- Summary
- SM2201 Ford 7.3L PATS Module Familiarization PATS Immobilizer Module: Purpose, Functionality, and Troubleshooting The PATS (Passive Anti-Theft System) or SPM (Security PATS Module) is a new piece of required hardware that has not been used historically on Ford powered Blue Bird Vision Buses. The intent of this memo is to provide a basic overview of its function, purpose, and basic diagnostics. The 7.3L PCM hardware requires a PATS handshake to enable engine crank. The PATS module, sometimes called an SPM, is paralleled to Ford CAN only and not to J1939. It’s mounted above the MPX module (non-NEA) within the PDU and on NEA models it is located on the ledge above the chassis PCB. The PATS module is purpose built for non-Ford VIN applications using the 7.3L engine. It is paired to the PCM via an IDS bi-directional function, to which one needs Ford PTS log in credentials for IDS access to the immobilizer database.
