The data link connector (DLC) contains the following:
| • | The UART serial data line (CKT 800) |
| - | The UART serial data line (CKT 800) allows the following
components to communicate data with each other: |
| • | The powertrain control module (PCM) |
| • | The inflatable restraint sensing and diagnostic module (SDM) |
| • | The electronic brake control module (EBCM) |
| • | The driver information display (DID) |
| - | The UART serial data line allows a scan tool to communicate with
these modules for diagnosis and testing. |
| • | The class 2 serial data line (CKT 1807) |
| | The class 2 serial data line allows a scan tool to communicate
with the PCM and pass key III module for diagnosis and testing. |
| • | The E+C serial data line (CKT 835) |
| | The E+C serial data line allows a scan tool to communicate with the
radio for diagnosis and testing. |
| • | Unswitched voltage (B+) (CKT 440) |
