NOTE: 1988 and newer vehicles
may have more than one similar
connector for other systems (i.e.
Anti-Lock Brakes), only the
connector with an extra single
pin is the correct test connector
for computer service codes use. If
you have any questions about the
correct connector please refer to
your vehicle's service manual for
detailed information.
For the MCU System (most
vehicles built between 1981-
1983) connect the Code
Reader to the six pin female
connector only.
Optional Extension Cable
For one person operation, a 6'
optional extension cable for test
connection is available through your
local store or service department.
The extension cable allows you to do
all the code reading without the help
of another person.
FUNCTIONS OF THE FORD CODE READER
The Ford Digital Code Reader is a diagnostic tool that is
specially designed to connect to the vehicle's test Connector(s)
to communicate with the vehicle's computer.
The Code Reader does not generate codes. The Code Reader
serves as a "key" that links to, and opens communication with
the vehicle's computer to prompt the computer to perform Self
Tests, and to receive test results or retrieve codes.
