Integrated Temp-A- Start (Optional; For Future
Support)
Integrated Temp-A-Start ( i TAS) is a fully integrated vehicle management and control
(V-MAC) IV system designed to improve fuel economy by reducing unnecessary
engine idling. When
i TAS is enabled via a dash switch, the system will automatically
start and stop the engine to maintain a minimum engine coolant temperature (ECT),
minimum battery voltage, or a comfortable cab and sleeper interior.
i TAS voltage and
temperature settings are fully programmable through either VCADS software, and via
the Co-Pilot instrument cluster display (if available and enabled).
Note: Safety overrides will prevent the
system from activating if the transmission
is in gear, the hood is up, or the parking
brake is released.

Speed Sensor Tamper Detection
Speed sensor tamper detection is used to monitor and stop unauthorized tampering of
the vehicle speed limiting function in order to gain additional top speed. If tampering
is detected, the vehicle operator will be notified by a diagnostic trouble code (DTC).
Engine power will be limited to a programmed percentage and will continue until the
issue has been corrected.
Note:
Torque limiting will be inhibited
if a driveshaft power takeoff (PTO) is
enabled and active.
