Ford Enhanced (OBD II) Diagnostics
6
Erase Codes
Refer to “Erase Codes” on page 4-5 of Global OBDII Diagnostics. Perform
this KOEO. After erasing the DTCs, verify new ones have not been set using
the Read All DTC function.
Until all monitors have ran the absence of a Diagnostic Trouble
Code (DTC) does not mean the fault has been fixed.
View Data
The View Data function allows you to view the vehicle’s Parameter
Identification (PID) data in real time. As the computer monitors the vehicle, the
information is simultaneously transmitted to the scan tool. Apart from Read
Codes, View Data is the most useful diagnostic function for isolating the cause
of a vehicle driveability problem. View data is also used for observing sensor
data and the status of switches, solenoids, and relays.

Function List and press
ENTER
.
Ford arranges the PIDs in six groups:
❒ Standard Info: viewing of analog
sensor signals, such as
measured voltage from O2
sensors, temperature sensors,
and air flow sensors.
❒ O2 Sensor Info: viewing oxygen sensor information.
❒ Misfire Info: viewing of cylinder misfire information.
❒ Auto Trans Info: viewing of automatic transmission information.
❒ Man Trans Info: viewing of manual transmission information.
❒ A/C Info: viewing of air conditioning information.
After selecting a group, the scan tool
asks the vehicle to provide the PIDs it
supports for that group.
The scan tool displays a menu with
display options. Use the
UP/DOWN
to
select an option and press
ENTER
.
Refer to “Viewing Data” on page 3-11
to setup the data list.
