Data Link Connector (DLC)
The data link connector (DLC) terminal 2 contains the
class 2 serial data link.
The DLC also provides a power source for the scan tool as follows:
| • | Battery voltage at the DLC terminal 16 (circuit 1440). |
| • | Ground at terminal 4 (circuit 150) and terminal 5
(circuit 451). |
Class 2 Serial Data Link
The class 2 serial data link allows the following modules to communicate
with each other:
| • | The body control module (BCM) |
| • | The electronic brake control module (EBCM) |
| • | The instrument panel cluster (IPC) |
| • | The powertrain control module (PCM) |
| • | The inflatable restraint sensing and diagnostic module (SDM) |
The class 2 serial data link allows a scan tool to communicate
with the above modules for diagnostic and testing purposes.
