Key Resistor Inputs

Key resistor inputs are used to determine if correct ignition key assembly is being used to start vehicle. Key resistor inputs are read only when theft deterrent module assembly is first turned on. If key code (resistance value) of ignition key assembly matches value stored in theft deterrent module assembly, theft deterrent relay assembly and fuel enable output will allow vehicle to start. If resistance value of ignition key assembly does not match value stored in theft deterrent module assembly, relay assembly and fuel enable output will not allow vehicle to start.
