FORD COMPUTER SYSTEM OVERVIEW
The OBD2 & 1 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 com-
ponents 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 affect-
ed. 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 (sen-
sors or actuators) before checking the complete circuit (or cir-
cuits) that are part of the device from which the code was
generated.
