The following modules may be accessed by a scan tool:
| • | The powertrain control module (PCM) |
| • | The sensing and diagnostic module (SDM) |
| • | The electronic brake control module (EBCM), if equipped |
The PCM is accessed through the data link connector (DLC)-OBD2 on the PPL/GRN wire at cavity 7 and the BLK/GRN wire at cavity 5. The SDM is accessed through the data link connector (DLC)-OBD2 on the PPL/GRN wire at cavity 7. The EBCM is accessed through the data link connector (DLC)-OBD2 on the PPL/WHT wire at cavity 2.
Even though programming of the remote control door lock receiver is provided at terminal 8 of the data link connector (DLC)-OBD2, there is no scan tool communication available.
Battery voltage is supplied to the DLC-OBD2 through the DOME fuse. Ground is provided to the DLC-OBD2 at G200.
These communication lines monitor the module for diagnostic purposes and in order to inspect for diagnostic trouble codes (DTCs).
