Engines that have series turbochargers are equipped
with a low-pressure turbocharger and a high-
pressure turbocharger.
Engine Specifications
The front end of the engine is opposite the flywheel
end of the engine. The left and the right sides of the
engine are determined from the flywheel end. The
number 1 cylinder is the front cylinder.

Electronic Engine Features
The engine operating conditions are monitored. The
Electronic Control Module (ECM) controls the
response of the engine to these conditions and to the
demands of the operator. These conditions and
operator demands determine the precise control of
fuel injection by the ECM. The electronic engine
control system provides the following features:
• Engine monitoring
• Engine speed governing
• Control of the injection pressure
• Cold start strategy
• Automatic air/fuel ratio control
• Torque rise shaping
• Injection timing control
• System diagnostics
• Low temperature regeneration
For more information on electronic engine features,
refer to the Operation and Maintenance Manual,
"Features and Controls" topic (Operation Section).
Engine Diagnostics
The engine has built-in diagnostics in order to ensure
that the engine systems are functioning correctly. The
operator will be alerted to the condition by a "Stop or
Warning" lamp. Under certain conditions, the engine
horsepower and the vehicle speed may be limited.
The electronic service tool may be used to display
the diagnostic codes.
There are three types of diagnostic codes: active,
logged and event.
Most of the diagnostic codes are logged and stored in
the ECM. For additional information, refer to the
Operation and Maintenance Manual, "Engine
Diagnostics" topic (Operation Section).
