Module Network Input Messages - VDM

Broadcast Message	Originating Module	Message Purpose
ABS active	ABS module	Indicates the current ABS activity, on or off.
Accelerator pedal position	PCM	Indicates the current accelerator pedal position in percentage of travel with 0% at rest and 100% at full throttle.
Ambient air temperature	HVAC module	Indicates the current ambient air temperature in degrees Celsius.
Brake torque request	ABS module	This message indicates the total amount of braking, in newton meters, requested by the driver (via the brake pedal), the adaptive cruise control system or the collision avoidance system. The VDM adjusts the valve solenoids to help stabilize the vehicle during the operation of those systems.
Driven wheel torque request	PCM	Torque at the wheels (sum of all wheels) desired from the propulsion system. This includes the effects of the driver's accelerator pedal input and the effects of the virual driver functions, cruise control, adaptive cruise control.
Fuel level	IPC	This message is sent to the GWM and then to the VDM. Indicates the fuel level at time of ride height calibration in fractions of the fuel tank. The VDM uses fuel level when calculating suspension settings and uses a default setting when the information is not available.
Gear lever position	PCM	Indicates the current transmission gear status.
Gross train weight estimate	PCM	Rough estimate of the combined mass of a road vehicle, the passengers and cargo in the tow vehicle, plus the mass of the trailer and cargo in the trailer.
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.
Life cycle mode	BCM	This message is sent to the GWM and then to the VDM. Indicates the current vehicle life cycle; normal, factory, not used or transport.
Odometer master value	IPC	This message is sent to the GWM and then to the VDM. Indicates the current odometer value in kilometers and whether the data is fresh or unchanged.
Power pack status	PCM	Indicates the current status of the engine and powertrain; Off - torque not available, On - torque not available, start in progress - torque not available or On - torque available.
Selectable Drive Modes mode request	ABS	Indicates the current SDM mode.
Stability control event in progress	ABS module	Indicates a stability control system (traction control or ESC) is currently active.
Stability control indicator request	ABS module	Indicates the current stability control warning indicator status; on, off, slow flash or fast flash.
Stability control	ABS module	Indicates if ESC is available, yes or no, and active, yes or no.
Start stop status	PCM	Indicates the current start/stop status of the engine.
Steering angle data	PSCM	Indicates the current steering wheel angle relative to the straight ahead position.
Traction control	ABS module	Indicates the current traction control state, active or inactive and if it is active, yes or no.
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	ABS module	Indicates the current lateral acceleration of the vehicle in meters per second squared as measured by the sensors in the RCM and relayed by the ABS module.
Vehicle lateral acceleration	RCM	Indicates the current lateral acceleration of the vehicle in meters per second squared as measured by the sensors in the RCM.
Vehicle longitudinal acceleration	ABS module	Indicates the current longitudinal acceleration of the vehicle in meters per second squared as measured by the sensors in the RCM and relayed by the ABS module.
Vehicle longitudinal acceleration	RCM	Indicates the current longitudinal acceleration of the vehicle in meters per second squared as measured by the sensors in the RCM.
Vehicle roll rate	ABS module	Indicates the current roll rate of the vehicle in radians per second squared as measured by the sensors in the RCM and relayed by the ABS module.
Vehicle roll rate	RCM	Indicates the current roll rate of the vehicle in radians per second squared as measured by the sensors in the RCM.
Vehicle speed	PCM	Indicates the current vehicle speed in kilometers per hour.
Vehicle yaw stability index	ABS module	Indicates the current stability (oversteer or understeer) of the vehicle.
Vehicle yaw rate	ABS module	Indicates the current yaw rate of the vehicle in radians per second squared as measured by the sensors in the RCM.
Vehicle vertical acceleration	ABS module	Indicates the current vertical acceleration of the vehicle in meters per second squared as measured by the sensors in the RCM and relayed by the ABS module.
Vehicle vertical acceleration	RCM	Indicates the current vertical acceleration of the vehicle in meters per second squared as measured by the sensors in the RCM and relayed by the ABS module.
Vehicle yaw rate	RCM	Indicates the current yaw rate of the vehicle in radians per second squared as measured by the sensors in the RCM.
