AUT 226

ADVANCED ASM EMISSIONS DIAGNOSTICS

 

 

COURSE CONTENT:

 

AUT 226 is the study of diagnostic and repair strategies for vehicles that fail an Air Check Virginia Inspection/Maintenance test.  The course of study will cover acceleration simulation mode and two-speed idle tests, on-board diagnostic tests, on-road and Diesel OBD tests.  This is not an entry level course!

It is intended for practicing automotive emissions and engine performance repair technicians.  Students are expected to have a working knowledge of basic I/M programs, vehicle electrical/electronic systems, ignition systems, basic exhaust gas analysis, fuel injection systems, basic emission controls and computerized engine controls.

 

OBJECTIVES:

 

Upon successful completion of this course, students should be able to interpret enhanced I/M test results, diagnose causes of test failures, and perform effective repairs to bring failed vehicles into compliance. Successful completion of this course meets the technical competency requirements for the Virginia DEQ Certified Repair Technician license.

GENERAL INFORMATION:

 

A pre-test will be given at the first class session to assess student training needs and to meet opt-out requirements.  Students that do not pass the pre-test will be required to attend a minimum of the first three class sessions.  These students will also be required to achieve a minimum grade of 80% on the course post-test to meet the testing/training requirements for becoming a Certified Repair Technician (CRT) in the Air Check Virginia program.  Student attendance and participation is encouraged, as class discussions and individual input will greatly enhance the learning experience for everyone.

 GRADING:

 

The post-test/final examination will be 100% of each student’s final grade.

 

The grading structure is as follows:

 

A=        91-100%

B=        81-90%

C=        80%

F=        79% or below

 

In the event the student is unable to complete the course requirements and wishes to withdraw from the course, he/she is responsible for completing the required form, NVCC 125-047, before or by the last day to withdraw without grade penalty. This form is available both online and at the Student Services Center.  Failure to do so will result in the student receiving a failing grade for the course.

 

ATTENDANCE POLICY:

 

  • Students that fail to attend the first two class sessions will be automatically withdrawn during the third week of the course.
  • All students who score below 80% on the pre-test are required to attend the next two class meetings.
  • Students that achieve opt-out status must provide the instructor with documentation that they are not receiving financial aid. Students receiving financial aid must attend a minimum of the first three class sessions.  Opt-out students are requested to appear at the final class session to receive their course completion certificate.  You are not required to stay, but please stop in!
  • It is the responsibility of each student to inform the instructor of any problems meeting the preceding attendance requirements. Failure to comply with these requirements will result in being dropped from the course or receiving a failing grade.
  • The instructor and/or the College reserve the right to change the course as deemed appropriate.

 

 

 

RECOMMENDATIONS FOR SUCCESSFUL LEARNING:

 

Proper preparation for each class session will be a key ingredient to your success in this course.  You should plan on a minimum of two hours time each week outside of the classroom to review handouts, work on practice test questions, and complete assigned reading.  If possible, try to invest a small amount of time on the job for practical application of learned concepts.  Also, bring your questions about problem vehicles or your solutions for class discussion!
