FEATURES
PasSmart still operates when there is an active (non-shutdown) system fault. In this situation the
AWL goes from constant illumination to flashing one minute before the VSL ramps down. At
the end of the passing event when PasSmart is deactivated, the AWL will return to constant
illumination if the fault is still active.
If there is an active stop engine fault, the rampdown/shutdown activity overrides PasSmart. The
additional passing speed is not available until the fault is cleared.
For example, if the normal fleet speed limit is 65 MPH, the fleet manager can increase the VSL
an additional 10 MPH for a maximum of 30 minutes per reset interval. An example of these
limits is listed in Table 5-67.

Each time the driver exceeds 65 MPH, the 30 minute clock counts down as long as the speed
remains above 65 MPH. He or she can continue to enter and exit the PasSmart extra speed zone to
pass vehicles until the entire 30 minutes of higher VSL is used up. The driver is warned by the
AWL one minute before the time expires. The vehicle speed is then limited to 65 MPH until the 8
hour period expires and an additional 30 minutes of passing time is available.
5.20.2 INSTALLATION
An OEM supplied Vehicle Speed Sensor or output shaft speed over the SAE J1939 Data Link is
