New Model Updates
Boxer Engine: This Technicians Reference Booklet
introduces the Subaru 2.2 liter (SOHC) naturally aspirated (N/A), (Phase
1) and (Phase 2) engines, the 2.5 liter (DOHC) (Phase 1) and (SOHC) (Phase
2) engines, the 2.0 liter Turbo engine and the 3.0 and 3.3 liter six cylinder
engines.
Basic Electrical Theory and Diagnosis: This Technicians
Reference Booklet contains information pertaining to basic automotive
electricity, and the Subaru electrical system. It reviews electron theory,
current flow, circuitry, and the types and causes of electrical shorts.
Electrical terms are defined, Ohm's Law is explained, and the following
major components of Subaru electrical systems are discussed: the battery,
circuit protectors, switches, relays, and motors. Finally, the six-step
method of troubleshooting is introduced. This method presents a logical
step by step process of identifying and correcting typical electrical
system problems.
Advanced Electrical Theory and Diagnosis: This
Technicians Reference Booklet contains information pertaining to advanced
automotive electrical technology, and the Subaru electrical system. It
reviews solid state devices, operation and diagnosis of Subaru starting
and charging systems, operation and diagnosis, computer terminology and
operation, and the troubleshooting and diagnosis of intermittent faults.
In addition, the use of the Select Monitor is also explained during the
presentation of the module and will be demonstrated during the lab exercises.
4EAT (Auto Transmission): This Technicians Reference
Booklet introduces the first generation of Subaru Four Speed Electronic
Automatic Transmissions. It covers the components and their operation,
its self-diagnostic system, troubleshooting, transmission removal, inspection,
reassembly, and reinstallation procedures. The differences between the
front-wheel-drive (FWD) and the four-wheel-drive (4WD) transmissions are
also illustrated.
4EAT (Auto Transmission) Phase II: The 4EAT Phase
2 (introduced on 1999 Model Year vehicles) provides the same type of electronic
control used by prior model year vehicles and shares many of the same
diagnostic procedures, however there have been internal and external changes
that require this 4EAT to be viewed as an entirely new automatic transmission.
Additionally, beginning with the 2001 model year, an enhancement to the
all wheel drive transfer section was introduced. This enhancement, Variable
Torque Distribution (VTD), is covered in this reference booklet starting
on page 9.
Basic Emission and Fuel Systems: Today's automobile
is the refinement of research, which through the years has led to a computer
controlled machine sensitive to both internal and external influences.
It is able to provide optimum performance throughout a broad range of
atmospheric conditions, fuel quality, engine condition and driver demand.
The information covered in this course will get you started with the knowledge
base you must have to effectively analyze conditions, situations and problems
associated with vehicle emissions.
Fuel Injection and Engine Management: This Technicians
Reference Booklet contains information about Subaru Fuel Injection and
Engine Management systems. The objective of this class is to provide training
that will assist you with properly diagnosing and repairing the Subaru
vehicle in a timely manner the first time.
On Board Diagnostics-II: This system combines engine
and automatic transmission "Diagnostic Trouble Codes " or DTCs that have
an affect on vehicle emissions. The number of codes and the diagnostics
for codes is always changing due to the introduction of new components
and newer operating logic for them. But the key to diagnosing OBDII remains
the same. That is firstly understanding the systems that are being checked.
Then apply that understanding to the logic provided to the OBDII system.
Break Systems: This Technicians Reference Booklet
introduces the brake systems used on Subaru vehicles. It covers the component
operation, trouble-shooting, diagnosis and service precautions and procedures.
This information is presented with special emphasis on procedures, tools
and materials unique to the Legacy, Forester and Impreza vehicles.
Supplemental Restraint System (SRS): The SRS System
features built-in Self Diagnostics and a redundant Safety Design with
back-ups built into all of the circuits. The system safeguards include
double locking connectors with diagnostic sensors, a selfshorting inflator
SRS air bag module connector to prevent accidental deployment during servicing,
and a steering roll connector. A capacitor supplies back-up power. Finally,
for redundancy, there are two front inertia sensors and two safeing sensor
circuits.
