Class 2 Serial Data Link
The Class 2 serial data link allows these modules to communicate
data with each other:
| • | Body Control Module (BCM) |
| • | Driver Information Display Module |
| • | Driver Seat Adjuster Memory Module |
| • | Electronic Brake Control Module (EBCM) |
| • | Inflatable Restraint Sensing and Diagnostic Module (SDM) |
| • | Powertrain Control Module (PCM) / Vehicle Control Module (VCM) |
| • | Transfer Case Shift Control Module |
| • | Vehicle Interface Unit (VIU) |
In addition, the Class 2 serial data link allows a scan tool
to communicate with these modules for diagnostic and testing purposes. The
Class 2 serial data link is located at the DLC connector.
