FORD COMPUTER SYSTEM OVERVIEW<br />
The Enhanced OBD2 & 1 Tool is compatible only with EEC-IV<br />
Computer Control systems.<br />
IMPORTANT: When the computer is in Self-Test mode (is<br />
testing the sensors or actuators for proper operation), it relies<br />
on voltage signals that is sends to and / or receives from the<br />
sensors or actuators to determine whether or not these<br />
components are operating properly. The sensors and<br />
actuators are all connected to the computer by wires. If any<br />
defects are present in any part of the circuit that connects<br />
these devices to the computer (such as defective connectors<br />
or wires, faulty grounds, improper voltage, shorts etc.), the<br />
voltage signal that the computer receives from these devices<br />
will be affected. The computer has no way of determining if<br />
the improper voltage signal is being caused by a defect in the<br />
circuit or by the sensors or actuators themselves. Keep this in<br />
mind when servicing fault codes, and do not replace any<br />
devices (sensors or actuators) before checking the complete<br />
circuit (or circuits) that are part of the device from which the<br />
code was generated.<br />
