systems and fuel pump testing are covered. The history of
emissions control systems, from their inception up to the
present, is included. Control system theory and operating
principles are studied. Service and testing procedures are
demonstrated, and on-car tests are performed on all the
major emissions systems. The latest evaporative leak tester
smoke machines that use nitrogen is used for training.

still briefly covered. Introduction to alternative fuels, electric,
and hybrid vehicles are presented. Highlights of the latest
Pennsylvania Emissions Testing procedures is featured, and
the groundwork of 5-gas diagnostic testing is laid.
AT 206 (3 credits)
Advanced Engine Diagnosis
Covers the use of the Vetronix MTS 5100/5200 Engine
Analyzer, Vacutec Leak Detector, and the Mustang Chassis
Dynomometer. Theory-related instruction is given on 5-gas
analysis and interpreting the results of the analyzer tests with
special emphasis on how they relate to advanced diagnosis
of ignition, carburetion, fuel injection, charging, cranking, and
engine and emission control systems. Demonstrations on
hookup and operation are followed by student practice on
shop vehicles, and when possible, by repair of client vehicles.

Inspector manuals are covered, as per state requirements.
A demonstration of the proper procedure for performing a
safety inspection on a vehicle is given. Students practice on
shop vehicles. Each student is given the opportunity to take
the Pennsylvania Safety Inspection written and performance
tests along with the Enhanced Emissions written test and
computer-based training/tactile test. The Commonwealth,
upon satisfactory completion of these tests, will grant a
license for each.
AT 256 (2 credits)
Heating and Air Conditioning
Covers the theory of refrigeration and the operating principles
of manual and automatic temperature control systems, with
special emphasis on diagnosis, service, and repair. Refrigerant

federal law. The Sun Air-Kare charging station, Everco EREC
Recovery/Recycle station, and the Robinair Enivro Charge
Combination are featured. Demonstrations given on hookup, operation, and servicing, followed by student practice on
shop vehicles, training aids (clutch and seal replacement)
and repair of client vehicles.
AT 261 (3 credits)
Drive Train and Manual Transaxle Service
Basic operating principles of manual transaxles, differentials,
clutches, and universal joints. C-V joints, drive axles,
and drive shafts, along with diagnosis and basic service
techniques. Demonstrations given on differential set-up,
replacing universal and C-V joints, also clutch replacement
and adjustment. Students practice disassembly, precision
measurements, adjustments and assembly techniques on
training aids and work on client vehicles when possible.

Advanced Engine Computer Control Analysis
Sensor-related theory, testing procedures, and waveform
analysis are studied. OBD-II theory and the related testing
procedures are covered. How to use shop manuals to follow
manufacturers' procedures for troubleshooting engine
drivability problems on computer-controlled cars, along
with lab scopes (Fluke 98 Series II), break out boxes, and the
Master Tech 3100 hand-held scanner are used to recover
trouble codes from the computer's memory and reading
sensor stream data. Emphasis is placed on the diagnosis and
the interpretation of the results. Students practice on shop
vehicles and repair client vehicles when possible.
AT 271 (4 credits)
