Comprehensive Engine Diagnostic Information
The training text includes detailed information on the Engine Control Module (ECM),
engine sensors, control circuits, wiring diagrams, connectors and engine harness locations.
It also explains important terminology and abbreviations used throughout the troubleshooting
procedures, making the manual easier to follow during service work.
The diagnostic procedure section provides a structured troubleshooting process, beginning with
confirmation of the user’s complaint and pre-inspection before progressing to DTC diagnosis
and symptom-based fault inspection. The manual also explains the differences between
history faults, intermittent faults and present faults.
Diagnostic Trouble Codes (DTC)
A major part of the manual is dedicated to Diagnostic Trouble Code troubleshooting.
The sample includes DTC information for common rail pressure faults, sensor faults, injector
drive faults, engine position sensor faults, EGR faults, ECM faults, power supply faults and
CAN communication faults.
Examples covered in the manual include P0088, P0089, P0091/P1291, P0107, P0108,
P0112, P0113, P0117, P0118, P0182, P0183, P0192, P0193, P0201-P0206, P0219, P0237,

the supplied sample.
Wiring Diagrams and Electrical Diagnosis
The manual contains information explaining how to read wiring diagrams, including wiring
colors, circuit identification, ECM-related circuits and machine-specific wiring differences.
It also provides information about engine harnesses, connectors and electrical system
diagnosis.
The wiring and circuit information can be particularly useful when troubleshooting electrical
faults involving sensors, actuators, ECM circuits, communication systems and fuel injection
components.
Scan Tool and Diagnostic Equipment
The training text explains the use of diagnostic equipment including Tech2, TIS 2000,
injector checker, flash tool and breaker box. It also discusses scan tool data display
and the differences between Tech2/KW communication and CAN communication.
The manual explains how diagnostic trouble codes can be read through the diagnosis lamp,
machine trouble display monitor and scan tool. It also provides procedures related to
DTC clearing and confirmation after repair.
Fuel Injection and Engine Control System
The manual covers the electronic control fuel injection system, including components such as
the common rail, common rail pressure sensor, suction control valve, pressure control valve,
injectors, crankshaft position sensor, camshaft position sensor, engine coolant temperature
sensor, fuel temperature sensor and other engine-control components.
Symptom-Based Troubleshooting
In addition to DTC diagnosis, the manual contains troubleshooting information for symptoms
such as engine stall, hunting or rough idling, engine output shortage, excessive white
smoke and excessive black smoke. The sample also includes sections concerning noise
and fuel or oil consumption-related symptoms.
Service and Repair Precautions
Important service precautions are also included. These cover electrical circuit testing,
commercial electrical equipment, welding work, electrostatic discharge protection and
high-pressure fuel system components. The manual specifically emphasizes proper handling
of electronic control components and fuel system parts during diagnostic work.
