General Information
Some New Cascadia trucks equipped with Detroit Diesel New Final Drive (NFD) axles have a high temperature warning
parameter. The warning is set too low for some applications, and under certain conditions that are not harmful to the axle, the high
temperature warning will appear on the dash and indicate an error requiring service. If a truck comes in with a complaint of a high
temperature warning that displays when the axle is not above the maximum temperature cited in the Driver’s Manual, the
temperature parameters can be changed using DiagnosticLink®.
