Data Link Connector (DLC)
The DLC connection is the central location for communicating with all modules
that communicate using a serial data link. The DLC provides a power source and
a standard connection for the scan tool.
Refer to
Data Link Connector Schematics
for circuit information.
Class 2 Serial Data Link
The class 2 serial data link allows a scan tool to communicate with
the listed modules for diagnostic and testing purposes. The class 2 serial
data link is located at the DLC connector terminal 2.
| • | Driver Information Center (DIC) |
| • | Electronic Brake Control Module (EBCM) |
| • | Instrument Cluster (IPC) |
| • | Inflatable Restraint Sensing and Diagnostic Module (SDM) |
| • | Memory Seat Module (MSM) |
| • | Powertrain Control Module (PCM) |
| • | Theft Deterrent Control Module |
| • | Vehicle Interface Unit (VIU) if equipped |
The class 2 serial data link may also be connected to the Video Disc
Player and Rear Video/Audio/HVAC Module if equipped. However the Video Disc Player
and Rear Video/Audio/HVAC Module will not communicate with the scan tool, do not set
DTCs and other modules do not set DTCs against them.
