Note: This procedure checks for an open circuit
or for a short circuit in the Data Link. If you are
experiencing faults in communications between the
electronic service tool and the Electronic Control
Module (ECM), refer to the Troubleshooting Guide,
“Electronic Service Tool Will Not Communic ate with
ECM” before this procedure is used.
The Data Link is the standard data link that is used by
the ECM to communicate with the electronic service
tool. The ECM communicates with the electronic
service tool in order to share status information and
diagnos tic information. The electronic service tool can
also be used to configure the ECM parameters. This
information will not be available if communication fails
between the ECM and the electronic service tool.
