Display
The OnGuard™ display provides the interface for the driver.
Figure 1.8. Audible and visual warnings, as well as verification of
correct system operation and faults, are communicated to the
driver. The driver is able to monitor the status of lead vehicles that
the OnGuard™ system is tracking. The functions of the OnGuard™
display may be integrated into a vehicle’s instrument panel. If the
vehicle has an integrated display, please refer to your vehicle
owner’s manual for correct operation.

SAE J1939 Network
The SAE J1939 Serial Control and Communications Heavy-Duty
Vehicle Network allows various electronic controllers on the vehicle
to interact efficiently and in coordination with each other. The
interactions between controllers include sharing sensor data,
calculated information, subsystem operating state and
configuration. This communication allows subsystems to influence
each other’s operation.
