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