, but I would sure think that the salvage yard would.

 

You'll have to specify what engine and transmission you have, whether it was originally an export, if your Jeep is Federal Emissions.

I can go to the parts catalog and look it up if I had this info.

What number is on your current PCM?

 

Thanks for the reply, sorry for the vagueness - new to this jeep thang. I have a 4.0L, automatic, 1999 Limited - i'm checking the VIN now for some more information.

Update: I don't see anything regarding Federal Emissions or it being an export.

This is what I see on the PCM P/N - P56041 :

That is the correct PCM for your '99, AW4, 4.0 L, Federal Emissions.

 

Yeah I called the salvage yard, they informed it I had to find the exact same. Doh.

 

Don't the 492AC gotta match also...

 

According to the salvage yard, yes.I'm not sure the differences, however. fml.

That's the one I am currently looking at. I don't like to put my trust into an ebay seller's hands, but I feel I am left without choice. It looks like they do offer a lifetime warranty, however.

 

Look locally to you for a place there are around ..Autoparts stores sell them even you seem to have the only one with ac on the end from what ive searched..

 

Exactly... it's some sort of super rare PCM. It must be Optimus Prime or some ****.

I ordered it. Tired of looking to be honest.

 

Good luck.

 

What's the part number of that POS on evilbay. I couldn't find it.

Get only a part number 492AC PCM. No other year carries this part number.

PCM's for 99 XJ

ERO = 4.0, DGO = Auto Trans

#56041 492AC 1 ER0 DG0 Federal
#56041 493AC 1 ER0 DG0 California
#56041 494AC 1 ER0 DG0 European

#56041 495AC 1 ER0 DG0 Leaded Fuel

 

It was a 492AC. They say they carry all off them (every year, every trim) for non-exports. I had to send them the part number and my VIN.
