DCL Data Functions (EEC-IV Vehicles)
DCL (Data Communication Link) Data functions are used to view and record
engine data transmitted from the vehicle on EEC-IV vehicles beginning in 1990.
These functions allow viewing of data parameters in real time to pinpoint prob-
lems when they occur. The tool also has the ability to record these data param-
eters as the vehicle is operated to locate intermittent problems.
To view DCL Data Functions, select DCL
Data from the
Ford Function List.
The tool displays the DCL Function
List. Select View Data and press
ENTER
.
View Data
The View Data function allows the mechanic to view PIDs in real time. Simply
stated, as the PCM monitors the vehicles PIDs, they are simultaneously trans-
mitted to the scan tool. Viewing data is also used for observing sensor data and
the ON/OFF state of switches, solenoids, and relays.
After selecting View Data, a Select Data
to View screen will allow you to custom-
ize the function. See “Viewing Data” on
page 3-9 of Using The Scan Tool for
Entire or Custom Data Lists.
After selecting the Entire Data List or Custom Data List, press
ENTER
.
Once the communication link has been established, start the engine and let idle.
The tool displays either the Entire or Custom Data List, depending on the pre-
vious selections. A Vehicle Data List header marks the beginning of the data list.
Use the
UP/DOWN
arrow keys to scroll through the PIDs.
If the Custom Data List parameters need to be changed, press the
BACK
key
at any time. This returns the tool to the Custom Data List display.
When done, press
BACK
twice to return to the
DCL Function List or press
FUNC
to return to the
Ford Function List.
Record Data
The Record Data function is used to record vehicle data parameters over time.
The Record Data function allows diagnosis of an intermittent problem by ana-
lyzing data leading up to the problem, during the problem, and possibly after the
problem, depending on duration. This function is used if no other diagnostic
method works.
The tool records data based on time (5 frames prior to the trigger point, and for
a duration after). The time after depends on the vehicle data rate.
