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
transmitting and receiving multiple signals over a singles wire. The message carried on KWP 2000 data streams
are also prioritized. If two messages attempt to establish communications on the data line at the same time, only
the message with higher priority will must wait.
