The Passive Anti-Theft System or PATS is an important security feature in the Ford Mustang. It is designed to prevent theft of the vehicle by disabling the engine when an unauthorized key is used. The PATS system uses a transponder key and a receiver module to communicate with the engine control module (ECM) or powertrain control module (PCM). In this article, we will discuss the wiring diagram for the 97 Mustang PATS system.
What is a Wiring Diagram?
A wiring diagram is a schematic representation of the electrical connections in a specific device or system. It shows how the various components are interconnected and how power and signals flow through the system. A wiring diagram is essential for troubleshooting and repairing electrical problems in a vehicle.
In the case of the 97 Mustang PATS system, the wiring diagram shows the connections between the PATS transceiver module, the ignition switch, the PCM, and other components involved in the system.
Components of the 97 Mustang PATS System
The 97 Mustang PATS system consists of the following components:
| Component | Description |
|---|---|
| PATS transceiver module | Receives the signal from the transponder key |
| Ignition switch | Provides power to the PATS system and the PCM |
| PCM | Controls the engine operation based on the signals from the PATS system |
| Transponder key | Contains a unique code that is transmitted to the PATS system |
Wiring Diagram for the 97 Mustang PATS System
The following is the wiring diagram for the 97 Mustang PATS system:
As you can see from the diagram, the PATS transceiver module is connected to the ignition switch, the PCM, and other components. The transponder key sends a signal to the PATS transceiver module, which then sends a coded signal to the PCM. The PCM compares the signal with the stored code and determines whether the key is authorized. If the key is authorized, the PCM allows the engine to start. If the key is not authorized, the PCM disables the engine.
