1994 Ford Taurus V6-182 3.0L DOHC SHOSECTION Description and Operation
PURPOSE
The data link connector provides an input and output path to the Powertrain Control Module (PCM). This allows for the following functions:

PCM Serial Data
Through the use of a scan tool information concerning sensor input values and PCM outputs can be directly accessed.

Diagnostic Trouble Codes
Diagnostic trouble codes may be retrieved or cleared with the use of a scan tool or manually with the use of a high impedance analog voltmeter.

Self-Tests
Initiation of the self-test features of the PCM can be performed manually or with the use of a scan tool.

CONSTRUCTION
The data link connector is composed of two connectors. The larger connection is a 6 terminal connector used to provide access to the PCM. The smaller connection is a single pigtail connector which is used to ground terminals on the 6 terminal connector when initiating self-tests or accessing diagnostic trouble codes.
