1 CENTRAL MAINE COMMUNITY COLLEGE Auburn, ME Automotive Technology Term: Spring 18 AUT 292 Computerized Chassis Controls Instructor: Carl Hinkley Course Syllabus Course_Description This course will involve a comprehensive study of electronic and computerized brake, traction, suspension, steering, and alignment systems of modern vehicles. A guide to practical experiences in analyzing problems and replacement of faulty sensors and associated components will provide students with theory and procedures necessary to diagnose faults. Course Specifications Credit hours assigned to the course Projected hours for classroom lecture Projected lab, clinical or shop hours Estimated hours required for outside work (reading, research, etc.) Total estimated hours of Student Effort (total of lines 1,2 3) Course_Objectives The purpose of this course is to provide students with an opportunity to: Understand the principles of electronic suspension and steering, theory of repair and component identification Understand the principles of electronic ABS and traction control, theory of repair and component identification Gain experience with smart air bag theory, theory of repair and component identification Perform a body and wheel electronic vibration analysis theory of repair and component identification.
