Immobilizer System Operation: Ford Ranger Security System

The document describes the operation of a Ford Ranger vehicle security system. When the engine switch is turned to the ON position, the system uses a chip in the key to check if it matches the vehicle and decide whether to start the vehicle or not. If the key chip code does not match what the vehicle expects, it will prevent the vehicle from starting.
