I have a 2000 AU series II ute with smartshield issues. The car is immobilised and no-one seems to want to fix it up here (Ford dealer refused outright to even look at it, too old) so I have resorted to educating myself a bit to try to understand why one tiny piece of technology can hold my otherwise mechanically sound car to ransom. I have to say it seems the most ridiculous bit of kit!

I found information on the J3 chip and how it bypasses the smartshield system (perfect)and I contacted an auto electrician who said he would fit it for me but I am still not quite sure how it works. I emailed TI performance and asked them and the guy emailed back saying yes the chip will work, send me the catch code when you order but then I found a warning in the install guide that if the car is immobilised with the chip in it only ford can fix it (Ford wont!) which makes me wonder, if it is already immobilised what happens?

Can anyone tell me, if the car is already immobilised (red hand flashing fast on dashboard) will the J3 bypass the whole mess and let me start my car?

Thanks in advance, hope it all makes sense

No. The j3 will bypass smartshield, but it sounds like your PATS system is active. This can only be fixed with the correct scan tool.

Funnily enough, installation of a j3 onto my au2 xr8, caused the pats to come on and I had to get a mobile mech to fix it. There was only 1 in town that had the right tool. Cost me about 100 from memory. They need to be able to clear a pats code. This was what I remember from Jason at ti. Apparently I installed it wrong or something.

This is partially incorrect.

J3 Chip can disable the smartlock and smartshield imobilisation.

I cant remember 100% for AU, however you would still need to bypass the Smartshield unit for starter (join Wires), and possibly fuel pump as well so that the car can be started

The light may then flash on the dash, but the ECU will not stop your car from running. is able to help you, including providing a pre-programmed chip. You may have to join two jumpers on your ECU, or get help from someone who knows close to you. You will also have to clean the J3 connector.

The second alternative here is that you can send your ECU to a person in Sydney (Name is Nathan) - on FordForums. He is able to reprogram your ECU to not require PATS without the J3 chip.
