Operation
When the transmission is in manual mode, engine protection
upshifts are disabled. This could result in an undesirable engine
overspeed condition. It is the operator’s responsibility to prevent
mechanical damage to the truck. Under these conditions, use
service brakes and select the appropriate gear, as required, to
keep the engine RPM within operating limits.
Engine Features
The engines are electronically controlled diesel engines. The
engine Engine Control Module (ECM) monitors and controls the
injection process and other engine functions. The ECM also
communicates with the Body Controller (BC) and alerts it to
out-of-range operating conditions. The BC, in turn, generates
engine function indicators and warning indicators. Since many
of the engine performance features are owner selectable and
electronically programmable, some of the operating parameters
will vary from vehicle to vehicle. Some of these standard and
optional monitored engine operating functions and warning
indicators include:
Some Standard Features:
• Engine Warm-Up Control (ECM) – Adjusts injector
operation as required.
• Cold Ambient Protection (CAP) – Aids engine warm up
and maintains engine temperature.
• Cruise Control – Provides vehicle speed control.
