Service
Location:
Physical Telltale (Position 8 on Cluster)
Color: Amber (Yellow)
Purpose:
This telltale illuminates when the truck
needs to be serviced or permanent
damage could occur.
Stop Powertrain
Location:
Digital Telltale (Position 2 on Cluster)
Color: Red
Purpose:
This telltale illuminates when the truck
needs to be pulled over. Failure to stop
the truck could result injury, death, and
permanent damage to the truck will
occur.
Limited Performance Mode
Location:
Physical Telltale (Position 8 on Cluster)
Color: Amber (Yellow)
Purpose:
This telltale illuminates when the truck
will be severely derated (i.e. below 25%
power output allowed).
Regenerative Braking System
Location:
Physical Telltale (Position 8 on Cluster)
Color: Amber (Yellow)
Purpose:
RBS stands for regenerative braking
system. This telltale illuminates when
the regenerative braking system is
severely derated or not functioning. The
drive will need to rely on the foundation
brakes when the RBS telltale is
illuminated. The RBS telltale can be
illuminated due to normal operating
conditions (e.g. high state of charge) or
due to severe operating conditions (e.g.
extreme temperatures, long downhill
grades, etc.). If neither the Service
Telltale or the Stop Sign Telltale (digital)
are illuminated, the truck can continue
to be driven without risk of damaging
the powertrain.
