PCM Location?

[CobraLS]

Anyone know off hand where the PCM is located in a 2003 LS with the V8?

Its located behind the glove box!

Thanks.

are you trying to remove it or looking for the code?

I picked up my LS today and the dealer didn't know the door keypad code. The owners manual says it is written on the PCM sticker.

Do a search; this has been discussed several times. We've all looked, and none of us have found this mythical sticker. The only way to get it is with the dealer's diagnostic equipment.

Please let us know what you find!

Sooner...do you suppose that maybe we can't recognize where they have it on the sticker? I don't know how to ask what I mean by that. Say...it's part of another number...like the last four digits or something?

 

[CobraLS]

I will take a look on the PCM and see if I find anything. I will also write down all of the numbers on the PCM. If I cannot find the code I will take it to the dealer and get it read, then compare it to the numbers off the PCM.

I looked on the PCM and tried some of the number on there. Either none of them are the proper numbers or the code has been changed by a previous owner. Off to the dealer it goes to get the code.

Users cannot change or delete the factory code. It is always valid. This may sound stupid but did you try looking in the owner's manual package? There was a card in mine with the code on it.

No owners manual or card came with the car. So even if a previous owner added a personal code, the factory one remains intact? If so, maybe I will pull the PCM and see if it is on there in a location I cannot see.

I got the code read at the dealer today. The code does not match any of the numbers on the PCM that are in view. I will still pull the pcm and check it is some else on it once the weather warms up......IN MAY!

That's certainly possible, but the Owner's Guide does, in fact, tell you that you can find it "on the computer" (without defining which of the LS's modules it's defining as "the computer"). Given that, it doesn't make any sense for them to "encode" the number.

The DDM does have a "paper" tag that looks like it might have had the code on it, but so far, everyone who's looked at it (including me) has seen that the tag was torn off. Someone reported that they do this on the assembly line (as instructed, not out of cussedness). I haven't checked the DDM in my '06, but I bought it new, so I got the card with the code in the Owner's Guide packet, and haven't bothered looking.

I dont know if this is relivant, but on my wife's previous car (crown Vic) the dealer could not find the sticker w/the code, so plugging in was the only option (I did not want to pay). Anyway months later I found it on a module behind the driver's side door panel while replacing speakers. The module had the code clearly posted. My F-150 by contrast had it on the module under the dash on the firewall near the top of the gas pedal (nearly impossible to see, but visable nontheless).
