New to forum
My 2001 3.0 2wd randomly refused to start so now its stranded in a parking lot.

When key is turned to start the theft light on dash blinks rapidly.

Brand new battery.

Tried striking starter, nothing
Tried disconnecting battery to reset Pats/computer

Checked pcm relay

Is there anything else as far as fuses/relays I should check? Any battery disconnect trick? Anything? Should I get it towed to a dealer?

I'm stumped and I need this truck to run asap

Any help would be greatly appreciated

 

Welcome to the forum

Can't reset PATS, after 3 tries using the key it will be in Lock Down for 30-45min, even with battery unhooked

Fuse #19 in the cab fuse panel, 25amp, is the only fuse for PATS, it also powers the spark coil pack and PCM relay

You need to get the PATS Code number to find out whats wrong, which is easy to do
Turn on the key
Theft light will flash rapidly for 60 seconds, THEN it will start to flash a code number

two digits always starting with 1

so 1 flash, pause, 1 flash, longer pause, then repeat for code 1:1
1:2
1:3
1:4
ect......just count the flashes


Google: Ford PATS code "Number"

Or post it here

PATS codes can also be read with "most" OBD2 readers, but they will be "B" codes, they will start with B, like engine/transmission codes start with P, B is for a Body code number
Bxxxx
So 4 digits after the B

Most common is the transceiver has failed, the ring around the key slot, not hard to change

If its your only PATS key and its not working then you will need a Mobile Locksmith(better than Ford dealer) to come out to make a new key and add it to the system, I would suggest getting 3 keys but up to you
Locksmith can't help you if its a bad transceiver, or wiring issue


There is no by-pass for PATS, tow it or fix it where it sits are the only options

 

Thanks RonD

So it looks to me that the code is showing 1:1

 

That's a transceiver code

I would pick one up at wrecking yard, 2001-2005 part number is 1L5T-15607-AE
Used in Ranger, Mazda B-series and Explorers those years

You will need to pull off steering column covers, and lower dash covers to change it

Its a 4 wire plug in make sure old one's plug is OK, and wires
1 wire is 12v Key ON, from fuse 19, red wire
1 wire is a Ground, black wire
Other 2 wires send the Key's Code number to PATS in the Computer, grey and white wires

You should test 12v and ground

You are swapping it out, the above was a new install

 

Ok cool, thanks so much for your help

I ordered a new transceiver and I should have it tomorrow

I'll replace the old one and post my results

Thanks again

Ok so I haven't got the new transceiver yet
But I had a chance to test the wiring with a multimeter

I removed the old transceiver completely, turned the key to the on position and tested the female end of the 4 wire harness plug

The red 12v wire read 0

I dont have a black wire so I'm assuming the the green wire I have is the ground..

The green wire read 12.6

So will have to trace the red wire to find a break?
I'm not very savvy with wiring/electrical issues so please excuse my ignorance

Also my new transceiver should arrive in the mail tomorrow..

Just wondering if since my red wire isn't reading then it's a deeper problem?

Thanks

 

Ford did use a green wire for 12v on some years, so that may be OK


What are the other 2 wires colors?
Green
Red
??
??

 

The other two wires are blue and white

I got a 12.6 reading on the blue

So I have a power to the blue and green wires, the other two nothing.

Looking at plug, the wires are in this order..

Blue - White
Red - Green

Thanks again

 

And that's the Truck side wire colors?

I have no wiring diagrams from 1999 to 2003 that match those colors for PATS Transceiver?

 

yes that is the truck side

Now that I think about it, i had a breathalyzer interlock installed on my truck a couple years ago..

I wonder if they could have replaced OEM wires or harness?

 

Yes, that would be a good place to install something like that, simple relay to cut power to transceiver would disable startup

But can't say thats what "they" did

Ok I received the transceiver in mail today and I will install when I get home from work

I have another question though..

Is there anyway I can test the starter with the Pats engaged?

Also I can put the truck into neutral, if the the Pats is the problem I shouldn't be able to shift right?

 

Just installed the new transceiver

Truck started RIGHT UP! 😀

Cant thank you enough RonD

You da man!

 

Good work

Thanks for the update and hopefully THE FIX

You can jump a starter motor with a 12v wire from battery, to the "S" post on starter motor, the smaller wire's post on starter
This tests if starter is working, but PATS would still prevent start up

No, PATS doesn't prevent shifter from moving, it disables fuel pump and fuel injectors, and starter motor on most years, but not all
