99 explorer pats bypass

Hi; Started to install a Remote Starter in a 99 Explorer with PATS. I was trying to locate the factoy disarm wire but couldnt. Now the car wont start at all. I have 65psi of fuel and I have spark. I think the PATS anti theft system is stuck. I have checked all the fuses and they are all good. Is there a way to bypass the PATS? Where is the module located at and can I just remove it? Thanks for any advice. Pat

you cant remove the pats system. You can bypass it, with a resistor but what is your real problem. does it crank? or crank but does not start. the factory disarm should have nothing to do with starting.

Thanks for the help. It cranks but does not start. I believe it uses a transponder. There is a black plastic ring with a module that fits over the key cylinder. It has 4 wires that hooks up to a white connector under the steering column. Before I ran into problems I was checking out this connector. With no key in the ignition, all four wires showed ground. When key inserted and in run position, one wire was ground and other three where hot. I attempted to jump the three wires with hot and see if the vehicle would then start without the key in the ignition. it would not. Then i put everything back together and it still would not start. I think I may have fried it so I will try to replace it and see what happens. Any idea what type of bypass unit I will need for this vehicle? If I have to replace the PATS module, any idea where it is located? Thanks for any help Pat

Replaced the transponder on the Ignition cylinder. Still wont start. Guess I will have to look for the module and see if that is what is causing me the problem.

One of them should of showed ground because it is ground.  Another one should show ignition which probably means that a fuse went out which probably cause it not to turn on the car.  The remaining two wires are the TX and RX and as far as I know you should NEVER jump these wires.  Chances were that the fuse was bad and thats why it didt turn on but now that you jumped the TX and RX im pretty sure you fried the transponder system.  You may need to replace the module and get the dealer to program new keys for system with their diagnostic tools.

I shorted one of these wires once and it was just a fuse. not sure which one but an easy enough recheck. you need a bypass or a spare key and a relay to bypass the transponder when you get it all back together workingThe greatest revenge is living well and showing it

Your the one who asked about T-Taps ....did you install this explorer with them? For pats you need to use a bypass module such as a xk04 from DEI with PKFORD firmware. You should only need one key to program unit. unplug harness starting from left to right looking at plug pin 1 of plug is ground pin 2 of plug is ignition pin 3 of plug is RX pin 4 of plug is TX You can not use resistors for pats, only vats and passlock I and passlock II in older GM vehicles yes.The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.

Do it right the first time... or I might have to fix it for ya

Your right...I screwed up and I learned from it. Now I am trying to fix it. It is not a customers car and I have another like vehicle to get parts from. I am just now trying to figure out where the components are located in the vehicle. According to All-Data, the module is on the right side IP. I found what I think is the module. It is white with a ten pin connector(2 rows of five) that is mounted on top of the ac/heater box. It matches what AllData shows. I will swap out the module from the other vehicle I have. It wont match the original key, but I am thinking if I dont attach the transponder to the ignition cylinder, I can place the key for this second vehicle in the center of the loop and see if the vehicle will start. If so, then I will mount everything as it should be and have the vehicle programmed and move on. As far as the t-taps go, I have ordered them, but have not yet received them. Thanks for the info on the bypass module I need. I know I must sound "Not To Bright" for making this type of screw up. I have installed 5 of these remote starts over the years before and never had a problem. I also never had any help other than the instructions. I have never encountered a PATS vehicle before though. All I can say is you live and learn. Currently we use All-Data in the shop. Is there a better online program for wiring remote starts (hopefully with pics:-))? Thanks again for the advice Pat
