PSCM Network Input Messages
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| ABS active | ABS | Used to confirm the operational state of the ABS. |
| Ignition status | BCM | This message is first sent to the GWM and then to the PSCM. Used to confirm the ignition status of the vehicle. |
| Power pack status | PCM | This message is first sent to the GWM and then to the PSCM. Used to confirm the status of the operating mode; off - torque not available, on - torque not available, start in progress - torque not available or on - torque available. |
| Power system status | BCM | This message is first sent to the GWM and then to the PSCM. Used to confirm the status of the vehicle battery and charging system. |
| Stability control brake active | ABS | Used to confirm the operational state of the stability control system. |
| Steering wheel angle | ABS | Used to verify the validity of the steering angle sensor. |
| Traction control brake active | ABS | Used to confirm the operational state of the traction control system. |
| Vehicle configuration information | BCM | This message is first sent to the GWM and then to the PSCM. Used to compare the PSCM configuration against the vehicles specific configuration (central car configuration). |
| Vehicle lateral acceleration | ABS | Used by the PSCM for steering assist calculations. |
| Vehicle lateral acceleration | RCM | Used by the PSCM for steering assist calculations. |
| Vehicle longitudinal acceleration | ABS | Used by the PSCM for steering assist calculations. |
| Vehicle speed data | ABS | Used to determine the level of assist supplied to the steering gear and to validate the steering wheel component angle by comparing the rotational speeds of each wheel. The difference in the speed of each wheel is used to derive a steering angle for comparison against the EPAS motor position sensor. |
| Vehicle yaw rate | ABS | Used by the PSCM for steering assist calculations. |
