PCM Module Network Input Messages
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| Vehicle yaw rate | RCM | The PCM uses lateral acceleration and yaw rate information for the four-wheel drive system to determine percentage of torque to be transferred to the rear wheels. |
| Vehicle longitudinal acceleration | RCM | Provides the AWD system with longitudinal acceleration data via the HS-CAN. Data is used by the PCM in determining AWD system operation. |
| Vehicle lateral acceleration | RCM | Provides the AWD system with lateral acceleration data via the HS-CAN. Data is used by the PCM in determining AWD system operation. |
| Wheel speed data | ABS module | The PCM uses wheel speed information for the four-wheel drive system to determine percentage of torque to be transferred to the rear wheels. |
| Steering wheel component angle | ABS module | Provides the AWD system with steering wheel angle data via the HS-CAN. Data is used by the PCM in determining AWD system operation. |
| ePRNDL mode | IPC | Provides the AWD system with gear selector mode via the HS-CAN. Data is used by the PCM in determining AWD system operation. |
| Accelerator pedal position | PCM | The PCM uses pedal information for the four-wheel drive system to determine percentage of torque to be transferred to the rear wheels. |
| Engine RPM | PCM | The PCM provides engine RPM (revolutions per minute) data via the HS-CAN. Data is used by the AWD system to help determine torque application. |
