The information about the "course" is minimal. I wouldn't be able to tell if this course includes anything on vehicle maintenance without more information.
In most cases, an automotive technology or diesel technology and transportation maintenance courses will include the instruction of maintenance on vehicles, from simple to complex. From oil changes to tire rotations up to engine and transmission overhauls,.
These types of courses would hardly have significant parts on vehicle maintenance if the course is about computer science, engineering, or business.
If a particular course may deal with vehicle maintenance, I would check out for the following:
Check the syllabus of the course; this outlines topics covered.
Consult the instructor who teaches the course; he knows best.
The course description might give you an overview of what the course would be teaching you.
You will know if the course is interesting in terms of vehicle maintenance by reviewing these resources.
