Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
Engine coolant temperature | PCM | This message is sent to the GWM and then to the VDM. Indicates the current engine coolant temperature in degrees Celsius. |
Ignition status | BCM | This message is sent to the GWM and then to the VDM. Indicates the current ignition status; off, accessory, run, start, invalid or unknown. |
Odometer master value | IPC | This message is sent to the GWM and then to the VDM. Indicates the current odometer reading in kilometers. |
Stability control brake active | ABS module | Indicates the current ESC activity, on or off. |
Steering wheel angle | ABS module | Indicates the current steering wheel angle relative to the straight ahead position. Used to determine the amount of dampening required during vehicle operation. |
Traction control mode | ABS module | Indicates the current traction control activity, on or off. |
Vehicle configuration data | BCM | This message is sent to the GWM and then to the VDM. Indicates the current vehicle configuration and optional equipment. |
Vehicle lateral acceleration | RCM | Indicates the current lateral acceleration as measured by the sensors in the RCM. Used to determine the amount of dampening required during vehicle operation. |
Vehicle longitudinal acceleration | RCM | Indicates the current longitudinal acceleration as measured by the sensors in the RCM. Used to determine the amount of dampening required during vehicle operation. |
Vehicle roll rate | RCM | Indicates the current roll rate as measured by the sensors in the RCM. Used to determine the amount of dampening required during vehicle operation. |
Vehicle speed | PCM | This message is sent to the GWM and then to the VDM. Indicates the current vehicle speed in kilometers per hour. |
Vehicle yaw rate | RCM | Indicates the current yaw rate as measured by the sensors in the RCM. Used to determine the amount of dampening required during vehicle operation. |
Vehicle Dynamic Suspension
The VDM is connected to the HS-CAN to communicate with the ABS module, the RCM, the BCM and the PCM to monitor vehicle roll, pitch, cornering, braking and acceleration. Using the information received from other modules and the information from the 4 vehicle height sensors, the VDM calculates the best action for each of the 4 suspension dampers.
The driver is also able to select 1 of 4 preset system modes (Tour, Sport, Track or Drag) using the message center. When a mode is selected, the VDM regulates the magnetic field of the damper piston to keep the suspension "feel" relational to the selected mode.
When the VDM is initialized (ignition ON), it carries out a preliminary electrical check of the height sensors, height sensor circuits, damper piston electromagnetic coils and damper piston electromagnetic coil circuits. Any malfunction detected in the system causes the VDM to set a DTC and send a message over the HS-CAN2 to the GWM. The GWM relays this message to the IPC over the HS-CAN3 and the IPC responds by displaying a message in the message center.
Depending on the DTC present, the VDM may deactivate the dynamic suspension resulting in a firm suspension feel.
