Most newer Ford vehicles are equipped with a Passive Anti-Theft System (PATS). This system uses a transponder key embedded with a computer chip that sends a signal to the vehicle, allowing it to start. If an attempt is made to start the vehicle without the key, or if the wrong key is used, the engine will not start. While this system is effective at deterring theft, there may be times when you need to disable it. Here are some instructions on how to do so.
1. Locate the PATS module. This is usually found in the central junction box under the dash, but its location can vary depending on the make and model of your vehicle.
2. Disconnect the battery negative terminal for 30 seconds then reconnect it. This will reset all PATS parameters and disable the system.
3. Locate the two wires that go to pin 7 of the PATS module connector – these will be labeled “P” and “B” for programming and bypass, respectively. Cut or disconnect these wires then reconnect them together using a wire connector or splice them together with solder and electrical tape. This will bypass the PATS system entirely.
4. Start the vehicle and test drive it to make sure everything is working as it should be before taking it out on public roads
