Battery positive voltage (B+) is provided from the ALDL fuse in the Rear Junction Block on CKT 3640 (ORN) to the Data Link Connector at terminal 16. The ground reference for the scan tool is supplied at the DLC terminal 5 on CKT 351 (BLK/WHT) and DLC terminal 4 on CKT 450 (BLK). The Class 2 Serial Data Line CKT 1807 (PPL) is wired to the DLC at terminal 2 and the CKT 800 (TAN) connects DLC terminal 2 to the Continuously Variable Road Sensing Suspension (CVRSS) module.

| • | Cellular Telephone Docking Station |
| • | Dash Integration Module (DIM) |
| • | Electronic Brake and Traction Control Module (EBTCM) |
| • | Instrument Panel Cluster (IPC) |
| • | Instrument Panel Integration Module (IPM) |
| • | LH Front Door Module (LFDM) |
| • | Memory Seat Module (MSM) |
| • | Navigation System (Japan export option) |
| • | Powertrain Control Module (PCM) |
| • | Radio (IRC) |
| • | Radio Amplifier (AMP) |
| • | Remote Function Actuator (RFA) Module |
| • | Rear Integration Module (RIM) |
| • | Road Sensing Continuously Variable Road Sensing Suspension (CVRSS) Module |
| • | Sensing and Diagnostic Module (SDM) |
| • | Steering Column Tilt/Telescoping Module (TTM) |
| • | PASS-Key®III Module (VTD) |
Loss of Class 2 Serial Data DTCs Matrix
The following charts represent a complete matrix of all Loss of Class 2 Serial Data DTCs. Use these charts as follows:
| • | The top row of each chart indicates which module has lost Class 2 communications. |
| • | The left column of each chart indicates which module observed this Loss of Class 2 Serial Data, and internally set a DTC to identify this condition. |

Simple Bus Interface (SBI) Serial Data Line
The Simple Bus Interface is used for serial data communication between the four door modules as well as the LH Front Power Window Switch. Electrical input and output devices within the doors are wired to the corresponding door modules; the power door locks, power windows, power mirrors, jamb switches, and cylinder switches are all controlled this way.
