CONNECTING THE SCAN TOOL
The scan tool's Ford Connector Cable Adaptor is designed to
match the vehicle's computer DLC. When properly connected,
the vehicle's DLC should match the pre-molded guides around
the adaptor. Make sure the adaptor and the vehicle's DLC
mate properly before applying force. Forcing the adaptor onto
the DLC improperly may result in damage to the adaptor
and/or scan tool, and possible damage to the vehicle's
computer system.
Connect the scan tool to BOTH.
1. large, six pin female connector with

2. small, single pin female connector
1988 and newer vehicles

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.
DIAGNOSTIC TROUBLE CODES (DTCs)
Diagnostic Trouble Codes, or Fault Codes, can be used to identify
engine systems or components that are malfunctioning. The computer
records codes for two types of problems:
"Hard" Diagnostic Trouble Codes
"Hard" DTCs represent problems which are happening now and
cause the instrument panel Malfunction Indicator Lamp (MIL) or
Check engine light to illuminate and remain on until the failure is
repaired. A DTC is stored in the vehicle's computer memory for
each fault detected. A Scan Tool or Scanner can be used to retrieve
DTCs that are stored in the vehicle's computer memory.
Intermittent/History DTCs
Intermittent/History DTCs are stored in the computer's memory for
problems that occur intermittently, or for problems that happened in
the past but are not currently present. Intermittent DTCs may cause
the Malfunction Indicator light to flicker or stay on until the
intermittent malfunction goes away. However, the corresponding
