Where is the PATS Information stored in a 2010 F150 XL?

 

In the PCM

Thank you for this information! I read the pdf and it had a reference to Motorcraft Service to identify the PATS type code. However the chart was for years 1996-2007 only. Without the type code the information in the pdf you quoted can't be used.

How Does One Determine The PATS Type Code?

 

What exactly are you trying to accomplish?

My truck started random No Crank/No Start problem about 8 weeks ago. I replaced the lock cylinder, the transponder and ignition switch...no joy. So I purchased a rebuilt PCM/ECM/ECU and the locksmith could not program the transponder keys. Still no joy.

Then the company that sold me the rebuilt PCM/ECM/ECU told me the transponder keys weren't stored in the PCM/ECM/ECU. The locksmith told me it was usually the Instrument Cluster was bad when he had the problems trying to program my transponder keys. A couple of Ford Dealerships told me the transponder key information was stored in the transponder. Another Ford Dealership told me there was a separate module for the PATS Control.

So I took my dash apart until I was positive there was no separate PATS Control Module. As a computer programmer and licensed electrician, I am convinced the transponder does not store any information. And I am 99.9999999% certain the company that sold me the rebuilt PCM/ECM/ECU was wrong about the PATS Control and storage not being in the PCM/ECM/ECU.

So I'm in that proverbial rock and a hard spot. A previous reply told me the PATS Control is in the PCM and provided a reference for programming the transponder keys. But the reference only covered the years 1996-2007.

At this point I am consider buying a Key Programmer. I don't want to install a PATS Bypass Kit.

As an aside the acronyms have been confusing as PCM can mean Powertrain Control Module but also PATS Control Module.

Thanks for your interest in my project!

On a Ford PCM indeed stands for Powertrain Control Module. The PATS is Passive Anti theft System and is usually it's own separate module. If your truck was one year newer I could better help with your concern. I left the dealer in 04 so the only diagnostic disks I have are 96-99, 04-05 and the one I have for my own truck 2013 which contains info that applies back to 2011 for most things.

My guess and it is just that a guess, is the rebuilt pcm wasn't programmed with your trucks asbuilt data. For that you will need to head to the dealer for them to hook up IDS.

Your knowledge of computers and electrical/electronics might help but It's an entirely different animal as you are dealing with a multiplexed network of modules that transmit information over a high speed and medium speed controller area network. For communication with that network you need special equipment aka (IDS)

Yes you drive a rolling multiplexed network of computers and they all talk to each other to make the whole system work as one.

This is what the dealer uses.



I bought the system when I bought my truck because I knew without it I couldn't diag my truck when a problem might arise.

You can buy it as well but be warned, it's nothing close to cheap. I paid $2,200 for the equipment that came with a 1yr license. Licences now cost over $800/yr. You own the equipment once purchased, it's the software you have to pay to use.

That might work if he was dealing with OEM modules. He stated he purchased a reman PCM so if they didn't program his asbuilt data he's looking at an expensive lawn ornament. I don't know for sure if PCM asbuilt can be programmed with Forscan.

Thanks for the info. I was reviewing forscan. So that's what I'll do.
