Quick Answer
Quick answer: The 2002 Ford Mustang relies on the Passive Anti-Theft System (PATS) to help prevent unauthorized starting. For issues related to this system, understanding the fuses and modules involved is key.
- PATS Fuse: Typically, the PATS or Anti-theft fuse is located in the fuse box under the hood or dash. It might be labeled under something related to 'anti-theft' or 'PATS'.
- PCM Module: The Powertrain Control Module (PCM) communicates with the PATS to allow engine starting when the correct key is used.
- Transceiver Module: Found around the ignition area, it reads the signal from your key's chip to verify it's authorized.
For troubleshooting, check the relevant fuses to ensure they are not blown and ensure all electrical connections and modules are in working order. This might involve checking their condition or reseating connectors if necessary.
If you’re still having problems related to the PATS system, double-check these components and related wiring for any signs of damage or poor connections.

If you’re dealing with issues related to the PATS (Passive Anti-Theft System) on a 2002 Ford Mustang, understanding the fuses and modules involved is crucial for troubleshooting. Let's dive into where you can find these components and how they’re laid out.
Fuse Box Location
For the 2002 Ford Mustang, you have two main fuse boxes you'll want to check:
- Passenger Compartment Fuse Box: Located in the driver’s side under the dash. You should be able to access this by removing the panel cover.
- Power Distribution Box: Found in the engine compartment. This box contains high-current fuses that help protect your vehicle's main electrical systems.
Fuse Box Diagram and Table
Below is a simplified table highlighting key fuses related to the PATS system and other important circuits in your Mustang. Keep in mind that the numbering and assignment might differ slightly based on your vehicle's trim package and options.
| Fuse Number | Amperage | Protected Circuit |
|---|---|---|
| F2.34 | 20A | PATS, ECU and Ignition System |
| F2.18 | 30A | Ignition Switch |
| F2.13 | 10A | Diagnostic Connector |
| F1.5 | 50A | Main Fuse Block |
Modules Involved in PATS
The PATS system in your Mustang uses several modules to operate effectively:
- PATS Module: This is typically integrated with the car’s ECU, and it communicates with the transponder in your key.
- ECU (Engine Control Unit): It receives input from the PATS module and determines whether the vehicle should start.
- Key Transponder: Each key is uniquely coded, and the PATS system uses this code to either allow the engine to crank or to disable it.
Troubleshooting Tips
If your Mustang is having trouble starting and you suspect the PATS system, here are some steps to follow:
- Check all relevant fuses in both the passenger compartment and the power distribution box.
- Ensure your key is not damaged. Try using a spare if available to rule out key issues.
- If you recently replaced the battery, ensure all electrical connections are tight and corrosion-free.
- Observe for flashing security lights; this can indicate an issue with the PATS system.
Conclusion
By understanding where the fuses and modules related to the PATS system are located in your 2002 Ford Mustang, you can better diagnose and address any issues you encounter. Having a grasp of these components will empower you to handle minor repairs and understand your vehicle better.
