Circuit Description
The provision for communicating with the ECM is the Data Link Connector (DLC). It is located in the instrument panel
fuse block. The DLC is used to connect the scan tool. Battery power and ground is supplied for the scan tool through
the DLC. CAN line is used to communicate with the other module such as the Transmission Control Module (TCM) and
Transfer Case Control Unit (TCCU).
Keyword 2000 Serial Data Communications
Each bit of information can have one of two lengths: long or short. This allows vehicle wiring to be reduced by transmit-
ting and receiving multiple signals over a singles wire. The message carried on KWP 2000 data streams are also priori-
tized. If two messages attempt to establish communications on the data line at the same time, only the message with
higher prioritywill must wait.
